Vag Commander with VCDS cable

[caldy315]

Awhile back I was trying to make a couple of new keys for my car. Researching and asking a couple of questions, I learned the process. That said, no one said for sure if they could confirm if a genuine vag com cable would work with Vag commander to retrieve the SKC.

Has anyone successfully done this? I recently just go the cable (came today) and want to get a few extra keys made, but was unsure if this cable would work and don't want to brick anything. I don't have a blue ebay vag com cable and if I can do it with my Hex-CAN then it's one less thing I need to purchase.

Thanks

Put VCDS to boot in "dumb" mode and Vag commander should run through a Hex Can, but by most accounts it won't run through a KII-Usb cable, wont run through mine anyway.
So- you should be good to go.

I can't speak for the genuine cables, but I know the cheap ebay ones work.

As "rollerton" mentioned, you need to set VCDS to use "dumb" mode on the cable. Do this by Un-checking the "Boot in intelligent mode" box in VCDS Options Settings tab, then close and restart VCDS, then close VCDS again. Next, open the other application and see if it connects.

Alright, I posted this thinking I had everything ready. Realized I never downloaded the Vag K-Can Commander software from a PM from a member. Now that link doesn't work. The link in my bookmarks is bad too. Can anyone shoot me a link to a download?

[caldy315]

Alright this appears that it's not going to work in my favor. I downloaded Commander 2.5 and installed it. When I open it, it asks for a COM Port number 3-6. Not knowing much about computers, I know that my Hex-CAN is a USB device and if I understand right, doesn't use COM ports. I pick an arbitrary port, and keep on. I select K line, go to ECU and click the second option just as Imnuts steps are in his tutorial. On the bottom it says can't connect, trying 3 times or something to that effect. Can anyone explain what I'm doing wrong? Can't seem to get my head around what port I'm in, and what needs to be selected in Commander. This is the tutorial I'm following

https://sites.google.com/site/imnuts/


EDIT: I see that you have to have the cord emulate a COM Port with virtual com port. I installed the drivers and now it looks like it's working as a COM port. In the morning I'll check to see if everything worked as I want it to.

[caldy315]

To close the loop, it was something with my computer or the version of vag commander I installed. Worked on another computer. So you can use at least a HEX-USB+CAN VCDS cable in dumb mode with Vag Commander. Make sure to download the VCP (virtual COM port) drivers from Ross Tech and install/update drivers.

Hi all
I only joined Audizine recently but I really need some pointers. PLease! I've an 03 A4 (B6) 1.9 tdi.

In a nutshell. My instrument cluster somehow suffered electrical damage. Earlier this year I sent it to 2 of the 'best' cluster repair centres in the UK without any luck. I wasn't given much to go on except told it was beyond repair, and that they couldn't pull info off the processor or something to that effect. all along I've wanted to change my cluster for a matching cluster. Garages won't touch the job, in fact all but 1 VW/Audi garage, and he only said he'd fit Brand new. If he or the nearest Audi dealerships do it, it's too much ££ for me. I've got a matching donor cluster on the way via ebay, as I type, and the seller has given me the SKC code for this which will save me some hassle.

I bought a USB OBDII 409.1 Cable VAG-COM 409 cable from ebay. Works with the VCDS Vag com 409 it came with on a CD. I've also downloaded Vag K commander, vag tacho. I've only partially had some connection with Vag Commander 1.4. and no luck with vag tacho. Vag commander goes as far as allows me to select the cluster tab, but It doesn't retrieve any data, for any module in fact.

I'm assuming my cable may be set up slightly wrong? but I don't even know if it is hex can compatible or whatever?

Any ideas? Any pointers? Should Vag commander be able to get the SKC off the ECU do you think?
this is the cable I bought. http://www.ebay.co.uk/itm/350982332148?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

I've got the SKC from the guy sending me th donor cluster. All I need Vag Commander to do is get the SKC for my cluster OR failing that hopefully get it off my ECU (if my cluster's memory, or chip is too damaged). Then swap clusters by Adaptation.

[mats17]

With Vag Commander, newer versions than V1.4 are available, I believe I tried V4.5 but got "target unit not responding". V1.4 at least seems to connect! It gets a little bit confusing with..is my B6 A4 'K-line' or CAN, etc. But basically, I seem to have some connection with Commander 1.4 although it hasn't produced the goods yet. There may be a slight difference in my cable and a Vag commander cable? (even as cheap ebay versions go that is) ?

I'll need to:
1) get my SKC from either the cluster(if poss) or from my ECU. I've been given the SKC code for the cluster I'm buying;
2) Swap clusters over / Key adaptation;
3) set mileage correct on the donor cluster. My mileage is more than double that of the donor!

[caldy315]

Just a few pointers although I'm relatively new to this too. Someone correct me if I'm wrong. Vag commander is a program you downloaded. You can use your eBay cable or use a genuine Vcds vag com cable in dumb mode.

Hex can is the type of vcds cable I happen to own. This covers up to current Audis. You can get a older version that does up to the B6 but doesn't communicate over CAN bus like the new cars do.

From what I have read and been told, DO NOT TRY to read the cluster from vag commander. Apparently you can brick it from what I'm told. Do yourself a favor and try and find vag commander v2.5. It's a newer but not the newest version. Then search a member names "imnuts" on this forum. On the bottom in his signature he has a link that will walk you through getting the skc with vag commander FROM YOUR ECU.

