Disadvantages of the Audi AVG engine

  • The cause of thrust failures is most often pollution and wedge geometry of the turbine.
  • A clogged EGR valve may also be the culprit for unstable engine operation.
  • If you have an entire sump in oil, carefully inspect the lower flange of the crankcase ventilation tube.
  • The source of the antifreeze leak here is usually a plastic cooling tee.
  • At high mileage, valve seat burnout and loss of compression are common.
