I agree with you entirely. BMW has to fix this issue pronto and simply providing a 10 years 120K mile warranty on the HPFP is not the final answer -- it's a Band Aid.

 

To someone like me, it makes no difference whether the warranty is 5 years or 105 years if you have to go to the dealership every 2-3 months to have it replaced, not have your car for weeks at a time AND get confronted by dealers saying stuff like "we can't give you a loaner, but we can put you in a rental" - are they out of their fucking minds? (pardon my language, but it is actually appropriate here IMO)

 

BMW HAS to fix this HPFP problem. I will never buy a 535 without a certification that this problem has been PERMANENTLY fixed and without regular tires.

All members here know about this problem and the vast majority of us will never touch a x35 because of this issue. The rest of the members who buy them, do so at their own risks and should not expect sympathy when it will invariably need repairing. It's like the people who buy houses next to an airport and then go on complaining about all the noise. The only way BMW (or any company) will listen is by voting with your wallet. Simply don't buy their 135, 335, and 535 and when they feel the effect on their wallet they will fix the problem. It's that simple.

 

I just "Downgraded" to a 530ixt due to my 535i HPFP issues...

Replacing a mechanical pump 4x a year is not a solution... most people don't even change there oil that much.

Power and Fuel econ are awesome, but does no good if you are sitting at the garage or on the side of the road waiting for a tow.

I Pray that the N55 solves the issues with the N54. I just won't be a Guenna pig for it, Sorry 5 gt owners best of luck....

 

It should not be much of an issue anymore - they are replacing the N54. The 5 series GT already has the new engine already - a single turbo 6 cylinder. From what I read the N54 was not going to meet the latest emission regulations coming into place. BMW is of course going to save some major money per car by not having to buy an extra turbo.

Additional update - the car has been in the shop for one entire work day and they are still "working" on it. (Should I tell them to just replace the fuel pump and check the fuel injectors?)

 

The dealership has now confirmed that it was the HPFP and the car is now getting reprogrammed. I am keeping my fingers crossed that the problem is solved and that I can pick up my car tonight.

What updates have their been to the programming since July 2008?

 

Does reprogramming occur after a new HPFP is installed. Sorry I don't have a clue about these mechanical issues.

I used to have my car going back to the dealer all the time a couple of years ago with the "reduced power-engine malfunction" warning. All they did was that they finally reprogrammed the car and it has been doing good until recently when BMW blamed Bad Gas for the stuttering/vibrations. As far as I know, they did not change the HPFP in my car.

 

I am not sure. I think the programming is independent from the HPFP. I am guessing to eliminate all possible sources for the "reduced power-engine malfunction" warning they are reprogramming the car.