I don't know if the two match as I only have my ecu skc. As well as I don't know how to do anything cluster wise, I'm just trying to make an additional key

Like Caldy mentioned, with an ebay cable you need Vag commander 2.5. Then follow imnuts directions here (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CCsQFjAA&url=https%3A%2F%2Fsites.google.com%2Fsite%2Fimnuts %2F&ei=saZfU6uDAemwsASK7IHADw&usg=AFQjCNHjsGZGni_FB7529Mr__JWptQXRrQ&sig2=HpSMUledGMjxLaZEbG_g3w&bvm=bv.65397613,d.cWc). Then follow Ross-Tech's directions on swapping clusters (http://wiki.ross-tech.com/wiki/index.php/Immobilizer_III_Immobilizer_Swapping_(Instrument_C luster)).

I myself am trying to figure out how I can get the SKC code from a donor cluster. I picked up a cheap Vag-Tacho cable, but it doesn't appear to work.

[mats17]

Thanks guys. Have been busy! Going to posting on this one as it could be of use to someone. Even if I don't post for a week or so at a time. I'm expecting the donor cluster hopefully over the next 3 days - then it's bank holiday here, so if it doesn't arrive I may not get it until midweek 7th May. I need to decide on, and order another cable I think, something that will utilise Vag Commander 2.5.

I clean remove the cable's driver files that it came with for VCDS KKL409. I then plug cable in, so XP can find the approriate drivers for USB serial 2.0, tell XP to include the Vag Commander drivers folder...but that doesn't work for some reason. So with my cable, so far, I have had limited connectivity with Commander when it was using the cable setup with the VCDS CD drivers that the cable came with.

I hope to clean get in via cable, retrieve my own SKC code, then swap over using VCDS.

Here's a video from Ross Tech - if you haven't seen it yet, well it may be of use, on Immobiliser 3 ECU and Cluster swapping -
http://www.youtube.com/watch?v=J5_51qeEyec

http://www.youtube.com/user/RossTechVCDS/videos

The guy who's sold me the cluster has tried to be helpful, but his approach is to swap the chips over on the clusters - the downside to this is 1) I'm too sh*t scared to try this, and 2) I need to have my mileage corrected to match my own, faulty cluster. And I haven't even found anyone who can swap clusters with software here in the UK (unless it's brand new through AUDI dealer!) so the chances of anyone being able to swap the chips....No, I don't think that will happen.

Regards
Mathew

[mats17]

And yes Caldy, Vag Commander you can download. e.g...http://www.resettools.com/vag_k_can_commander_2.5_2.0

I did leave it try read the SKC on the Cluster with V1.4. My cluster is knackered anyway, but I certainly didn't intend to make it worse.

[mats17]

Update - Cluster arrived from East Europe (thanks Ebay!) The seller has been helpful, but say's to go down the route of swapping the EEPROM chips over from cluster to cluster. Should that work, then I'd 'guesstimate' that I'll need to still adjust the mileage using a tool such as Vag Commander.
So now I have 3 or 4 options, whereas a month or so ago I thought I was screwed!
I haven't yet found a suitable cable for Vag Commander, and my Vag Com cable (Ebay vag com) will not talk to the car / K-line / Can Bus / whatever with Commander. Just won't do it!
Options are now:
1) swap EEPROM chips of the clusters (has potential but scares the hell out of me!)
2) Use a local VW/Audi tuning shop that I found a few days ago (they say it isn't a problem)
3) Choose and order a Vag Commander cable (and cross fingers that works!)
4) Go to Audi and be penniless the rest of the year!

Will update soon!

[walky_talky20]

I've had good luck with VAG-Tacho for reading the clusters in MK4's and B5.5's with immobilizers. I can't say that I've done a B6, but it should be pretty much the same thing. I think I tried Vag Commander and couldn't get it to work for me.

[Toronto5.5]

I've used Vag Tacho to read mileage on a V6, never tried writing to it though, too scurred.

[mats17]

Update:

Opened the Cluster on tuesday, to find this EEPROM chip. In order to get at both sides of the circuit board, it is necessary to disconnect 5 data cable connections. Since doing this most of the pixels showing the total mileage of my own cluster (knackered cluster that I will be replacing) have gone corrupted. The mileage cannot be read by eye.

SO I would advise DO NOT DISMANTLE THE CLUSTER BOARD, the way I have.
I'm still looking for a Vag Commander cable!
Mat

[mats17]

May 25th... Got a cable for Commander, configured it. Connected it up.
I had the guide from Imnuts to refer to, but my aim was just to find the SKC of my instrument cluster via the ECU or Cluster.

I couldn't connect to the ECU. I don't know why.
I only tried using the settings in Imnuts guide however. If anyone has any ideas?

For some reason I tried the cluster. I connected via Audi Bosch setting, and also Audi Bosch Crypto, with the same results each time.
I had some strange readings... Odometer read 322640 (when my actual mileage is approx 149,000 miles). I was also shown a 5 digit Login???

Can anyone shed any light on whether I've had a garbage result from the cluster? I've saved the .bin files each time.
Mat.

[caldy315]

I only tried to connect to the ecu to pull my SKC. I had a few troubles but got it eventually. I used a genuine Ross tech hex can cable. Had to download a few drivers but it worked after that.

