  • Next in popularity are the problems of the electronically controlled injection pump Bosch VP44;
  • The vane pump, which pumps fuel from the tank, is also not very reliable;
  • Oil often oozes from under the valve cover and at the joints of the block with a sump or cylinder head;
  • The weak points here also include pressure reducing valves and a viscous coupling bearing.
