Disadvantages of the Audi AKE engine
- Most often, owners complain about the rapid wear of the camshaft cams and rockers;
- 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.