I'm not sure how to pull info off the cluster. Maybe check out nefmoto.com. I think that's the forum that deals with this cluster/ecu stuff exclusively

[k0mpresd]

i would only use a genuine trusted cable on the rb(x) clusters.

[csosnowski]

Commander wont read the pin from a bosch rb(x) encrypted cluster.

You have to log into the ecu with commander and get it that way.

If reading address 01 gives you garbage and a 5-digit login, try reading from address 11. I had this problem with a 2005 C5 Allroad.

As k0mpressed said, the bosch rb(x) clusters are picky. Almost as picky as the marelli clusters in beetles. Be careful.

What do you mean you "had a few troubles"? You have managed to get your SKC Caldy?
Did it just take you many attempts to connect? or do you mean that after getting driver files and the basic settings and configurations of the software and cable..that you were then ok?


With mine, everything seems to work fine. I have an Ftd chip based cable, several commanders to use, but 2.5 I have been trying. I try with the key out, with the key in, with the key in and ignition on position 1, then tried with key in and ignition position 2. Basically I've tried connecting to the ECU, as per the Imnuts method...but he doesn't state to do it with engine running or what?

I couldn't connect to the ECU.. Do you mean try using wakeup pattern 11 instead of wakeup pattern 01??

Commander did read 'something' from the Cluster.. Am I just to assume that it's garbage? Or with the PIN, is it worth me trying to log in with VCDS? I could disregard the 1st digit, leaving me with a 4 digit number?

[mats17]

One last question.. If I'm going to be unable to even Read from my cluster...How will I be able to adjust the mileage?

I've gotten my SKC off my ecu to program my keys. With my personal computer it didn't want to recognize the hex can cable as a com port even with the drivers from Ross techs site.

I did everything over again because a guy from nefmoto was helping me and said it should've worked. I downloaded everything again on my work comp and it worked first try. Everything on mine looked legit and matched up

cheapest thing off hand is probably a genuine vagtacho. not the china clone crap. i have used mine on rb(x) clusters without any issues.

[Myst420]

Very true...but with the tools the OP has, it would have to be virginized first. I've heard good things about VagDashCom from eBay, but never tried it myself.

Also " DejaVu (http://www.dialab.ee/dejavu/Support/)" if you can find somewhere to buy it. Don't fiddle with the Rbx cluster with cheap tools.
Just don't, you'll regret it.

[mats17]

I looked into buying Vag Tacho -cable, And it seems it isn't for sale any longer! (V.5 or older).

Think I'll be happy just to find out my SKC codes for now, and get someone to change the cluster and set the mileage straight.
Although, if I know the SKC codes, It doesn't look that difficult to perform the adaptation and cluster swap.

A cluster can be virginized then, as opposed to being a 'virgin' or new cluster.
This, I admit, I don't understand, but I'm guessing it would involve erasing or clearing the chips' memory?

[Myst420]

Yes, with the right software, a cluster can be reset so that it's like a new one. I tried with an s4 cluster a little, but never had any luck. I ended up contacting mpower on here and Tom was able to do it for me.

I would love to just swap the chips over from cluster to cluster. But I literally don't have a clue.
At least I'm quite versatile with software. Proper hardware..is the issue it seems going by the advice/comments here.

[mats17]

Thanks guys for the VAGDash suggestion.

Vagdash sounds like the way to go. But is it 'Vag Dash Com' or 'Vag Dash Can'?

I've just managed to get a 3 digit login number from the ECU- but via the VAG-EDC15x connection from the drop down menu of VagCommander 2.5. I couldn't get anywhere via either of the 2 VAG-ME wake-up patterns (01 or 11).
Looking at my original VCDS scan result, and one I made this eve, I knew I could connect to the ECU, but it seems that there is some possible blocking/interference by the Cluster.
From using the VAG-EDC15x Connection to the ECU, I managed to get credible data, including a 3 digit Login number ending with '6', which if my memory serves me correctly, may indicate previous tampering or alteration?
Anyway, I may have managed to obtain my PIN via the ECU, I will research this soon. But I will still be in the same boat, and I still need to swap the clusters over and correct the mileage (increase the mileage of the donor cluster)

[xhackerekx]

with Vag Dash Can u can obtain u pin change millage whatever cluster is virgin or not .

[mats17]

Thanks. I'm looking into getting VagDashCan.

Also ,it seems from reading, that most most petrol vehicles will have the engine management system (EMS) ECM type "ME7.x" and with most software that that would be the selection.
Diesel systems: being ECM type EDC15x fitted (where x is the EMS system variation).

Which..if anyone follows the SKC pull guide/s, may explain something of help in choosing your selection of connection.

So..
I found some 'normal' looking data off my ECU, with VagCommander, for my TDi using the VAG-EDC15x selection. I obtained a 3 digit LOGIN.

Likewise with my cluster using either the "Instrument Cluster Audi A4 Bosch RBx" selection or the "Instrument Cluster Audi A4 Bosch RBx CRYPTO 2001+" selection (same, repeatable results with each) but this time with a 5 Digit LOGIN???

The ECU scan yielded no Odometer reading- while the Cluster gave me a mad one! And Neither ECU or CLuster logins match - but according to Nefmoto forum, they won't necessarily match. Left me confused as to what to do with a 5 digit login or a 3 digit one now!! Which to use where, when and how??

