not able to log in to VCDS imobilizer (25) or instrument (17) with pin.

[shurur9]

2002 A4 B6 3.0 Q 6MT

ok..supposedly I have the skc or pin for my car.
I actually have the plastic code key holder.

I cant log in to either address 27 or 17 adresses in vcds

immobilizer 25 address shows nothing in the extra fields
and only Vag bitte address; compt e 17 eingeben it the test fields.

(which tells me to look at address 17?)

instrument 17 address does return the extra codes of the vin and the instrument cluster
and shows it as a RB4 D26..as well as shop code and softcode.

Either address, I cannot get my code to log me in.

I don't know what direction to go.

Q1: is my immobilizer disabled or login disabled?

Q2: did someone change my pin?

Q: what Immobilizer am i looking at 2, 3??

Can someone clue me in as to what i am looking at??


Again,,I could go to VCDS site,,but they just want endless dumps..then tell you what to try and don't tell you why or what they are thinking....and you end up learning nothing.

Try logging in on the ECU to check it as logging in there will tell you if the login was accepted or not. Go to the engine module in VCDS and click on the coding II - 11 button. It will ask for the login code which needs to be 5 digits so add a zero to your SKC. Once you click do it I will tell you if the login was accepted or not and will verify that you are using the correct SKC. Chances are when you were trying to log in to the other modules you weren’t adding a zero before it.

will do the ecu log in.
i did put the zero on front of the pin

Q: should i be able to log in to the immobilizer address 25 and should it be reading out something in the extra fields as soon as i go into the test..before i even try to log in.?

i couldn't get anything on channel 81 either.

that may tell me something.

pin code was a no go.

So does this simply mean that my pin is not correct??

if so, that just means i need to find my current pin!!
It seems odd that It could have been changed..the plastic tag I had was oem because it has the last numbers of my vin on it..

Engine (01) and Instrument (17) are the only two places you can use the SKC as far as I know in the B6.

actually just checking whether my pin code worked.

I plan to upgrade my 2002 (8E0 959 433 T) ccm to the 2003+ (8E0 959 433 BB) ccm in order to make new B7 keys in the very near future.

[shurur9]

ok..sounds like i need to retrieve the correct pin..

Let’s back track.what are you looking to accomplish?You have IMMO 3. Which means the car needs to see a matching immobilizer ID in the ecu,cluster and key in order to start the vehicle.What is your pin? Or how many digits??How was it retrieved???Are you following the Ross tech video for key adaption?

I doubt you’ll have in 25 as this cars immobilizer master is the ecu. 25 module was never used by audi in the states.

I was just making sure I could get in before I started my swap to the newer 2003+ CCM and have some keys made or swap my b6 transponders to some new used B7 transponders (315Khz).

The original Pin/SKC seems to no longer work;
I cannot log into ecu (01)or instruments (17) addresses within VCDS...Thanks IMNUTS!!

NEXT: working on SCK/PIN retrieval via Vag Commander or Vag-Key Login tool.
I need to make sure I purchase the right version of Vag Commander (2.5+???) in order to do the procedure outlined by IMNUTS here: https://sites.google.com/site/imnuts/


I just need to do a little more resarch on which version (2.5+??) Vag Commander to buy
OR
Just give up and buy a Vag-Key login tool instead.

Thanks SO much!!!

If all your doing is swapping CCM you dont need a log in or any of that jazz.Your gonna need to adapt the new keys to the ccm.Which does NOT require skc or pin or anything,unless your trying to program the keys to immobilizer.If that's the case used keys cannot be used as the immobilizer pill is a one shot deal.So used keys will not work until you replace the immo pill.Personally easier to take apart b6 and used b7 keys and carefully swap over original immo pill into b7 key.Just follow this guide.
http://wiki.ross-tech.com/wiki/index...Comfort_System

Also do you have a decrypted dump file from your cluster so I can calculate the skc/pin for your vehicle??

Except that the 2002 CCM is not the same as the 2003+.
It must be upgraded first.

https://blog.fcpeuro.com/how-to-upgr...7-audi-key-fob

"Additionally, If you have a 2002 A4, the comfort control module (CCM) will not work with the the B7 fob. If you wish to do this, you will need to swap in a CCM from a 2003 and up B6."

I also want to be able to perhaps program new virgin keys later...
and I want my damn key code.

