Hello all!

My name is Brett. I own a 2015 Audi A3 8V Quattro that I've been modifying.

I noticed how engaged your members were in helping address issues, and I'm hoping to have some help too.

I am having some coding issues in my computer that's throwing fault codes and I hope somebody can help me.

Thank you!

[BMoneyBrett]

@dv52, especially your help with hex and long coding. I hope you or someone can help me.

Welcome to the forum

First thing you need to do is post your full autoscan.
Do you (or did you) have a factory fitted amplifier?
What have you done (or tried to do) with coding or adaptation changes to these modules?
Do you have an autoscan from before you started playing around?
If so post that also.

I was able to remove the code for 19. I tried modifying the Bang and Olufsen module in OBD11.

My only issue now is 09, central electronics.

I don't have VCDS, only OBD11. How would I scan and post a full scan?

I have the factory Bang and Olufsen sound system with an aftermarket subwoofer and aftermarket subwoofer amplifier.

I'm also getting P003000 - O2 Sensor Heater Contr. Circ.(Bank1(1)Sensor after replacing both O2 sensors because I got a new high flow cat with downpipe. Not sure why that's faulting.

[kamold]

Ah my apologies.
Makes it a little more difficult but not impossible.
A vcds autoscan if you can get one will make it easier.

Do you know what you were changing before you had the BCM incorrectly coded issue? Just generally? Might make it easier to debug.

Also you could compare you coding to a similarly specced vehicle reference scan in the Ross tech forums (don't change anything, just try and find one to compare against).

Thank you for your kindness and swift responses. I can borrow my friends vcds tool for a complete scan and post it here in 2 days.

I've changed so many modules that I'm unsure what I could have messed up in 09.

I could try and find a similar spec vehicle reference scan too.

The O2 Sensor is bugging me though. That's the main cause of my concern.
