HPFP Question

Qunadry · 08-31-2009, 07:47 AM

I have just started having long crank times on occasions, maybe twice a week (2200 miles). Does a long crank initiate a code? I want to bring my car in, but from past experiences, my dealer will do nothing unless a code is detected.

BMW has to solve this problem before engine power cuts off at a bad time and causes an accident or worse costs someone their life.

I hope it does not take a tradegy to get something done.

I would print off a few of the countless stories of long cranks coming before a pump failure and demand it be replaced.

What do you consider as a long crank? It's easy to get carried away and start worrying about it - there are plenty of posts to make you paranoid. I have an occasional (pretty rare actually) "long" crank, 2-3 seconds. But I'm holding out. The car runs great and I would hate to have a HPFP replaced: what if new one is even worse? There is still no fix for this problem and you are taking a chance with a replacement part. Just drive the car as usual, it will not cut off completely (never heard of that). The worst case scenario you will go to limp mode.

CrazyIvan. There are a few stories about the pump going completly and the engine commiting suicide. In that case you put your hazards on, move to the shoulder, and call BMW assist.

Most people claimed even the HPFP failed, the car could still run in limp home mode with the low presure fuel pump pumping. So, you won't be completely stranded unless you are hundred miles away from home.

What month was your car built?

Qunadry · 08-31-2009, 03:01 PM

My car was built in March 2009.

So the car goes into limp mode as you need to accelerate such as merging onto the interstate. Sure hope the semi can get out of the way for you. I just don't hope, I pray it does not someones death before BMW corrects this problem.

on my initial pump...

i had intermittent long cranks and took it in and the pump was replaced before the service engine light was set. The F fault was set in the computer.

on the second pump...

i initially had just a rough idle but have lately been having intermittent long cranks (sunday morning was 7-8 seconds) and have taken it in 3 times (3rd being today). the car is free of faults except for 02A16 (tank ventilation valve fault) so the dealers hands are tied. Ive scheduled a few days in mid september to leave it with them (2 days to allow the pump to de-prime) and am hoping that they see the long crank when they cold start it.

pretty frustrating because i know the pump is going.

the SA told me not to worry as i had the newest pump. i laughed and indicated i had 4 friends that had the remodeled pump fail.

Anyone else finding that its harder to trip the fault now...did they reprogram anything with the pump swap?

I don't really want to replace my stock hpfp until it dies. I had two SES lights on my last tank of gas. I've had 1outta 5 2-3 sec cranks for 5+k miles now. I refilled my tank at a different gas station today and my SES light went away.

Another reason I want to wait until my hpfp completely goes out is the SA tried to charge me for my last visit with that first light due to mods. The are gonna give me a hard time replacing my pump, especially as I do more mods. I figure it just won't crank one day and I'll be late for work, no biggie...well that's what I hope anyways.

if thats all that happens to you then you are lucky. id rather not chance it.

My third HPFP (881) took quite a while to give a fault to replace. For more than 2,000 miles, the long cranks were in the morning, then after it started, it was basically normal all the rest of the day. It finally started giving a check engine and limp mode. So yes, 881's fail, and yes, they take longer to fail after showing the symptoms. At least in my case

singular · 09-01-2009, 03:01 PM

Took mine in recently for an unrelated problem. When he saw my 135 the SA got all excited saying it was his favorite BMW.

He also said that they've seen hardly any problems with 135's. Then he added: "...except the fuel pump".

When I told him that I had heard that had been resolved in the 09's, he smiled, rolled his eyes and said "we'll see".

Not what I wanted to hear.

My135 · 09-01-2009, 04:22 PM

If you have more than 1 HPFP failure, have you thought about may be the root of the problem has nothing to do the the HPFP itself. It may be the fuel presure regulator just like other post said.

I have to agree with you. The problem seems to occur more than once in many cars and not at all in others. This would indicate a problem other than the HPFP.
