| Equipment problems |
While driving in traffic, my car dropped into lower gears and stopped moving, and two error codes popped up "gearbox malfunction" and "tpms malfunction". Looking this up online and discussing with my mechanic, this is something happening in a lot of the cars that are this make & model and have the same transmission.
Vehicle flashes a gearbox malfunction warning and most electronics went dead. Vehicle would not accelerate causing me to nearly be rear ended. After turning off car and restarting the vehicle continues to lose power randomly every mile or so. This created very unsafe conditions on a busy freeway. The problem turned out to be a faulty sensor in the transmission. Audi has issued a technical service bulletin on this issue but will not acknowledge the huge safety issue with this defective transmission.
