I have a 2003 TT Quattro 225 hp. my check engine light came on about 3 weeks after I just had it sevice for it's 40,000 miles. I took it to a place that hooked it up to their machine and it came back with that they found one present in memory. Code #P3129 refers to unknown fault. They cleared the code from the ECU's memory. I then drove it for a day and a half and the check engine light came back on again. Took it down there again. Said that they same code came back. They don't know what that code is. Said they tried looking it up and asking around and they have no idea. How about any of you? The place I bought it is 200 + miles away they are the closest Audi dealer so I was hoping to save the drive. Please Help
Thanks, Heidi

 

I've seen a huge list of codes, never seen that one. Sure you're copying it correctly/completely?

Heres a list of people with vag-com capabilities. http://www.steve-hall.com/cgi-bin/VAG-Locator.pl Maybe someone's closer than 200 miles. I know for NY, theres someone in just about every big college town, so trouble code reading is pretty easy to be had. I live nowhere near a college, and have a cable, so I have the inbetween covered too ; )
