Disadvantages of the Audi CDHB engine

  • The whole life of the owner of a car with such an engine is spent in the fight against oil consumption.
  • The manufacturer has released several piston options and often replacing them helps.
  • Due to the constant oil fumes, the insides of the motor are quickly overgrown with soot.
  • One of the solutions to the oil burner problem is the purchase of forged pistons.
  • There is also a very short-lived timing chain, sometimes it stretches to 100,000 km.
  • Ignition coils, water pump, injection pump are not the highest resource.
