my SA called me just a little while ago as my car was in for its 3rd HPFP (so i thought). They said the fuel pump passed all the tests but the had to update the software. lets hop this fixes it as this would be the 3rd pump and im just under 18000 miles.

2007 335i  [0.00]
when I finally got my cold start issue fixed (at seattle bmw after it became clear tha bellevue bmw was worthless for someone who gives a s#!t like me) they gave me a new model of fuel pump, different from the new one I got early in 2009. This is in conjunction with the latest software.

cold start issue is gone. They also fixed some other little things that should have been done while it was at bellevue bmw, such as calibrate the injectors for the new dme that I had installed in december. Basically I have had every little issue that could pop up happen within the last year and now am finally all up to date and I feel like the car is solid once again.

If someone can give me an example of an old part number for a hpfp I can see if the number i have here is comparable and I will post it for you guys. I was told that the 2010 fuel pump has been reworked and should be the magic fix, but you guys gotta ask for it.

Funny, my service advisor still hasn't called me to tell me that he can resolve my cold start issue. It started happening once I got my new DME and the new software (maybe it has to be in conjunction with the new pump, who knows? Anyways that was three months ago and he could only tell me it was a software issue and they were working on it. No one is accountable, even when I complained to Customer service, they gave me the whole, "well, what can we do about it" thing. Not saying its just bmw, but when you are dealing with a large corporation, it is difficult to get someone to take accountability for the company they represent.

Did GIAC get this figured out yet?

I had the same procedure done to my car. They only updated my software to version 37 and didn't put in a new pump. The car is fine now, my cranks are not the quickest but it starts everytime.

Here's my biggest issue. I run a JB3 pre and post version 37 software updates. Before my boost guage would hit 16-17 psi and post software update, I don't see anything above 12 psi. Anyone having similar issues?

Not in my case. Giac still has not came up with a file for my car. Been almost 3 weeks now. Wish I knew what the hold up is.

You may want to contact GIAC directly in case you're still waiting on your update.

Which version of the JB3 are you running? I had the 2.0 in my car for several weeks (also BMW software 37.0) and had no issue, boost and power aplenty.

I've tried 2.0 24 Ohm, 2.0 18 Ohm, and 1.4. All 3 gave me this issue.

Alright - then you should contact Terry@BMS directly, he's always very helpful. There's already another thread about this problem here (JB3 2.0 BMW Software Update Problems?), and I've also read on N54Tech that there are others with the same issue. I'm sure Terry will be able to sort it out, maybe Mike@N54Tuning.com can also shed some light on this issue.

It could be that your software version is still different from mine as I don't seem to have that issue in spite of the update. But then I'm from Europe...

Also, if a problem is software based, everyone with that version of software would be affected. Not everybody that owns a 335i has had their HPFP replaced.
PLUS 400!!!!!

The pumps are junk I had mine replaced 2 weeks ago with the software. I am already getting some long cranks again and rough idles, which is probably due to injectors and spark plugs. I am just getting disappointed with the N54. I really loved my S54 just didn't make enough power and HPF turbo kits for the m3 are a little out of my price range.

BMW should really step up and extend the warranty for the HPFP to 100,000 miles. Many/most BMW owners will not migrate up and will purchase another car from BMW or a competitor for most of their life. Once massive screw up like this HPFP issue could really turn them against the company.

actually I think they've done better than that and upped the HPFP warranty to over 100k correct???



also, I was told about this "fix" several weeks ago by a tech that just left training in Atlantic City. He basically laughed when he told me since he also knew it was a bullshit fix for a mechanical problem.

That was done about six months ago.

Sniz....my $.02 on the issue (based on my own understanding of the Lemon Laws) is that if BMW can extend the amount of times a car comes into the shop for an identical problem by NOT stating the problem to require the same fix, then the whole "3 times a charm" for a Lemon goes out the window. I have a friend on here from VA that got BMW to give him a new car. I went in for my 2nd Long Crank and 2nd SES light within 9K miles. Trust me bro, I was pissed when they told me it wasn't the HPFP and the software just needed to be updated. Now I'm still getting Long Cranks, will prolly get the SES light again soon, and when I birng it in...they'll replace my HPFP and only say it's my 2nd time in for HPFP related issues, when I too could be in a new car. I'm not anti-BMW or anything, dont get me wrong, I understand business is business....but dont find loopholes for laws at the expense of me having to bring my car in every 3K miles for the same shit. At this rate I'll have had my car in for HPFP 3 times before even getting my first "regularly scheduled" Oil Change.

I had 3 trips to the dealer here in Austin for HPFP...3rd trip fixed it for good, no problems since. The problem waited until I had somewhere around 14K miles first time around, and after the new part number was installed about 5K miles ago, I've not had any issues. Dealer always had a loaner car for me (a new 5-series, even!) and always got me in within a day or two. In all 3 instances, I only experienced the SES light and one time I had the long-crank thing, but never got stranded.

And that's for both types of ECU's? (MSD80 and 81)? Mr. 5 with an MSD80 ECU already said above (post 15) that he got his car flashed by the dealer and then GIAC managed to flash it no problem.

I would assume so, yes. Austin told me that the problem they had seemed not to affect the earlier MSD80 ECUs but only the MSD81 which I have, which is why Craig could run his car with the stage 2 flash in spite of being updated.
