2008 135i HFFP- My experience aka "Beating the Dead Horse"

[cdub]

I know I am not a frequent poster here on the forum, but I just wanted to share my recent experience with what I believe to be a HFFP issue.

Yesterday after work on the way to the gym I was on a major high traffic road and I downshifted from third to second to turn onto the road the gym is on. As I did this the was a:

1)shutter/hesitation,
2)the engine symbol came on,
3)check engine soon light came on
4)complete loss of power as I rolled to a stop off the side of the road

I attempted to start the car again immediately and the engine stuttered and died.

After calling BMW roadside assistance I tried to start the car again, was successful and pulled the car off to the side into a designated parking area.

The car was then towed to the dealership. I am waiting today to hear from the dealership.

Details on the car: 2008 135i, completely stock, HFFP already replaced once, 19.5K miles. The first replacement was due to hesitation on cold start.

I love the N54, but I am disappointed that BMW has not found a permanent solution to this problem.

I have read all the previous posts about people who had the HFFP go out while driving, but figured that must be the 0.000001% of N54 owners.

When it happened I really began to rethink if the car is safe to drive on an everyday basis. Hesitation on cold start=no big deal. BUT for the car to have a sudden loss of power while traveling at 50mph on a busy major road definitely has me concerned.

Well I'm done venting...I'll see what the dealership has to say.

Has anyone with the "updated" HFFP reported any failures?

Thanks for the reply. Not what I wanted to hear

I haven't had any problems with the HPFP but I just took my car today to the dealer for wastegate rattle. Apparently, I am having recall work on the fuel pump and the injectors.

I have a 11/09 build.
I'll let you know what happens and if they replace the pump or not.

They should not replace it but if they do, I'll leave some feedback.

Thanks. Any feedback would be appreciated. I'm in the Bay Area too...East Bay.

According to Bimmerfile, all issues with the HPFP have been fixed. It is no longer an issue. So, clearly you are confused.

cdub....did you hear any long cranks in the past week or so ? This is a good sign the HPFP is about to die.....

[NihonX]

Whatever pump I had before, I now have the 446 HPFP.

Even though the recall went up to 10/08, it now applies to some newer builds.
I am not sure how far it goes, but mine was due.

The ride feels slightly jerky in stop-and-go traffic, which it was smoother before, but it feels like it has a little more power. It's probably just placebo but who knows. (No Dyno)

If for any reason this pump dies on me, I'm going to be pissed.
My HPFP never had a stutter.

I am now at 55,300 miles.
Mostly highway, of course.

nope.. no long cranks. the only thing I kinda vaguely remember is that very rarely at idle, like at a stop light, the revs would fluctuate a 1-150 rpms...

I thought that was a bit weird, but never thought anything about it.

update...last night I called my dealership to find out the status of my car...

SA: we upgraded injectors, software...(blah, blah, blah)
ME: what was the cause of the problem
SA: well let me look up your records
ME: Was the HFFP replaced?
SA: yes it looks like it...
ME: was that the cause of my problem?
SA: yes it sounds like your car went into limp mode...

Should have gone in for the recall that was posted a few months ago. They would have done the injectors, software, and replaced the HPFP at your leisure. That may have saved you the trouble of getting a tow and all that jazz.