The thread was about me getting my key code.
I don't need to justify why.

But I do thank you.

Sorry I dont mean to be rude.But your making my brain hurt,you just overthinking it.What you need to do is go into 46 module Comfort module.Select coding.Copy down the coding.Remove and install new awesome 2003 Comfort module.Go back into 46 ,select coding.Put in the coding you pulled from original module.Or look at the coding break down and find the correct coding for the module based on what options the vehicle has.NOW,you can adapt the key to the comfort module.Comfort module only needs to see a signal from the key.Meaning you need to hit and hold the lock or unlock button.Comfort module does not care about immobilizer id or skc/pin whatever.Its not part of the immobilizer system.Its ecu,cluster and key thats it.ECU is the master for the immobilizer.


On that note I am using B7 keys with my 2003 a4.I also did this on my 2002 a4.Its clean and simple.I bought a new key with a blank.Gave the lock smith my b6 key and 2 b7 keys so he can cut the b7 blank to match.I then adapted to the immobilizer because I purchased a brand new factory key for $65.Adapted to immobilizer and then to ccm.Cake.


Ok well if you want to know the pin/skc/code for the vehicle you need to pull it from the ecu or cluster.Ecu will have it stored on eeprom 95040 should be able to read it in bootmode with some simple software on the bench or you can try reading from cluster via OBD socket with a laptop free software and a simple dongle.This has been covered all you have to do is search.

Also i think you may be making a critical error as in you may be entering the code in the wrong place.Can you confirm in which screen/box are you entering the code into??Also note if the vehicle was ever stolen and all the locks were changed the vehicle will have a new immobilizer identity and a different skc/pin if all that stuff was replaced.

Confirm that you are entering the five digit code into the circled green box and not the red.Please note only Instrument cluster 17 will tell you via prompt if you have the correct code or not.ECU will NOT.

I am Very or quite sure i am entering the code in the right places with the correct number of digits...that i waited the right amount of time to try it again...and again..and again...at the instrument and ecu addresses in VCDS.

as it is now, I Only have one key that works out of two (both start the car..only one works remotely).....but Bought two used B7 type keys as well as the newer (used) CCM already.

I just ordered the VAG-Key login tool as I wasn't comfortable with the eeprom readers out there..far too many stories of things not ending well for my taste.

If I can't get the key code from the VAG-Key login tool.....then something else is very wrong...or disabled..
I suspect that a shop changed the code on me..

[EuroxS4]

Ok whats happens when you enter your 5 digit code in the cluster???Do you get any sort of message??

[shurur9]

need to recall: says wrong code has been entered (or words to that effect) and to turn off car for two minutes before attempting again..

[EuroxS4]

So you have the wrong pin.you either have to read the pin from ecu or cluster.You need other software and a dongle to do it over obd.

Gonna try the vag-key login tool first.
It seems to have a good history.

I was unable to ascertain which version of Vag commander to get.
know 1.4 is a no go..2.5 can't be found..and not sure about 3.6....
also am wary of poking around in the eeprom memory with any "reader."

[EuroxS4]

I have 2.5 and 3.6 and neither are good tools unless you have the original dongle and software,if you use a clone you can brick the cluster.Thats not how I do things.I'm talking about using a laptop with a usb to obd dongle and software to read it all without removing anything.Thats the best way to do it.

ok.."vag-key login" tool is a little hand held reader with obd2 cable...only recovers key code and can also program new/old keys.
It has good reviews for the b6 and vids on youtube

After I am done with it, I can always sell it on ebay.

I'm gonna try that tool first just to get the SKC, but not to do keys.

Thanks a bunch!!

[EuroxS4]

Ok just make sure its reading the pin from the ecu.Cause if its reads the cluster its a good chance it will brick it. They have been known to brick clusters especially on 2002 a4.Youll know when it bricks.Mileage display will show "DeF"

bricked my nexus tablet once...but was easy to fix...
something to look forward to...

cryptomask rb clusters are anything but easy to fix especially if you dont have the right $$$ tools or a backup of the cluster eeprom.Let me know how you make out.

[shurur9]

I just retrieved my SKC/PIn with with the VAG-key login tool and verified it is correct with VCDS eng address 01 login.!!!!


