I understand your pain, particularly because at
2 ~ 5% yearly failure rate from our HPFP, that is 100% certainty that we will have an HPFP catastrophic failure by the time you reach 150,000 miles (I know most TDi owners keep their cars up to that number of miles, if not more), not a heartwarming thought at $6,000 ~ $10,000 per fix.
The interesting thing is that GM, of all North American car makers the only one to introduce a TDi car, spurned our
Bosch CP4.1 and adopted an older design
Bosch CP1H. I guess they learned a lesson from counting all our VW HPFP failures since 2009.
Now, if they could only produce an Impala TDi, I would give up my Passat in a heartbeat.
