Disadvantages, breakdowns and problems of R2AA
The most famous problem is the rise in oil level after burning a soot.
Often there is a burnout of the sealing washers under the nozzles with a breakthrough of gases
The timing chain can stretch to a mileage of 100 thousand km, and when the valve jumps, it bends
Weaknesses also include the SCV valve in the injection pump and the position sensor in the turbine
Once every 100 km, here you need to adjust the valves using special screws
