So I gather the primary problem with the N54 is the HPFP.
Coming from a S65 M3 I am glad it is not like the connecting rod bearing clearance issues that cause your motor to implode.
I would rather have a bad fuel pump that can be fixed, than total engine destruction!
Is this the most major problem with the N54?