If you try read the saved bin file using VagCommander, to read it 'offline' (while unconnected to your car OBD port) you get blank fields in the Login and odometer boxes (which is where knowledge of the code comes in i spose!)

Don't know if this'll help anyone in future.

Every PIN/ SKC I know of for VW / Audi Immo through generation 3 or 4 is a FOUR-DIGIT key. When you read the login with various programs you should get anywhere from 1 to 4 digits. Say it returns a PIN of " 41 " . The PIN is actually 5 digits with the first always being zero- so the actual SKC/PIN is 00041. Likewise if it gives you 3236 or "7" the SKC will be " 03236" or "00007" .
I've never known an SKC to start with a non-zero and be valid. I hope you find a program / dongle combination that does indeed work, that would be great. I'll tell you I spent hundreds of dollars on chinese copies when I first got my B6 and NONE of them got through the clusters encryption- that was a few years ago, so there's hopefully a few more options by now.
FWIW pulling the SKC from the ECU really should work with B6's though late 04' if it's done right.

[mats17]

So, I've read up on Vag Dash Can. No real horror stories found, such as people using it and things gone Tits up. But..likewise, as Rollerton you try explain, it can be hit and miss with success.
Looking at getting Vag dash K+Can - again it opens up the mysterious world of what cable, or cable+software passes as 'legit' or 'proper'? What would be considered cheap chinese crap.? What isn't chinese crap (as most cables,etc are made there thesdays I'd assume!)
So what to look out for?
Also another issue for me, I have Vag Commander K+Can which installed cleanly, and does connect up fine. And other forum members have had success with that - many first time successes, straight into the ECU even the cluster? if I'm not wrong.. So a)I don't know if I will be wasting my time with ANY software+cable combo, as my problems could be just severe enough that using a communications link would be futile? I may need a pro to hook up on a bench or whatever? Meaning that however good my VagCommander is...It may never solve this problem.

b)How authentic has my Vag Commander Cable functioned? I don't know enough about it I can honestly say! I managed to save bin files from the ECU-EDC15x , and the Cluster(likely to be garbage?). The Login given from the ECU matched that given when I used a code calculator. BUT I couldn't get anywhere with VCDS-Login(possibly for similar cheap chinese issues?), after entering the 5 digits I could wait all day and it gets nowhere. And with my cluster, some others on forums have managed to supposedly got somewhere with Vag Commander to work even with IMMOBILISER 3 stage clusters.

Edit: just read that vag dash com 1.65+VAG dash can 5.17 doesn't support Audi A4, only up to year 2000.

[caldy315]

Mats I forget what exactly you're trying to extract, but if it's the skc you should be easy only able to do it with vag commander. See if someone around you has a legitimate cable and borrow it for a day. Put it in dumb mode, download the drivers off Ross techs site and give it a whirl. It worked for me. But I'm not trying to write mileage to a non virginized cluster either.

Hi Caldy, yeah the SKC or Pin code that would allow me to swap my damaged cluster with a working cluster. And unless I could swap the chips over (retaining the mileage, etc,) I will need to correct the mileage in the donor. I failed to do so with Commander and VCDS. I retrieved a 3 digit code and a 5 digit code when I tried reading the cluster. It was worth a try.
I am possibly going to try vag dash, maybe v4.2?

To get your current skc, you need to read the ecu with commander, not the cluster.

I read on nefmoto forum that the PIN codes of the ECU and the Cluster won't necessarily be the same. If the cluster came out of the same car it will have the same SKC as the ECU; and i can't be 100% sure that either have been replaced or not during the cars' lifetime!

While trying to get the ECU EDC15 eeprom data and ultimately the SKC, I managed to find a codechecker which checked the saved .bin file, and returned the same 3 digit Login number that commander did. During this process I looked far and wide for an answer, and even sent my .bin file to EcuCalc (their website popped up somewhere). I checked my email this morning and I'd had a reply from them stating that the .bin file I'd sent couldn't be an EDC15 Eeprom file! The size of file should be at least 32 KB. My file was only 512 bytes.
So, I'm just assuming, that if that is correct, my VagCommander has been useless.
I tried logging in with VCDS using 1)the 3 digit Login retrieved by Commander - , and 2)using the 5 digit login from the cluster (I'd soon assumed that this would be 'nonsense' data as the cluster is encrypted).
In each case VCDS just hung and hung, all the time saying 'connecting' or something like that.

[diagnosticator]

For ME 7.5.n ECUs, the SKC is in the ECU hex .bin at locations 32 and 33, the values are converted to decimal and transposed.(xxyy > yyxx) Then a leading 0 is added to the four decimal digits comprising the SKC. (= 0yyxx)

I don't know if the EDC15 is the same or not. There are no TDI B6 A4s here in NA.

I don't know either!!

I haven't found anything on the EDC15 ecu's yet. The nefmoto tools/software that they use for reading the eeprom chips...work on the ME7 and so on,petrol engine ecu's.
Nothing yet have I found to refer to. So I'm hoping that the next bit of kit I've ordered...a)actually arrives, and b)that it does all I need to do now. I'm getting Vagdash k+can.4.2
x'ing my fingers this gets somewhere.

May 25th... Got a cable for Commander, configured it. Connected it up.
I had the guide from Imnuts to refer to, but my aim was just to find the SKC of my instrument cluster via the ECU or Cluster.

