general problems of the 2012 Audi A6

This needs to be heavily looked into. I see countless reports online and on NHTSA about "coolant" leaking onto components/wiring. Whatever it is, is definitely frying the electrical system. My info screen will state: "transmission malfunction: you can continue driving" and it'll go away a minute later, them beep again with the same message- then beep again- then go away- then come back again. Etc etc etc. I recently a year or so ago got some coolant leak that was dripping on transmission wires below. I've seen this complaint too many times. Audi needs to investigate this issue and if this is a countless issue we need to be issued a proper TSB / recall. . Read more...

I took my vehicle to repair for 2 recalls on 2/22/21, the next day 2/23/21 they called me telling me that I have to pay $ 550. 00 for the repair. According to downtown Audi tech the ecu of my vehicle is defective because they cannot communicate with the vehicle's computer, before taking the vehicle to repair the recalls it was in good condition since I changed the oil and connected my scanner to reset the maintenance message on the vehicle dashboard. This is absurd that they want to scam their customers. Now they want to give me the vehicle without repairing the recalls and with lights on on the dashboard of my vehicle, this is not ethical or professional.
