Did you unplug the ECU's yet and see if EPC light goes out in cluster?

Are you going to configure VCDS with your own WSC. tester # and importer # and then login + recode the modules to default them yet?

Just attempted to recode both ecu 1 and 2, no difference. EPC light remains.

Also, these ECUs do not need a login for recode and if they did, I would need a security access key.

EPC light should not come on when ecu's are unplugged.

here is how the light is functioning. The first section is with the ecus plugged in and the second is with them unplugged.

What happens if you undo what you did?

Do you still have the old controller you replaced?

Can you take all engine controllers apart, label them carefully and ref location and post pictures of each ECU can and board in forum?

I did not replace any controllers. The only thing which was done was accidentally swap the 2 controllers when checking the wiring. Vehicle did not start, so I swapped them back.

We were told by the dealer that there were no updates available for the vehicle.

alright, I just had to sit here and reread everything to comprehend what you are getting at.

Current software version on the ECMs is 4070, but it should be updated to 8486 to be current, no?

Correct me if I am wrong or tell me if I am missing something.

Thanks

Don't you see the links to VAG's publicly required and disseminated website as required by the Clean air act for a firmware level Cal ID and CVN?

Much does not get by you does it?

Do the updates indicate a DEFECT?

:rolleyes:

Did you let the Audi dealer agents know & that allegedly stated in opposition, that they don't know shit?

Did you further let Audi know, a second telltale ( EPC ) in regards to functions tied to a clean air act device or AECD, well are allegedly illegal, so it's their responsibility to fix it and since should be working with continuity of a check engine MIL if illuminates and should display a DTC if it does illuminate during operational conditions of engine running?

Great questions to ask huh?

Oh that pesky useful life warranty again?

I'm just getting/giving information 2nd hand at this point. I had the person dealing directly with Audi read what you are getting at and we discussed what it all means....I think we have something to work on now.

I appreciate your clarification. Very helpful.
