I found a used 335i I am interested in. My commute is short and HPFP doesn't scare me off considering how much more fun a 335 is compared to a 328 or 325. I read most of this thread and can't find anything regarding how to tell if and how many times the HPFP has been replaced. The Carfax shows service history but only with checking/replacing tires and brakes, is there anyway to tell just by looking at the car itself? I'd assume the BMW dealer doing the work would have these records, but the particular car I'm looking at is at a VW dealership and the records reported on Carfax are from an indy shop.

Edit: It's a 2007 E92 if that makes any difference...
