N55 Fuel Pump Failure

bartles · 07-31-2014, 10:40 AM

So the day has finally arrived. Since I bought the car in February Ive had issues with cold start, decreased power, rough and bouncy idle. Took the car into Schomp BMW and they said the fuel pump is on its way out. 1100$ to replace. Hating life right now!

HPFP or LPFP?

SteveAZ sells LPFP for a good price with step by step instructions.

If HPFP I don't think you N55 guys have a warranty but the part shouldn't be more then $400, they're charging $600 in labor? The N54 HPFP isn't too difficult to replace, couldn't be much different on N55.

Isn't hpfp covered up like 100k miles? Don't feel bad my failed at 28k miles. Lucky for me I got it replaced under warranty

Are you out of warranty? (I guess yes apparently)

Sorry man. Hopefully the replacement is solid.

Its the HPFP. It retails at 1000$, and the best price I found online was $850 so it didn't seem worth it to order the part and have an indy shop do the work.

The N55 got no love on the extended warrantee BMW granted for the fuel pump, only N54's got that, even though pump failure is still clearly an issue with the N55, especially '11s.

Yes I'm out of warrantee cars sitting at 62xxx right now, but I got the guy at the dealer to knock off 10% so thats kinda nice...

I told the dealer I bought my 2011 N55 e92 from, that I would only buy it if he wrote in a condition that he would replace my first hpfp at no cost. He agreed and it's in the contract.

If you are willing to gamble, have it repaired at the dealer. Then, if (and that's a big if) BMW decides to warranty the n55, you might get a reimbursement.

You're an N55 that is pre-03/12....your fuel pump should not be more than $400 with a $50 refundable core charge. If it were post 03/12 then yes....those are a bit more expensive and I'd buy your bad one as I want to play with one of those.

Do the HPFP swap yourself if so inclined. Here is my DIY for it. Your install may differ slightly, but I don't think it will much and the HPFP itself won't.

Edit:
Here's a comparison I did. You can see the differences between the two.
