I have a MK5 tdi golf 2.0, whilst im driving the car, the rev needle start to go lower and then the engine cuts out.
I took it to a garage and they said my fuel pump was knacked and I had a new one replaced. Unfortunately that didnt resolve so they fitted a new crank shaft sensor and a relay. They also changed the fuel filter and cleaned my diesel in tank.
The car drove fine for about 15 min and whilst in 3rd gear my rev began lowering and engine cut off.
I realised that when the car is running, it kind of skips a beat sometimes.
Can you advise what problem this can be?
