I'm really careful with the mpgs....I did notice that after I got a software update (old one now, something like 35.4), and found it disappointing.

Then, 3 mos. later they replaced my VANOS intake solenoid and the mpgs seemed to be restored. If there's no relationship between the VANOS and mpgs, then it must have been something else...

It was the most embarrassing and ridiculous proof that the car was broken that I've ever seen.

Yet when I took it into the dealer, they said they could not do anything about it because there were no codes. That's not their fault; I don't expect them to work on the car if they're not getting reimbursed by BMW, but c'mon.... This went on for a month until finally one day it successfully went into limp mode. At that point, I drove straight to the dealer and they took care of it. The software threshold has definitely been changed. I have no doubt.

I am not sayoing this to be ficitious(I think that is the spelling) I very seriously think that this is part of the software that is being installed. By raising the tolerances in the software less codes and lights will be triggered and to the naked eye that would give the appearance of the problem being fixed, but in actuality all that was done is resetting the norm to a different level.
I probably sound like a full tilt froot loop nut job but when looked at from 2007 to now with everything that has ahppened with software and problems it really does fall into place in a sensible yet twisted progression of events and is kind of freaky.
Gotta go, toucan sam is here for breakfast.

I'm pretty sure they not only reduced the chance of triggering naked eye warnings, but also raising the threshold of what throws a code in the system.

Consider the one plus for a high threshold - When it comes to smogging my car, I want a high threshold. Any codes trigger a failure in California.

My 2009 went in this week on the recall and I got a 446 pump. Abouth 10,000 miles ago, I took it in for a few long cranks. They went away with the software upgrade the primes with the LPFP. Injectors were not reviewed. Pump was replaced without mention of codes.

Did I read it right. A replacement HPFP is only 2 hours of service?

3. user interface for answering incoming phone calls has changed for the better

And, the bad stuffs:

1. fuel consumption seemed to be higher
2. idle speed is also higher

Are you guys seeing these as well?

My cranks went from 1-2 before the recall, to 3-4 after it.

[twinturboa51]

Just took mine in for the recall. hoping for the best. I'll update when i get the car back.

[NJANDY]

Took my car in for the recall on Thursday. Now i wont have it back till monday. The reprogramming failed.

[chromisdesigns]

Not uncommon at all. Sometimes they need a couple or three tries to get it right. Mine took two, and after that I still had to reset the BMW Assist -- so make sure you try it out after you get your car back. Very common for reprogram to cause it to need to be reinitialized, which you do by calling them.

Dropped my car off in the morning for the recall, should get it back tomorrow. Enjoying the N55 loaner I got in the meantime

I dropped mine off last week & they didn't make any promises because of some larger jobs in front but they managed to slip mine in one day (injectors only, #s 2-5, the software program update was conducted last September & the hpfp was replaced last December). I enjoyed a 335d as a loaner (still missed having a stick).

Note to self-prior to the injectors being replaced it appeared that 20mpg/tank was unattainable after the re-programing & new hpfp was installed as once 350-385 miles/tank was routine. Lucky I could squeeze 300 miles. Will monitor the situation post injector recall service but I will be happy simply to stay out of the shop for awhile after three different runs at this.

[Scrubber]

Took mine in on Thursday, got it back Saturday, computer reset took two attempts.

One thing I noticed is that the car seems more responsive in standard drive. I'll keep an eye on fuel consumption...

[gary88]

They ended up keeping my car over the weekend, SA didn't state why. Maybe because I also told them I also have an intermittent noise coming from the window at highway speeds.

Now I should actually get it back tomorrow

[NJANDY]

got mine back saturday. They replaced HPFP, LPFP sensor, 2 injectors and reprogrammed. Is it normal for the steering wheel button and 6 programmable buttons to be reset or did my tech forget to back them up?

[imajnazn23]

just took my car in for a oil change and boooommm... they need to keep my car for a day to process two recalls: HPFP and Fuel Injectors. Hope this is for the better but from the looks of it, worst mpg.

Normal -- pretty much always happen when they reprogram.

[ajsalida]

Took my 2009 e92 XI in last week, 23k miles: new HPFP (#446), 3 new injectors, reprogram. No LP sensor needed. Seems to run smoother and rev faster. Had no prior problems except one SES light. Got no letter, but had other issues and asked if they could do the HPFP at the same time. Put about 200 miles on it since, no problems.

My buttons presets were all gone too.

[gary88]

Just got my car back

Some observations:

1) Car is slightly louder
2) Exhaust burbles and pops more when you let off the gas
3) No loss in performance
4) Seems to rev a little more freely
5) My iDrive screen looks like this now:

[ajtalavera]

Took my car in on Friday for a third engine light that came on in the last several months and i finally got it back today and here is what they did:

1. Changed both vanos solenoids valves. Valves were faulty...Part# 11-36-7-585-425
2. Changed oil and oil Filter.
3. Changed all spark plugs.
4. Brake flush service.
5. Service update to HDP Programming and reset DME adaption.
6. Changed HDP pump...Part# 13-51-7-616-446

All done under warranty and did not pay a dime. So far the car runs great and the same as before. I hope this solves the issues and everyone get their problems resolved due to the HDP failure.

[DrivingPassion]

It has been almost a month since my recall was completed and cranking is still one turn of the engine. Fuel consumption seems to be stabilized and seems slightly better than before the recall.

Anyone out there getting any problems with their new HPFP after the recall?
I want to know if the recall fixed it.

[Tag]

They better resolve it or they'll have on their hands the largest class action lawsuit they've ever seen.

[MikesBMW]

i have an 07 335i and bmw keeps telling me that my car does not fall in the recall range of vins, wtf i thought all N54s were affected by the recall

[Orion4]

There are 2 related recalls (attached) one addresses the HPFP and the other the Injectors.