I couldn't connect to the ECU. I don't know why.
I only tried using the settings in Imnuts guide however. If anyone has any ideas?

For some reason I tried the cluster. I connected via Audi Bosch setting, and also Audi Bosch Crypto, with the same results each time.
I had some strange readings... Odometer read 322640 (when my actual mileage is approx 149,000 miles). I was also shown a 5 digit Login???

Can anyone shed any light on whether I've had a garbage result from the cluster? I've saved the .bin files each time.
Mat.


AFAIK, all SKCs are either 5 or 7 digits. When the .bin is less, either 1 or 3 leading zeros are added to the digits to complete the 5 or 7 digits. 5 digit SKCs will always work, are derived from the .bin, whereas the 7 digit SKCs where determined by the dealer with an online connection to the factory and unique on the day generated. On A4s with the original cluster and ECU the SKC stored in each .bin is the same. Clusters and ECU replaced by the dealer will be the same and the same as the original SKC.

I had my local locksmith run his SKC tool on my 05. Looks like his tool is a cheapo. He told me to omit the first number and put a zero.

I have not confirmed this has worked as I am waiting for new glass immobilizer chips to arrive.

You say a 'cheapo' looking device. But it could be pretty good. There's so many devices out there to be bought. Some of them must do something other than collect dust!

The chips you're waiting for..Are they ID48 chips?

[mats17]

I went ahead and put two zeros at the beginning of the 3 digit Login that I have, and it may be due to the 'cheapo' blue vcds cable I have using CH340 chipset, but it seemed that trying to log into the cluster, The yellow key symbol for the immobiliser, lights up permanently (for the duration of the vcds exercise that is) which could mean I've got it right?
However, the program just hangs and hangs, and I must admit I gave up after a few minutes.
In the top left is a rotating cross symbol. which shows it is thinking, processing.
But I could be almost there with it.

Trying to login to the ecu has the same result, the program just hangs. But at least with the cluster, there was something showing up, even if it just the key symbol.

I also have the HexCan cable using FTDI chipset, but this gets nowhere - well not as far as the blue cable!

[mauromj]

More than likely a dumb question, but its something im not sure on. I am trying to retrieve my SKC via vag commander 1.4 and my blue ebay "VCDS" cable. Will this cable work, or do I need a HEX CAN cable?

Yes I am waiting for ID48 chips since I cracked my original ones. Once they come in, I will try to program them myself using VCDS but I have a buddy working as a Audi Tech who can do it for me.

Here is the pic of what I was talking about....

Wow! So you aim to put a zero in front of the last 4 digits? Go for it. Just try it anyway, you could log in, and then then log back out.

I honestly cannot answer that myself!
Maybe someone else can shed light, or look at some other forums? I myself am reading over it all again, going through other forums to make some sense as I don't seem to have full usage of my cables. My VagCommander cable was bought to use with VagCommander 1.4 and is Hex K+Can and has FTDI chip. It does work. The blue 'VCDS' cable is CH340 chipped and I didn't manage to get that to work at all with VagCommander.
But at least you can try! I think I've read somewhere that it can be done. But it depends mainly on cables and chips, and possibly a bad copy of the software I've read.
I've only personally had any luck with VagCommander 1.4 and 2.5. Nothing later than those.

As long as you set the usb port as port 1 or 2 or 3 or 4 AND refer to this in the Tester.cfg file then you should know as you try the program with connection error messages at the top of the screen.

[mats17]

I cannot start a new Thread, but I want to ask Does Anyone have any guide or instructions (with pictures ideally) on how and what to remove and solder in the RB4 Clusters? I've searched and searched for this. The 24C08 chip would only be part of the job, if I understand this correctly?

There was a little something on the archived Audiworld forum..but it was a small amount of info, and any images have long gone.

EDC15 skc can be found at end of address 0000130, and beginning of 0000160. found and calculated in a similar way to that that applies to the ME.7 (petrol ecu).
Mat

[rollerton]

It's not that complicated; you're dancing around a whole bunch of questions that have been answered. The "SKC" for your cluster and ECU are the same. That is to say the SKC is actually the login code for the IMMO system of the car, it is not specific to any component. When the component (ecu or cluster) is removed it retains THAT SKC until it is matched to a different one, on which case it takes on the new systems' SKC.

The SKC for the B6 (Immo3 in all VAG cars) will be 5 digits. The first digit is ALWAYS ZERO.

If you're returned a two-dgit SKC by some reader, then use ZERO for in front of the SKC you've got to make 5 digits total.

If you have a cheap (copy) VCDS interface it will very likely NOT do the IMMO adaptation, but if you've acheived the "solid" IMMO icon in the dash then you've probably got the right SKC, that usually means the module has accepted the login. But Ross-Tech has tried to ptotect their product and have made it very very difficult for pirate hardware to run their software with all options.
Get a proper Ross Tech cable, seriously.

As for the soldering? If you're stumped at this point...do yourself a favor and don't bother with the soldering. Not saying you can't get it done, but you're about to end up with two broken clusters. At that point the dealer owns you.

[mats17]

Uhhh nope! no on has answered rollertron. SKC isn't a problem. I'll sort that if I haven't already.

