[TOPSTRIKAA]

So I was recently receiving long starts. And I believe it is the Hpfp that is also what my mechanic told me and to replace it.
These are the codes I got on bimmer link.

11B401
11A401
No check engine. But car does shake vigorously. Gives a drivetrain malfunction if on idle for too long on P (Park). (Guessing) bc of the fuel pump tweaking at low rpm's.

I see there are two kinds. One for 600-800 dollars and one for 250. Now like every other car guy I want to pay for the 250 one lol. I know being that my car is a 2011 it uses the old one. But there is a newer one with an "adapter" Wondering if I can put the newer one on the older f10. Either way I'm gonna spend the money. Just want to know if I can buy the smaller 250 dollar one. Thanks
