Disadvantages of the VW AJS engine

  • First of all, this diesel engine is known for the rather modest resource of its turbines.
  • Also, the timing gear mechanism is not very reliable.
  • Often there are leaks on the seals of the tandem pump or unit-injectors.
  • On a long run, shedding of the coating of the cylinder walls is often found.
  • Another weak point of this unit is the air conditioner clutch and generator.