I have NO CHOICE BUT get it done. I find it hard to believe that the chip procedure and locations are secret knowledge, and for example how have you learned all you've learned? Sure I bet you've dabbled a lot, made mistakes, made calculations..whatever. BUT I BET that you've had advice and knowledge from others.
That's all I've asked. You may be right. But I have no choice, and especially as the mileage is an issue.
I ordered VagDash and that was wrong because of it's origin. Can't get the original. Can't win.

Mat

edit:if I can't solder, I'll find an electrical wizz who has an interest in this (I think I know of someone, an old mate, highly skilled who can.

[Myst420]

Mat,

rollerton is one of the few people on here with a decent amount of knowledge about our clusters. Why don't you try and email Tom @ SpeedoSolutions.com (https://speedosolutions.3dcartstores.com/crm.asp?action=contactus) and see if he can help. He's always been more than willing to help me when I needed it.

I'm still confused as to why you're wanting to solder the chips. If you already have the skc from the new cluster, and you can get the skc from your ecu, you shouldn't need to solder anything to adapt the new cluster.

[mats17]

Sorry Rollerton, I wasn't having a go. Just frustrating not being able to sort this out.

If/when the exchange is done, the mileage will be almost a third of what it should be. My intention isn't to have that, I must have the correct mileage.That would be enough a reason to change the chips over. Saying that, both techniques scare the hell out of me.

[rollerton]

Hey, no offense taken, it's just that there's typically a thread or three a month that cover this pretty thoroughly.
So...what's still the trouble? Having problems getting the SKC?
#1. You can run Vag K+ Can through a a hex can Ross Tech cable in dumb mode, read SKC from ECU ( https://sites.google.com/site/imnuts/ )
#2. Adjusting mileage?
The cluster MUST be in virgin (mode 4) mode. You'll need to spend a chunk of money to get a tool to do this, it'll be many hundreds of dollars at least. The one I know about is called Deja Vu. There are way more people in the UK familiar with it than here.
OR!
You can try and read the dump (eeprom) from your old cluster and write it to the other one. I've done that a hundred times on Immo II / III vw's. Not on a Bosch Rbxx cluster.. it's quite a bit different. Problem with that is you try it and if it doesn't work the cluster is destroyed. Seriously- no warning and you wan't know until you try. There are a few people who can usually rescue it, but just send it to them to start and save the trouble.
Swapping chips? Go for it..again, maybe it'll work, or maybe you touch the wrong micro-resistor and the cluster is bricked. Don't know until you try.

I messed with clusters for years when I had VW's, easy. But when I got my B6 I gave up and paid the smart people when I wanted to swap in a color cluster (after spending hundreds on tools that didn't work). There's no easy "rescue" with these clusters if you screw up.

[mats17]

Hi all I have a question, something I'm trying to suss out.

Does anyone know if I'll need a new key/s(fob & chip) when I've swapped my clusters over?
The RFID chips can't be reprogrammed with immo3. So the keys I have which work with my current corrupted cluster will they be unusable after the changeover? I know about the adaptation process, but I didn't get a key with the donor cluster that I bought! Bit confusing!

Mat

[diagnosticator]

If the new cluster immo is cloned from the old cluster, the key adaptation does not need to be done. IF the new cluster immo is different, the keys need to be adapted to the new immo Id. The RFID chips don't change their programing, the cluster immo adapts to the RFID chips. See Ross-Tech for swapping clusters.

[mats17]

Thanks diagnosticator. Yeah I keep reading over and over the same stuff. I have looked at the RossTech stuff, walkthroughs, wiki's, the main website...guess I'm easily confused.
I was aware that the RFID chips don't change, just got confused on which way around it affects everything.

[mats17]

I'm going to have to abandon the Project I think.
Thanks to those who've Actually helped and not just bragged(you know who you are!)

I'm uncertain of the swap process - and also uncertain of my cable (I don't want this to go badly).
I'm giving up trying to translate from German. The only info I seem to have found on VAGdash...is in German - that being people's experiences and views on it, the pro's and con's. But this is minimal help. The overall verdict seems to be don't touch RB4 or Magnetti M clusters.
The manual for it is in German, and I've translated parts which are not much help in the overall swapover process.

Don't know what I'll do as the variable cost estimate the local tuning shop have given, is getting up with main stealer cost.
I don't trust the software cable options I have combined with my knowledge to even just turn the Immo off to fit my replacement cluster.
I'm thinking just scrap car, as I can't find someone in UK to even post both clusters to to sort.

Can you borrow a car for a couple weeks or do you have a spare? Send the clusters to someone in the US that can do that for you and then you don't have to scrap the car. It would be quite the waste to scrap a car that works except mileage on the cluster unless there is something beyond that

It's a good idea, thanks [:)] I can't loan a car unfortunately, and Ive got to do something soon, as I won't get lifts to work. I keep looking for a cheap motor. Maybe if I can afford one in the mean time, and somehow get this fixed?
I've got the vagdashK+can, VCDS, the correct PIN's, but it's hell of a risk, I'm not totally sure of that bit, keeping above a minimum power supply down the K'line, etc, and if it doesn't work...I can't see me getting another cluster with my model number! I was lucky to obtain the one I have. If there were quite a few to choose from ebay, salvage yards, etc. Then I would definitely give something a try.

