Disadvantages of the VW AHF engine
- The cause of thrust failures is often in the wedge geometry of the turbine or the damper in the EGR valve;
- Also, at high mileage, valve seats often burn out and compression drops;
- A broken ribbed belt here may end up getting it into the timing and overhaul;
- If your entire sump is in oil, then start looking for leaks from the lower flange of the crankcase ventilation tube;
- The source of the antifreeze leak here is usually a cracked cooling tee.
