Longcranks - really need HELP!!! (beyond HPFP)

Hello All,

details of my car:
335i e92 02/2008 build - 6MT - Premium - Sport - Nav - heated seats, 1400 miles driven

I've had the thing since May. Love the car, but the problems have me going nuts. I had longcranking and rough idling after 500 miles - took it in, and the HPFP was replaced. Drives great for another 700 miles/one month. I take it in @ 1200 miles to swap out the fluids after break-in. Day I get it back, it starts longcranking again. Wait through the weekend, and it longcranks almost 70% of the starts. I drop it off Sunday night. Here's where I'm baffled:

They run the same tests as last time, checking to see if the HPFP is leaking pressure when the car is off. Pressure check comes back fine. All HPFP tests look good. The SA does all of the checks, but finds nothing - no codes. I get the car back last night with no work done. Keep in mind, the first time i took it in, the car did not throw any error codes either; but the HPFP test did show low pressure. I've never had limp modes, loss of power, etc. But this thing is pissing me off...the cranks just feel worse and worse. It kills me every time.

Being ignorant, I've conjured up all sorts of crazy faults...battery, alternator... Injectors? Cylinders? I've tried different gas stations, all premium fuel. I have no clue, but dealership is lost as well. I am not going to bash my dealership, as I do believe they are trying, but they have not resolved the problem. I am taking it back today to see if anything else can be done. Does anyone offer any suggestions?

I really appreciate any/all feedback. thank you

Tell them to keep it until they fix it. Call BMWNA.

I have a feeling you may be two for two on the HPFP. Whatever it is, I hope you get it resolved quickly.
