[09Monaco335i]

My two cents... I took my car in for service this week. For the past month or so I noticed it starting/cranking slowly. At one point the "service engine soon" light went on after the car failed to start at first.

They performed a software update. They said they tested my HPFP and said it was fine. They said it was a "newer" HPFP and didn't need to be replaced.

2009 E90 Build date March 2009 335i xDrive ~19K miles

Anyway, got my car back and it starts right up now. So far no problems.

I did not receive a service recall letter.

Good for you,but did not you notice that your car is slower and sounds louder ?

The new update will make the engine sound louder if you havent had an update in awhile.

in regards to my car behaving better... its too early to tell but certain things such as...

MPG indicator seems to be where it was a year ago (i've lost about 3mpg since a year ago )

engine sounds different... before it was alot of tapping now it sounds more electronic ( all related to the injectors )

performance too tough to tell though it does seem responsive... again too early to tell, ice and low temps doesnt help either

Just dropped mine off this morning for the hpfp/software update (and hopefully the vanos solenoid replacement....not recall related). Just so scared, sitting on pins/needles waiting to hear back from them! :insert nail-biting smiley: (need one of those)

Didn't have the recall letter either. They'll pull it up in the system as to what needs to be replaced.

Any BMW forum search will show the same HPFP failures worldwide, not just in the U.S.

I really wish people would read through this thread along with maybe 999 out of the other 1000 threads about this before they post this in here. Or just read the FAQ.

After receiving the recall letter, I had 4 new injectors and fuel pump (933) replaced on my 07 335xi. The most noticeable difference is the smoother idle.

[DASHOCKER]

I'm curious if this software update is actually a "new" update? 1 month so far on this new pump & update and the car has been flawless.

[Stock-ish]

I received a call (no letter) from Ganley BMW to tell me my car (07 335i 6mt, ?? build date) was due for a software update late last year. Just got around to taking it in last week and asked if this HPFP recall had anything to do with my car. They said no and that this software update was "probably just for something behind the scenes, you won't notice any difference". Since this wasn't exactly an intelligent response, I looked up the number on here (SIB130910) only to find out that it's the HPFP software update.

Prior to this update, I would hear the low-pressure pump run when I "woke up" the car. Now I hear a much louder noise that I can only assume is the HPFP running when the car "wakes up". I assume the low pressure pump is running too, but is drowned out by the noise of what I assume is the the HPFP. In all honesty, it sounds like my sump pump.

Little history: I bought the car used w/ 48k miles and have had no issues with long cranks, etc. Service history shows that the original owner had the HPFP replaced at ~20K miles. So far so good since I've had it, but we shall see. Thankfully the dealer has confirmed my HPFP is covered under the warranty extension if it ever does die.

Anyone else get the new pump sounds?

Yes, the sound of the pump(s) priming is much more pronounced than before.

What is this pump priming? I had the recall done and I do not hear anything. I just notice my car being alot smoother during idle.

The motorized sound that you hear when you unlock the car is the sound of the pumps priming with fuel. I guess the HPFP & LPFP need to filled with fuel before a cold start?

RaZCal,

I believe Shocker is referring to the "first" software adjustment which allows the car to prime the HPFP when the door is unlocked. It's loud; I mean really loud.

You had the HPFP recall which changes "I believe" the priming step too. Here's what I noted:

a) The car only primes the HPFP when the car comes out of sleep mode (not just unlocking the door)

b) So wait 15 minutes away from the car, then go unlock the door and move your ear next to the seat...you'll hear it prime. It's like fives times quieter than the original prime noise.

c) I also noted the engine may not roll-over as fast because it is not always priming when the door unlocks. You may see a slight delay.

These are just observations, I called my SA to verify what I noted. When he gets back to me, I'll post. I actually posted in the HPFP Sticky because I thought my car quit priming. I was never away from the car for 15 minutes when I started it after the install....funny how that stuff goes.....

[GRLPWR]

Well, got mine back yesterday, new hpfp, software update. Can't tell any difference w/anything - performance, sound, etc.

However, I did get a new to-do list: lpfp, valve cover gasket, spark plugs, swap o2 sensors!

[OnlyTruth]

Went for service today , no recalls listed in BMW system on my 2008 335.....

