well I got an 881 a while ago... 5kmi-8kmi, and mine is already going out... much faster this time than the first time. One day it was a 2 sceond crank, next day it was like 10 sec... I know they will fix it, but hope its not just another fairly temporary fix.

jmr_70 · 01-21-2010, 12:04 PM

What? The 881 pump goes out faster than the previous? Mine was just replaced with an 881 a few days ago.....FFFFFFFFFUUUUUUUUUUUUUUUUCCCCCCKKKKKKKKKKK !!!!!!!!!!!

I am encouraged that if nothing else, BMW AG is taking the issue seriously.

Still, the first confirmed 943 failure will probably be depressing.

Are the fuel pumps hard to change (by myself)?

1malt · 01-21-2010, 01:15 PM

I would like to know from the folks that have had the HPFP failures, how close did you follow the original 1200 mile break in period? And did you do another 1200 mile break in period after you replaced th HPFP?
I would say that the HPFP is the week link on the N54 engines and would require another break in.

Any thoughts?

there was an informal poll about this earlier. there didnt seem to be a connection- many with perfect break-ins and HPFP problems, others who flogged their cars and no issues. And vice versa.

I semi-adhered to the break in (might have redlined it a couple times, but generally short shifted and avoided WOT. well, mostly). 10K miles so far, no long cranks.

Thanks, I was just curious, I followed my break-in period fairly close (not perfect, I didn't go over 4krpm at about 600 miles and only a couple times at that, also I didnt hit 6k rpm untill about 1100 miles ) and have had no problems other that not enough time to drive it (only about 1750 mile so far).

PrimoM3 · 01-21-2010, 02:38 PM

I drove my Feb/March build 135i home in April of 2008 at varied engine speeds for 2 hours. I stayed below 5K rpms until I reached 1200 miles. I have 20K miles on the car now and have nver had a long crank. (Knock on wood).

Just hope that a new pump could be the answer those with troubles have been asking for. I also hope this is a permanent fix and will help the resale values for 135i.

Hope I have as good fortune. (knock on wood).

part of me wants to believe that this is the cure for HPFP. One failure wouldn't get to me, but to have a few and start to fear long cranks every time I push the start button- that would blow.

completely unrelated to break-in procedure

DBFIU · 01-21-2010, 03:44 PM

Break in should have nothing to do with 'getting your pump to work right'. If that was the case than every car I ever owned shoulda had a failing pump.

breaking in is a mythical phenomena that people resort to referring to when anything goes bad. Breaking in your motor happens in the first 5 miles of driving, done.

N54 Fuel pumps fail because of other reasons.

agreed with your basic point, but I don't necessarily agree that breaking in does nothing (brakes, etc)

True, there are other things involved with breaking in the overall car. Brakes included, indeed.

As for the engine, the rings, seals, pistons etc... are designed to 'break in' as soon as you turn the car on for the very first time and drive it.

Dr3K0 · 01-21-2010, 04:46 PM

Well, mine got replaced last week (~1600 mi.). I will check the paperwork for tha pump part#.

I had to take the car back cuz it felt slower. Could be a new sorftware update or maybe the pump is different. My SA told me that they reflash everithing and tested the car vs a new one and was the same power level. So I will pick her tomorrow and red line all the way and see if is back to her self or not.

My 2008 135i was broken in crisscrossing the Alps.
Now at 16,000 miles and no HPFP problems.
Sorry to hear you guys are having them.

I don't think it's completely unreasonable to think that a new HPFP might need a little bit of a break in period, considering that it's a piston pump.

Dr3K0 · 01-21-2010, 08:16 PM

Well, 881 here!!!!! Dang. I will have to break it to get the new one

Lets hope the new one fix the problem. I really love my car.

17k first pump. Never over 4k rpm for first 3k miles. Now I run 'er hard.

Also I bought my car with 6 miles on her, so no one was beating her up test driving...

It may well be another shot in the dark. I'll give them the benefit of the doubt until the 943s start breaking. It beats see-no-evil hear-no-evil.
