I have a 2003 Volkswagen Passat with 77,650 miles with problems with the oilpump and engine problems that is unknown. The automobile will stall not start it hasn't been driven in over 6 months due to the rattling noise in the engine and I believe slugged is build up in the engine but since then I have replaced two oilpumps in the vehicle and the sensors. Engine oil pressure failure and defective coils on each cylinder.
