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...
Coolant migration into the wiring harness. This caused the vehicle to shut down on the interstate creating unsafe condition. Dealer stated this is a known issue with a coolant valve failing. Creates fire hazard by allowing coolant into the electrical system which can then destroy the ecu on the vehicle.
Shifts rough from start through first set of gears. From a standstill, under normal traffic conditions, no matter what setting the car is in, the transmission hunts for the correct gear and roughly shifts from 1-2 or 2-3. This issue was supposed to be settled by the cvt class action but Audi is refusing to repair/replace. I have complained about this issue since 05-06/2014 and for 9 times since until cpo warranty and extended warranty lapsed, now they feel the problem when before they could not and determine the transmission needs replacement for $12,000.
The vehicle is having unintended episodes of acceleration. They occur while stopped or at reduced speeds such as pulling to a stop or parking.
