How can I get my HPFP replaced under warranty

[Zuzu]

Well done Stu..

[pechs2k]

OK. not a HPFP issue. thanks both

[RaihaX]

$350 for HPFP is cheap - no need to worry about warranty!

Yea.. plus you know that no one has messed with your original SW flash. I think if my HPFP ever goes out... I would not want BMW to do it, bc I don't want their laggy SW update.


Bmroxm5 - did you think to also replace the fuel line pressure switch too? I have seen some say that is what BMW does when they do a HPFP. I think the sensor is on the top line going to the pump.



PS: here are my photos of the HPFP's (N54 & N55) seen at the BMW Welt...

Just put my foot down to avoid being cut-off by a douche in a silvia when CEL came on and entered limp mode. pulled over and turned off the engine and waited 5 minutes (put procede into map 0) and restarted and all good.

Is this a HPFP style symptom?

Unfortunately yes.
See how it goes... if you get a long crank in the morning (or after any type of hard driving) then it's a sign your hpfp has approx 6 weeks to live

Because you got a CEL that means you've thrown a code... if this keeps happening now what I'd recommend is clearing all codes with Procede. Removing Procede. Then giving your car a bit of a boot to store a few codes so when you take it to BMW to show them your HPFP is failing they can look at your codes and believe you.

Nope I didn't think about replacing the fuel line pressure switch... Ive spoken to a couple of indie workshops and they haven't mentioned this, and when BMW quoted me they only quoted for HPFP supply + labour so this is the first time I'm hearing about it...

Good point on avoiding the laggy software update

Well thats just great.

So I assume pushing extra boost with these early HPFPs is just a ticking time bomb?

Is this last pump revision the definitive version i.e. not going to f&*k up again?

I admit I haven't searched but have most people in Australia managed to get a warranty replacement or are BMW aus being dicks about this?

Mind you, it was wet and had DSC on. Could traction control have cut the power and forced the engine to enter limp mode to protect the turbos/engine???

It could be various faults, and you wont really know without a proper diagnostic tool.

I had the same symptoms as you under the same conditions, on my 135i running JB3 whilst on my second HPFP..

In my case, It wasn't the HPFP but the "Turbo pressure sensors" from running to much boost.

[RaihaX]

As Joe has said it could be other things aside from HPFP. First thing I would so is see what code you got and if its a misfire I would suggest moving the spark plugs and coil pack to a different cylinder to see if the misfire will move place.

If so it is your spark plugs/cylinder

Yes this is the latest and greatest fuel pump.... until the next one

Nah in all seriousness BMW themselves are pretty confident in this fuel pump, BMW North America usually only have ~1,000 fuel pumps in stock but with this particular HPFP revision they have 27,000+ in stock - prompting speculation there'll be an actuall recall in the US

Hey Stu,

Just to follow up, there is a recall on the HPFP in the USA now, so when you take in your N54 for a scheduled service, your HPFP will be replaced even when it is not presenting any problems.

You were on the money there!

[Taymaishu]

I visited Stu for my oil drop when he was replacing the pump.

Definitely knew what he was doing.

Congrats to BMW for their placement of the HPFP, too (/sarcasm).

If you're getting CELs and out of warranty, have a chat to Stu.

Recall was done at the end of 2010, I don't think BMW Aus is doing a recall yet..

I wonder if it is even worth pro actively replacing with the new 'strong model' my poor neighbour has had 4 HPFP's in 2 years

This happened to me today as the road was uneven while accelerating. Is it anything I should be watching out for? Anyone here knows the code related to HPFP failure? The codes i got were 27B (don't think I got this one right), 2C90, 2CA3, 2C58.

BTW nice write up on the DIY, BMROXM5.

2C90 - Blow off valve, mechanics: Jammed closed
2CA3 - heating lambda sensor of front cat (shearing stress) Bank2
2C58 - Limp mode, Boost pressure control, deactivation: Boost-pressure build-up blocked (Boost-pressure control is deactivated to protect the engine.)

It's likely to be those, what did you use to read the codes?
Not sure if codes are the same between N54 and N55 but I assume so.

I cross referenced with Burger Tuning's N55 codes list, all the same except 2CA3 which read "waste gate activation, line disconnection". Used a CAN Tool to access codes. I have deleted the codes and car is back to normal. Will keep monitoring it to see if these codes come up again.

What is classified as a long morning crank? 2-5 seconds 5-10 seconds?

I'd say 4 seconds plus... you'll know when you hear it, it's rather disconcerting, makes you think 'uh-oh what's going on'

Have a look at You Tube. Search for "BMW 135i HPFP".

There were a couple of videos that show the symptoms getting worse over a few days.