[Myst420]

The model # of the cluster doesn't have to be exact. As long as its a RB4 cluster from a B6, it will work in your car. I'd hate to see you get rid of a car just because of the cluster. Is the Vagdashk++can cable one like this (http://www.ebay.com/itm/2014-VAG-DASH-CAN-V5-29-NEWEST-High-Performance-/140992601342?hash=item20d3d05cfe&item=140992601342&pt=Motors_Automotive_Tools&vxp=mtr). If so, you should be able to simply clone your existing info onto the new one.

I have several extra clusters collected over the years. Maybe you can buy one from me and send it to be virginized on it's way to you in the UK. Then you don't have to mess around with the Chinese tools.

[rollerton]

I don't know how it's so confusing.
1. Blue "ebay" vag com KKL cable : clicky click blue cable (http://www.ebay.com/itm/KKL-VAG-COM-409-1-OBD-2-II-USB-Diagnostic-Cable-Auto-Scan-Scanner-Tool-Interface-/310651623301?hash=item4854479785&item=310651623301&pt=Motors_Automotive_Tools&vxp=mtr#ht_2716wt_982) Or run Vag K= Can/commander through an authentic Hex-Can cable in Dumb Mode.
2. Extract the SKC from the ECU with the walkthrough by IMNUTS ^^ posted up there somewhere^^.
3. If you don't have the SKC from your replacement cluster then you'll have to find someone with a cable to do it on the bench or over OBD with a different interface.
4. You CANNOT CHANGE THE MILEAGE on a used cluster . Unless it has been virginized and has less than 50 miles on it. You can't. //END
5. Once you have the SKC from your ECU (your present Immo systems' SKC) and the one from the replacement cluster you use an AUTHENTIC Ross-Tech cable to perform the adaptation. Don't try with VCDs lite or whatever other VCDS clone software, or try..if it works good! But don't hold your breath.
6. The SKC for the cluster and ECU in a properly working and adapted Immobilizer system in these cars will always be the same. Like I said: the used cluster will acquire the SKC of the old cluster (immo system) when adapted. I have proof of this because I had THREE clusters in my garage that I could swap with zero programming in my old 03' A4. They all initially had their unique SKC for their original system, but after programming they took on the 'original' SKC of my car / cluster/ECU, however you want to think about it.
7. No point in debating #4 because if you've got a virginized cluster you probably have the SKC and shouldn't have a problem. Seriously. Anyone who says they've done it is wack, there is no way around it at all.

You will have little to no luck trying to cheap out here. Sure it's been done by random people with this-or-that cable but there's really no doumentation on what tool they used, where they got it, what procedure they followed etc..
What I just outlined is really the most straight-forward way anyone can explain it and it WILL WORK. If you have problems with your laptop drivers and USB ports etc.. then that's a whole other mess and..well, not really part of the deal.
Or..well, shit- just have someone turn off the Immobilizer.

[mats17]

I'm going to give a big thanks to the help, offers of help, and the amazing advice.
I believe the PIN's are correct. It wasn't too much trouble getting them. I'm sure the login is correct.
I feel I could do the swap..I've certainly logged in to my own Instruments. I know what type VCDS cable I will eventually buy, as I think it would be useful, even to just run diagnostics, add a key or whatever!
But I am going to have to seek Pro help. I'm taking it along at the end of the week somewhere local. I feel confident they can do it.
I can't 100% be sure that I can do it, and I would try..I take risks, but I'd be mental to think I could be one of the lucky ones, as you put it so well Rollerton, those who succeed with this-or-that cable, well they don't give much away! VAGdashCan may possibly virginise and copy my cluster over? It may do some damage though?
I can say that I used VagCommander, with some success.Cross checked with an Edc15 calculator, and examples of Hex code from the internet and I believe I found the checksum part of the code (done in a slightly similar way with the ME7 ECU eeprom) as I put in a previous post. Maybe I could highlight this on a picture of the hex, at least this could be useful to someone in the future? All they'll need is a 'legible' Ecu dump file.

I've thought about turning the Immo Off. But that would have to be a last resort/and temporary one.
I certainly will consider getting a cluster - in fact, pending how everything goes.. I have what seems to be a rare a model number to match, and I bought the only one which I've only seen from searching and phoning around. So to not have a backup cluster/plan, and try it, would be a bit daft.

In fitting the donor cluster, I've only noticed a possible problem/issue with the fuel guage (and miles to empty) reading a lot lower than my cluster does. The donor IS off a similar 1.9 Tdi, which is slightly older. so I'm assuming that using VCDS the settings could be checked .in changing just a byte or two of data can change the miles to empty settings, etc.
But In remembering the jist of a similar issue I read about this a while back..the donor cluster was from a car that used different fuel level sensors - giving off lower millivolt amounts, so the cluster was only geared up to sense those lower powered signals, thus giving a lower reading..Unfortunately, the work around for that, if I remember correctly, wasn't in re-coding, it was from the changing of the 2 sensors (I guess in the actual fuel tank). The lower power outputs of the fuel sensors, If I remember rightly, were about 20-25% of the newer sensors, which roughly, proportionately equates to the difference in the fuel level and miles-to-empty reading of my cluster and the donor cluster.. not that this is likely to be relevant - nor have I measured the millivolts given off to see. Maybe there is an easier way of checking looking at a few measuring blocks in VCDS or something?
Thanks again, I'll keep you posted.

[mats17]

OK Job done.
Main issue now is the fuel level reading is lower than on the original cluster (which was accurate)
I've increased the tank sensor level (Instruments > Adaptation channel 30 ) up to the maximum adjustment, which has made a difference, but it still isn't right. But the cluster change is done.

