I have 08 535i, N54 engine. I got my HPFP replaced two times 
Anyway, I'm going to trade my car and thinking about new F10. According to e90post, there have been reports of HPFP failures with N55 :thumbsdown: Because of the reason, maybe I will buy 550i.
I believe N54 has twin turbo, N55 has one single turbo and N63 has twin turbo. I have never heard N63 HPFP issue. Can anyone explain why?

I said there have been reports of HPFP failures with N55 engine from e90post(3series). So who knows maybe new 535i will have the same problem
My question was N63 engine has the twin turbo as N54 but never heard HPFP issue
