Struggle Start

Hey Guys,

I bought my 08 335 back in November and have had nothing but problems.
I just put in fuel injectors a week and go(still have to get them programed) and the car was running great. I took a little highway trip yesterday and something happened. I had the cruise set at 73MPH and all of a sudden the RPM's dropped down to 500 and shot back up to 3200 with an engine malfunction warning/ power reduced light. It now has a struggle to start. Here's a video;

Took it to auto zone and the said the warning was a crank shaft sensor malfunction? I've watched a few videos and think it might be the fuel pump. Anybody had to deal with this agony on their N54 before? Any help is much appreciated.

Thanks,
Ryan

Crank shaft sensor malfunction was the code that auto zone told me. Interesting thing is, I just drove it to the gas station(still having the engine malfunction) filled it up and the issue stopped. I was a little above a quarter of a tank before I filled up. ImGone 92 I too am thinking that... was that a heavy hit on the wallet?

We have hpfp covered until 120k miles. They won't replace it unless you have hpfp codes and claim to have 45 second start times

Hopefully BMW's computers read that code... They're booked for the next two weeks so I hope it last

Yeah, thanks to the 'Customer Care Package', aka 'We fucked up so bad we cannot afford to call this a recall, so let's spin it and call it something else that makes it seem we are doing something extra for customers'

I had to wait 4 days for them to run a simple diagnostic on my car. And I had the priveledge of driving one of their awesome rentals, if you're familiar, it's called a Kia Soul. It came equipped with complementary vomit on the door panel as a gesture of good will on their part.

It was the HPFP. They covered it under warranty. Appreciate the help...BMW service department gets a lot of business, as a owner I can understand why, so it took me two weeks to get it in. Had to drive around with it like that for that long.
