1.4TDI PD
Well-known member
Hello i have an audi 2.5TDI V6 and the problem is that when the car sits for more then an hour or so after it was driven cranks for around 4 seconds and then it starts. When the the engine is cold it starts withouth a problem it was -10°C and it started without a single problem the engine uses a VP44 injection pump wich is simillar to the VP37 that is used on the 1.9TDI i checked the timing with VCDS and it"s spot on could it be the coolant temprature sensor or something else.
