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.
