Hello from Romania!
Today our A2 1.2TDi died in the middle of the city at a red light. I've seen that the gear indicator in the cluster was indicating 2nd gear when I've stopped and waiting for the green light. After I ve released the brake the engine has turned off. I've turned off the ignition, crank it up again and everything was normal. For the last few days in the morning, when I open the driver door I can't hear the pressure pump. It starts after turning on the engine. It shows on the cluster that the door is open so it is not door switch related. I ve connected my vcds and I attach the faults. I've erased them run the car, it didn't died again and no errors were shown. I blame the pressure accumulator but what do you think? I can do 3-4 shifts within the pump starts making pressure. I've also looked at channel 20 in measuring blocks. with the engine off when g270 - pressure switch is around 2.6V it starts pumping until it reaches 3.2V. If the car is in stop it keeps the pressure but if I let it in other levier positions (with the engine off like I said) the value slowly decreases until in the end the pump start again.