I'm gonna see whether i can get my two keys programmed with it next....
One works now and the other used to until i goofed up the queue in 2007...

I put a new battery in the one that doesn't work.

VCDS shows three keys were once programmed...
I've only ever had 2 keys..both worked until the batteries started to die and i changed out the batteries...

UPDATE:
VAG-key login tool key-learning failed for my car, but keep in mind that i have a 2002-2003- with the older 8E0 959 433T CCM.
2002 had different 2003+ ccm than the other B6 models; so this tool may not have an algorithm around that exception.

tool has been shown to work on 2004 on youtube.
I got my SKC and have VCDS...



8888888888888888888888888
On to VCDS key process to see whether I can liven up both keys, before going on to changing out to the new 8E0 959 433BB CCM and then moving transponders to new B7 style keys....then adapt the new CCM..

2002 A4 B6 3.0 Q 6MT

ok..supposedly I have the skc or pin for my car.
I actually have the plastic code key holder.
.

Actually, most people don't realize this but there are TWO different possible tags that come supplied with the car. If it's the white/clear one that may also have the stereo SAFE pin then that is NOT the SKC /pin for the cluster. THAT is the 'key code' used to get the correct key profile to make a copy of the key blade.
If you have the black plastic tag with a small half a white sticker on it then it could possibly be the SKC for the IMMO system. Those are very uncommon for come by, and were supposed to be removed at the dealer in delivery.

To read the SKC from the B6/B7 cluster you need a tool that can decrypt the Eeprom. There's is some decent explanation in this thread, but the tool I've used for a couple years now is Vageeprom. It DOES work. Cluster must be put in mode 4, SKC read from cluster, then put back in mode 1. THEN you can use the SKC with VagCom to program your keys.

If your moving both transponders from donor key to b7 keys you don’t need the skc.But ok.Hope it all works out

Well my ecu pin was different from the original and I wanted in. So that new issue that presented itself is settled now.
The original thread was just about that...getting my skc/pin.

Then I got asked why and the thread morphed to this..


88888888888888888
1. Because one of my 2 keys transponders may or may not be alive, I think I need to mate those two keys first to the current olde T ccm in order to see whether both keys and/or transponders are viable..or whether I really do only have one good key. I need the skc for that I believe.

That way I will know what I need before going forward in terms of keys...new blanks,,,etc etc..

2. Then I have the older 2002 T ccm and need to install/adapt the newer BB ccm before swapping transponders to b7 keys.
This is were I get lost as one key may end up as a mere valet key in the process..dunno.

I still am looking for documentation on this process of adapting a newer ccm and when to swap the transponders over to the b7 fobs..

I will cut and file the b6 blades for fit to the b7 fobs at my leisure.

I Need to start a new thread when I am ready to start this process.

I think you need to do more research...you seem confused on what key functions pertain to what. the immobilizer transponders have nothing to do with the CCM. That’s why euroxs4 was saying there was no need to get your SKC in his last post. But it’s probably a good idea that you have it because lots of people tend to break the immo pill when trying to release it from the b6 key shell. So in the event that happens you’ll be good when you need to program new ones.

so...I got the ecu skc with a Vag-key login tool.
I was then able to get into ecu login.

The cluster/immo ended up being the oem skc.

So my cluster and ECU were different skc.

i fixed the cluster/immo to match the new ecu skc.

8888888888888888888888888888
Then I "fixed" my faded display on my original cluster/immo with a new one and ran it a while until the immo key reader circuitry crapped out.

Then I got a virginized S4 cluster/immo adapted/mated it to the ECU, then adapted 3 new B6 315kHz (virgin transponders) keys (one new cut blade and two oem blade swaps) to new fobs.
Works fine for starts and mated fine to new cluster/immo.

I am guessing the new B6 key fobs are 2003+, as remote function are not working and not being accepted, but key transponders mated to the new cluster/immo3 just fine.
I will be upgrading CCM next school vacation (substitute teach) to see whether I can get the new keys to adapt to 2003+ CCM, and get my remote door function back as well...or have to get different B6 fobs or transfer the 3 rfid/transponders to my used B7 fobs.

I am not really caring about the B7 style keys anymore.

Thanks ALL.
I know I am a PITA.

[EuroxS4]

When swapping clusters or ecus.You need pin for both current and the module that will be installed in the car in order to match immobilizer.
