Warranty is nice, but I'd like the problem fixed.

I REALLY hope that this new fuel pump solves the problem but does not introduce any new problems...

I am still shivering when I think about the HPFP fiasco in the VW/AUDI 2.0 turbo engines. Back when this engine was first introduced, there was a relatively high failure on the HPFP. The pump was driven by an extra lobe on the exhaust camshaft. It turned out that the internals of the HPFP were not strong enough and they wore out too quickly.

VAG engineers redesigned the fuel pump and put stronger internals. Great. It solved the problem with the dieing fuel pumps but introduced a bigger more-expensive problem: The actual camshaft started wearing out and resulted in a MUCH more expensive and time consuming repair job since they had to pop the engine open to replace camshafts.

In the end, VAG redesigned the engine completely where the HPFP is not driven by the camshaft. It took them 2 HPFP designs and engine block redesign to fix that.


If I have to choose between our fuel pump breaking all the time and having 120K mile warranty on it VERSUS something similar to what happened with the VAG engines, then I will gladly take our situation.

P.S.:
I know almost all of us are tired of this HPFP situation, especially considering how much we are paying for our cars, but I just wanted to give you another perspective on this. HPFP problems are not uncommon at all. Mitsubishi discontinued an entire line of GDI engines and issued recalls in Europe for fuel pump problems back in the mid 90's...

you may want to check the CURRENT(JAN 2010) bulletin pretaining to the extension of the emissions warranty for the HDP (hpfp)

it is official -- SI B 13 03 09
Fuel Systems

MY 2009 is included in the category

cheers

Thanks for the info!

Interesting that this TSB lists -881 as the new, "improved fuel pump part", instead of -943.

so true.. but it does help us understand that the problem is continuing and their willingness (albeit, late) to help out owners that decide to keep the car long term.

This reminds me of the case of the E65's in 2002 -- having the overall warranty extended to 6yr/100km. didnt prevent the issues with the car, but the owners were protected from costly repair(s) for a longer period of time ..

and obviously the NTSHA investigation wil make a determination on whether this needs to be addressed on a larger, or more proactive scale

Same situation with the early E46 M3 motors. They replaced motors and extended warranty terms. BMW has a history of making things right for original owners but patience is a virtue whern it comes to these things.

Is there even an investigation going on? Do we know how many pumps have been replaced? I mean, are we talking 50k PUMPS, or 50K cars with muliple pumps, or more?

Numbers dont lie. People losing power is just as bad as people gaining power aka Toyota and the sticky pedal.

Tommy Boy put it best, "Hey, who needs a garuantee (warranty) anyway. I can take a dump and put it in a box with a warranty on it" What we need is something that wont break AFTER our warranty is out nor leave us stranded.

Our HPFP failures is nothing compared to the mega failure of Toyota and their gas pedal...Jesus, If I was the owner of the manufacturer of the gas pedal, I would commit suicide...This is one MEGA problem, and looking at our HPFP issue, its so miniscule!

You're right...

I think that may be the case. I just heard the voicemail my SA left me regarding the HPFP with the new part #, and he said that as far as the new part # is concerned, we (the dealership) don't have a hold of that in the US yet.........And whatever HPFP I got is and should be the latest and greatest based on what they can get a hold of. This is after he checked with their part department, FWIW.

Oh well, we'll see how long this one lasts (knock on wood).

[dtp3347]

My HPFP just failed I think and I have a service appt next tuesday. Ill let you guys know what part they give me.

[GreenPlease]

I was just thinking, perhaps AMS/CP-E caught wind of a new OEM pump and decided to scrap their project. Not bashing, not flaming, just a theory...

Very confusing... thought -881 was the OLD part. WTF?!?

[JoeyBananaz18]

i guess this is good news. only time will tell

Thx, that makes a little more sense...

While I agree with you that it's definitely driver error, there must be tons of cars out there that have aftermarket - poor fitting in some cases even - mats. How come none of them had a problem with mats getting stuck under the gas pedal.

But bottom line is there must be more to the Toyota designs, if they're getting stuck so much that a recall was issued.

Here we go....again....

Bunk!!!
Sorry for the OT.....
I really doubt BMW has implemented this failsafe you are indicating above.
Correct me if I'm wrong but isn't what you are describing above, the equivalent of line locking your brake system to perform a burnout. I'm sure there have been a few here who have excersised their left and right foot to warm up their tires at a drag race event.

although the SIB indicate the use of the 881 part # -- the significant issue is the inclusion of the MY 2009 vehicles

you will note the bulletin "supercedes" the previous publication... the annoucement and the final publishing of the new bulletin occured after the improved part# was announced.. but not to worry .. the 943 is also a superceded part # and the 881's will become a NLA which will leave the 943 as the only available part.

Sounds like either they cannot prove or disprove the nature of the "actual" failure of the HDP and want track the 881 failures -- or they are waiting for additional software upgrades which may be supported by the new pump (just speculation) -- as the newest ISTA/P has additional fuel system test routines ... and a enhancement to remedy the "long crank when cold" situation.