I even showed a printout of both SI posted here, and SA highlighted the part that says the final auction is taken upon DCSnet Dealer Communication System.

I did have vanos and one fuel pump previously replaced and reprogrammed though.

[Just a 3]

I got the recall done (car is still with the dealer) - injectors changed, HPFP replaced (933 - they didn't have 466) and software programmed. Will be picking up later today, or tomorrow - will post my review of how the car drives, and any differences.

Picked up the car in the evening - no difference from before - got teh 933 pump, so will wait it out till it screws up

[marius]

Just returned from service. New pump is 13-51-7-616-446 97, and they replaced injector #6. No reprogramming.

[The Ringer]

I have 45,000 miles, original pump, and no issues. My "Check Engine Soon" light came on 3 weeks ago, and a week later my recall letter showed up. So, I made the 2.5 hour drive to Motorwerks BMW in Bloomington, MN. I just got the car back after it spent a week at the dealership, and here are the results.

For the Recall:
-Replaced injectors 2, 3, 4, 5, and 6 (PN: 13-53-7-585-261).
-Installed new seal on cylinder #1 (PN: 13-53-7-584-315).
-Replaced high pressure pump and low pressure sensor (PNs: 13-51-7-616-446 and 13-53-7-614-317 respectively).
-Updated vehicle software to the latest version.

For the Check Engine Soon Light:
-Replaced DTML (Leak Diagnosis) Pump (PN: 16-13-7-193-479).
-Replaced DTML Pump Wiring (Cable Connector) (PN: 61-13-8-353-746).

Random Fixes:
-I complained of rear brake squeal, and when picked up my car they had replaced both rear brake pads and and sensors.
-I asked for a courtesy inspection because I live so far away from the closest BMW dealership and I am at 45,000 miles. When I picked up the car, they said everything was fine, except my wiper blades, which they replaced.

Overall, I'm extremely happy with my experience at Motorwerks BMW in Bloomington, MN, and how they handled the recall issue and other issues I had.

As noted on the previous page, I just had my car in for the recall and a couple other issues. I got my car back on Friday, and this morning I went out to start it for only the 5th or 6th time since it's been home, and it really struggled to turn over. Before the recall service was performed, I never had a problem, but today it took three attempts/pushes of the "Start" button before it finally fired. Of course, I should mention that the air temperature when I tried to start it was -29 degrees F, but it's been pretty cold here a few times this winter and I never had a problem. I hope this isn't the start of something bad....

Yikes - if I read your post right the temp was minus 29?? My sympathy is with your car - if I was that cold it would take a hell of a lot more than 3 tries to get me to turn over!

Seriously, I wouldn't worry too much at this point. I suspect that cold weather alone plays a major part in your starting issues. Others more technically adept than I may chime in, but I wouldn't be surprised to learn that the BMW software won't let the car start until a certain level of oil pressure is attained. Are you using oil designed for the temps you've got in MN?

Rick

[The Ringer]

You read it right: minus 29 degrees (and that was when I started my car--it was minus 32 degrees when I woke up a couple hours before that).

Regardless of the temperature, my wife's 2007 Toyota RAV4 starts with no issues in the same temperatures. No special oil in either of them. Could it be something to do with the difference in engines? Does direct injection/high compression/forced induction make any difference in how well a car starts at cold temperatures?

Anyhow...like I said before, I would be happier if it was the cold causing the problems, and not the results of the recall service.

-The Ringer

[Potty_Pants]

Well my car is going back to the shop.

a few days after the injector, pump and whatever else they did...

my first start in the morning (temp around 25-30) the engine would rev from 800-1500-800-1500-800-1500... until i shut the car down. The 2nd start it ran fine w/o any problems.

Now two weeks later Temp is around 18 (garage kept) and it did it for 4 starts , I tried to give additional gas and the gas pedal didnt provide any additional gas to the engine. The 5th try i immediately gave the car gas to 2k and the 800-1500-800-1500 stopped. however the check engine light was on in the dash.

guess its going back

I am not so sure it is all that "new". If you have had a software update in the last few months then when you take the car in for the recall you may get a pump. If the software were "new"(more current than few months ago) then it would be my guess that you would receive the newer version to try before they replaced the pump. Does that reasoning make sense?

Not sure if it does but in about 1 week I wont worry as much cuz i am going to be in M6 land!!