It would be useful to get a spare cluster perhaps, so If anyone has a cluster model # 8E0 920 981 then please get in touch with me.
Also compatible I am told are the following model numbers: 8E0 920 981x OR 8E0 920 981cx OR 8E0 920 985tx

[mats17]

HI
UPDATE JUNE 26TH 2014
The used cluster is working ok except for 1 persistant fault that hasn't cleared with 5 or 6 attempts.
Initially the Instruments showed 15 faults, all but one have cleared.
I'm hoping that it will eventually clear. I've read of other folk who've had some part or module that has had faults eventually clear.
Whether the faults remain from the parts' previous existence on another vehicle, or appear from some kind of 'shock' or something? I don't know.

Any ideas what to check if this fault remains?
This is the fault:
" 1 Fault Found:
00438 - Fuel Supply Sensor 2 (G169)
30-00 - Open or Short to B+ "

The fuel level guage and the Miles-to-empty is also a bit lower on the New-but-used cluster I now have.

When I temporarily fit my original dash cluster, to compare to, I get a higher fuel level reading and miles-to-empty reading... and I always found the fuel guage and M-t-empty reading pretty accurate.

So far it's the only problem with the Cluster. And the warning light is on pretty much constant now. Even with a 120-140 miles-to-empty range (which on my old, cluster would be something like 170-190 miles-to-empty I'd say, and besides that, the warning doesn't come on until the level gets as low as 80 miles range?!?

I still haven't found out if the original car had different sensors? or if was likely to have had..
I have the VIN number it previously had, but after searching on VIN data search engines..nothing.not a sausage!

[Myst420]

I can look into it once I get home, but I think there's a channel in the cluster that dictates what fuel tank you have. That could be your issue.

Thanks! That'd be cool of you[:)]
I literally just found something on this on tyresmoke forum. Someone had this issue, their car seemed to think It was a quattro version and not the plain 1.9tdi that it actually was. This followed the swap of a DIS. The recommendation was to change look at the coding! (if anyone really needs to read it: http://www.tyresmoke.net/forum/topic/108095-anyone-had-this-fuel-guage-problem/ )

He changed a 1 to 0 (he didn't specify, or even give a clue what he did though!)
So..If I could only get a bit more info on the donor clusters origin, although it was sold as being from a 1.9 tdi, similar to my own! A quattro is something different.

The soft coding My original cluster had, was 0400, and it it was an RB4 D36 cluster.
The soft coding my new/used cluster had / & still has when swapped over is 01400 , and this is a RB4 D35 cluster. Still don't know what difference between the 'D' numbers! I'll find out oneday!
Anyway, so maybe there's s clue there...with the soft coding values?
I've changed very little on the instruments since installing cluster. Just settings like having needles & dials to illuminate only when headlights &lighting are on... ;and the tweaking of the fuel level sensor to allow for the lower fuel level reading -

On A4's (I believe) the sensor level settings range is value 122 up to 136 (128/129 being midwayish!)
Original cluster was on setting 128.
New/used cluster was originally on 122, now bumped up to 136 to compensate. It still gives a slightly low reading.
Anyway, I will investigate tomorrow, as it's almost bedtime!
Any ideas suggestions will be explored and appreciated of course, but after sleep!

Found out from a VIN check, the cluster was from a 2.5tdi quattro....NOT a standard 1.9tdi as I was led to believe.
Anyway, I think I may be on the right path now.
I'm not sure what to change in the code but that should be the answer to the issue!

Any info on this would be great! Shame the Tyresmoke.net page didn't go into more detail.

As I said, my clusters' soft code was 0400, and this new/used cluster is 01400.
Does anyone think that by changing the 1 to a zero would do the trick?

You definitely need to change the soft coding of the new cluster to what your old cluster was. That may solve your issues. I'm looking now for the channel I was referring to.

The soft coding should get you back to normal.

Here (http://wiki.ross-tech.com/wiki/index.php/Audi_A4_(8E)_Instrument_Cluster_(8EC/8ED/8HE)) is the Ross-Tech page about cluster soft coding. The 1 you're seeing is because the car the new cluster came from was an a4 with a smaller fuel tank.

Thanks Myst

Done. Just before you replied, I found this ...http://wiki.ross-tech.com/wiki/index.php/Audi_A4_%288E%29_Instrument_Cluster_%288EC/8ED/8HE%29

I didn't go in depth into it, or investigate channels..just >Recode..
I changed the 01400 to 00400 (coding of my original cluster surprise surprise)
Which has only removed the setting for it being with a smaller fuel tank. I was expecting to have to do more..I assumed that the cluster was expecting a second sensor reading that it won't get, and I was half expecting to have to adjust all this.
Just airbag issue to solve and that's the cluster sorted completely! (airbag light was always an issue though..Airbag Ignitor Upper Limit Exceeded.

Thanks

It's funny. I wouldn't have guessed that the quattro would have a smaller tank, especially a 2.5tdi compared to my 1.9tdi.
Almost half a tank now, 300+ miles to empty, and that is with the tank level set back in the middle of the range at 128. whereas before with the quattro settings, just over 100 miles-to-empty and just above the red!, and that was with the level set at maximum (136). Goes to show the difference 1 digit can make in coding terms!
