My ecu 8e0907551b has a burn. See pics help needed in rewiring.

**ufkenedy** · 03-01-2018 11:48 PM

Ok guys how's everyone doing.

I traced a problem of my audi a4 b6 2002 3.0 Quattro to a burnt line inside my ecu. I am trying to rewire since no component is burnt just the 2 lines from the clip cables or whatever you call it.

See pictures.

I am trying to rewire so as to feed or link or connect burnt part to there correct paths. But i will need pictures so as to verify and solder to solve my issues. Trying to save cost here all help needed. If you have inputs or you've had similar burn or damage or just pictures of this type of ecu or other type of same model. It will do. 20180302_083819.jpg 20180302_083814.jpg 20180302_083810.jpg 20180302_083802.jpg 20180302_083751.jpg 20180302_083738.jpg 20180302_083724.jpg 20180302_083706.jpg thanks

I’ve got a spare B6 3.0 ECU I could let you have cheap.

If you’ve got burnt tracks, the chances are there’ll be component damage, too. They don’t have to display burn marks to be fried.

Ok. Can you get it to me in nigeria?

But if you can send a picture of the circuit board it will go a long way

Huh? As in crack the ECU open to photograph the circuit board??

**DarkoNova** · 03-02-2018 04:16 AM

I have a spare 3.0 ecu at home that I was going to use to for tuning. If nobody gets a pic, I'll try to get a pic for you.

Though, I do agree, I think a new ecu would be better.

Ebay is not a bad call for a used ECU. This one is listed for £48 and shipping is around £10. All for about $79 US. Lots of used ECU's to be had. You will need to match the SKC old to new. A read of the EEprom should do it. Also, it would be good to root cause the failure. Was it a component on the ECU or something it connected to.

The issue is my a/c blower stopped working and i get epc light too. Its the ecu. Theres a burn from the picture above. That's why i want to repair first but i guess I'll order on ebay.

Meanwhile i have to ask. When i get a new ecu of same part number will i just install and drive straight away or i have to copy coding from old to new only.

I don't know what skc or eeprom is. But i have access to only vas5054a

SKC is the secret key code. Lots of ways to do this.

I just did my manually last week using a hex editor a few programs I downloaded a $10 cable and an old PC.

**ufkenedy** · 03-03-2018 01:41 PM

I don't need skc i guess. Mine's a 2001 model as seen on the seat belt

guessing you've got at least one chip fried, and the only place to get many of those is.. in another ecu.

What is the pin number of the smoked trace.

Pin 49 and pin 68

I had the proper size bits at work and managed to open my ECU. Got some pics but for some reason they're not uploading to the site.

I don't want to use Photobucket because they suck now.

I guess I'll try uploading them on my computer when I get home from work.

Wow, even on my computer it's not uploading the pictures to the forum.

Had to use a third party site. ANYWAY, hope these are helpful:

If you need better pictures, let me know.

Ok so i soldered a cable strand and with the help of the picture.
Though i must confess despite the fact that they are same ecu, the circuit paths are slightly different so its not apple for Apple. But i tried and soldered and upon testing my epc light went off and my a/c blower worked.

But after few starts and stops same problem surfaced.

I'll remove to check in the morning. Maybe this time a component is fried but I'll check

I believe I have an AVK 3.0, and it's an 04 model year.

I don't know if the 02 3.0 was an AVK as well or if it was different.

I don't know if that even matters.

The ecu number I have is 8E0909559L.

I'm not sure what the difference is between mine and yours.

Sorry it didn't fix your problems.

Are you kidding :D of course it solved the problem.

i removed and checked and i saw a cut strand. i used a thicker strand and so faR my epc light is off and car runs smooth without hesitation. no more limp mode. although my A/C blower/Fan isn't working yet but i can live with it for now.

i will check other stuffs and work towards getting another ECU.
Thanks

**DarkoNova** · 03-07-2018 12:59 AM

Oh, well then I'm glad it helped, lol.

**ufkenedy** · 03-07-2018 03:13 AM

I have my immobilizer light flashing. I disconnected battery impromptu and now the immob keeps flashing and once car starts, it dies. What can i do to make light go away? Anyone?

**DarkoNova** · 03-07-2018 03:50 AM

Sounds like a problem with the keyfob. Starting and dying after a second is usually due to immobilizer. I don't think that would happen if the battery in the key fob died, but I could be wrong.

**ufkenedy** · 03-07-2018 04:44 AM

I read its got to do with anti theft

You're going to need to start a go-fund-me if you plan to maintain this vehicle with a zero dollar maintenance budget. The fact you were able to rework a couple of burnt traces and solve a running issue, even temporarily, is nothing short of a miracle. You need to work backwards and figure out what component is connected to the pins of that burnt trace and investigate or you'll just be back in the same situation.

As far as the immobilizer issue, I'd jump straight to disabling it. You'll need a blue cable and follow this http://nefariousmotorsports.com/foru...c=5068.0title= Even if you get a new ecu, you'll still need to deal with the immobilizer unless you get one that already has it disabled.

I'm grateful bro thanks. I'll do as said. I actually want to fix all faults and get some spares then sell and get a better audi.
