When I suggested "charge pipe" I was also thinking about HPFP issue but decided not to suggest it because there were much less reported HPFP issues with 1Ms, I recall 2 or 3 cases mentioned in this Forum. Charge pipe on the other hand is a very common issue and it seems to be it is a question of "when" rather than "if" it will crack/pop or not. Blame goes to higher boost 1M engine map plus the overboost function combined with a bad design and material. So, I personally am still undecided about the HPFP being classified as a common 1M issue. What you guys think?
