Disadvantages of the Audi CAGA engine

  • The life of piezo injectors here is highly dependent on the quality of the fuel used.
  • Until 2009, these diesels suffered from an oil pump hex problem.
  • Also, such motors are very fond of pressing oil from under the plastic valve cover.
  • The timing belt is replaced at a mileage of 180,000 km, when it breaks, the valves bend.
  • After 200,000 km, a lot of problems can throw up a particulate filter and an EGR valve.
