Hello, does anyone know what this could be? My Audi A2 1.2 TDI started normally, I put it in R and left the garage without any problems. I closed the gate, got in the car and put it in D. I hit the gas and nothing. No gear can be engaged anymore. The car remained in neutral. The gas does not react in any way even in neutral. When I try to engage any speed, nothing happens. Even when the car is not started and I try to shift manually 1-5, I do not hear any physical sounds. What can it be ?
