Ok so I have brought my 2009 MCS in for the HP Fuel pump again. The first one lasted 1 year second lasted 1 month. This time they have kept the car for a week and it still isn't fixed as of today.

They mentioned they opened a PUMA case and that corp is telling them what to test to find out what is causing the faliures.

So far they haven't told me a thing they have done (except replace the intake - didn't work)

Has anyone else had them fix this problem? And was the fix more than just replace the fuel pump?

 

A couple guys in the local MINI club had to get a new HPFP, but their mileage was around 56K. All they replaced was the pump and that was it. Hopefully you just got a lemon and they are honestly trying to work with corporate to figure out what the hell is wrong with these damn things.

 

Be sure to let us know what the ultimate fix turns out to be.....

They did give you a loaner, right?

 

Getting loaner Friday - don't need a car during the week. I'll let you know what they fixed if I ever get the car back...

 

BMW really needs to consider not buying HPFPs from that dark alley store in Burkina Faso.

 

Yes, lots:

I'm on my 2nd replacement (3rd pump); the 2nd time they changed the VANOS, adjusted the timing, but in the end it was another HPFP that did the trick...so far so good for the past couple of months...fingers crossed.

 

If its any consolation to you out there have these problems, Mini is not the only German car company have lots of problems with high pressure fuel pumps. Porsche is on its 4th updated version for the 08-up DFI Cayennes and 3rd version on its 09-up 911/Boxster/Cayman DFI engines.

I just hope Mini is like Porsche and keeps trying to make a better part instead of acting like nothing is wrong and keeps adding the same old part hoping to fix the problem.

 

does anyone think the ethanol in our fuel could be the cause of this? the mpg drops like a rock . like a two to three mpg difference.

 

Happy to see that BMW is coming out with new direct injection engines in more of their new models...HPFP problems, here we come!

 

Ok got the car back... they said it wasnt the HPFP this time it was the Mass Air Meter. Only had the car 1 night lets see if that was it. Fingers crossed.

 

No, ethanol in the fuel doesn't mean jack. It burns like gas, fuel pumps don't know the difference.

 

So you can confirm that a high ethanol content, which can destroy other elements of the fuel system (seals, gaskets, hoses, whatever) can't possibly do anything to the internals of a HPFP? Source of this info? Color me highly skeptical.

 

+1

I'm not saying Ethanol IS the cause, but given that it can negatively affect other fuel system parts, I wouldn't be willing to definitively say it's NOT the Ethanol without significantly more research into what the actual failure is, etc.

 

Cars are designed to handle a max 10% ethanol mix. Normal gas shouldn't harm anything.

 

Rubber doesn't like ethanol, but metal is fine. Hoses, gaskets, etc. with any rubber content deteriorate prematurely when put in contact with ethanol for an extended period of time.

 

Right. Agreed.

But - ethanol is turning up in higher percentages. Read this thread over at Bimmerfest.. very interesting - and scary. Maybe, just maybe, some of these stealership claims of "bad gas!" when people show up with bad HPFPs or other problems are valid.

My Jcw will lose some power in 1st and 2nd gear over 5000 rpm when launching hard with wheelspin while dtc in on, but with everything off in 1st and 2nd pulling away from a stop with wheelspin running full throttle the car cuts out over 5000 rpm but regains power if I lift and then go back to full throttle.

Does it sound like a hpfp going bad or just the electronic hand of god/bmw stepping in when traction is lost?

 

Why must you refer to Dealerships as Stealerships ?

Did a Dealer make a profit on a transaction with you?All private and public traded companys should make a profit.

Did a Dealer rob you?Break into your home?steal your candy when you were a child?

I am 2nd generation Dealer and offended by the term Stealership ! Dealerships are one if not the biggest employers in the USA.

 

BMW/MINI doesnt make the parts, they only install parts made by their contractors, who may/may not have stringent quality control protocols. LuK Drivetrain Systems (clutches, flywheels) is a good example.

See my comment about dark alleys in 4th world countries.

 

Generally, I don't. None of the ones I've done business with anytime over the last decade or so deserve that title, and I don't refer to them as such. But don't try to kid us and imply that they're all on the up-and-up. In this specific case, I'm referring to dealerships who have told customers that they are denying a warranty repair due to "bad gas", without producing any evidence of same. It's happened over and over again, there are many tales of it here in these forums. No explanation of their definition of bad gas (i.e. ethanol content too high? Contaminated? What??!), no explanation of their (alleged) testing procedure, no nada. THAT is horrible customer service.

Sorry if I offended you. If you're one of the good, honest, conscientious dealers, then I have the utmost respect for you and all the other well-run dealerships across the land.

 

Sometimes the factory will not pay and outright reject a warranty claim that will leave the dealer eating the cost of the part and the labour ,once a dealer has had a few claims for the same repairs denied by the factory the dealer will not offer that repair under warranty coverage.

You think the dealers are tricky just try and deal with the factory.
