hello I have a problem with Audi A3 8p 2.0 TDI 170hp 2009. The car started working for 1 minute on idle and turned off, it won't start again. The starter cranks the engine without a problem. Diagnostics does not show any errors. It seems as if there is a delay in the fuel system, the fuel pump in the tank only works when the starter is turned. Maybe you have an idea where to start looking for the problem?
