problem #3

Feb 252016


  • 54,000 miles


While driving on a Sunday, the car reported transmission issues but it stated we could continue driving. The following day, there were multiple systems failure warnings. This occurred at 54,000 miles and 49 months since purchase. The car began to lose power but was driven back to the dealership. After a lengthy period of time, the service manager reported that "coolant leak in valve N82, coolant migrated into harness and contaminated transmission control unit, causing no comm in pwrtrain can; tsb2033806/7." this repair required replacement of major components and extensive labor costs. The total cost was $9606 and the dealer/Audi voluntarily paid $5391 of the costs

O-ring failure in 2012 A6 3.0 caused the transmission to internally leak fluid causing the electonic system to go bad. All of the following lights came on when issue started. Check engine light, gearbox, mil trac control, mil epc, light airbag mil hi-speed cooling fan mil tire pressure warning light the transmission would not shift, major lack of power to engine. Parking brake would also activate by itself. Instrument panel light up like a X-mas, when I pulled over the car shut off and would not turn back on.
