ecu and tcu failure

The most problematic vehicle ever! First, both fans stopped working and car almost overheated on a hot sunny day. Then then problem after problem. Oil leaks, power steering hose leak, coolant leak, electronic issues (airbag light just turned on and won't clear), electronic e-brake light turned on (still worked).

Then the most annoying issue. ECU damage due to corrosion. VW engineers decided it was a good idea to have the water runoff from the windshield run down close to where the ECU and wiring harness sits. Water got inside and destroyed the ECU, the TCM 12v line, and other issues that even my mechanic couldn't solve. This costed $300 to fix which required a replacement used unit and a dealer reprogramming. Sold the car soon after. Please stay away from Audi vehicles.
