MINI High Pressure Fuel Pump (HPFF)

MINI Cooper S R56 High Pressure Fuel Pump (HPFF)

If you have been reading our blogs and Facebook page, you know well the issue w the BMW High Pressure Fuel Pump (HPFF) associated w the 135/335/535 N54 turbo motors. This was not a small issue, this issue of the failure of the HPFF affected 10’s of thousands of BMW owners, from 2007 thru 2010. BMW went thru four iterations of this fuel pump before they found the right long term solution.

Now we have the same issue rearing its head with the newer MINI Cooper S turbo motors (MINI Cooper S cars from 2007 thru 2009, 2010 and newer seem to be OK and may have the newer designed HPFF). These motors also have two fuel pumps (one in the main fuel tank, and a second high pressure fuel pump on the side of the motor). The main fuel pump in the fuel tank runs at the normal type of fuel pressure (output of about 5 bar), but the secondary pump, the HPFF, runs at 50bar at idle, and runs at 120bar at wide open throttle. The newer MINI Cooper S turbo motor is also a direct injected motor, which is why it requires the HPFF unit on the side of the motor.

So, what is the issue? The HPFF dies. But, it doesn’t just die all at once. It prolongs the issue, confusing the owner. Some have been reported to die all at once, with some having the pump die while driving the car on the freeway, and this is a scary event. But most have a series of events that gives some hints that the HPFF is starting to have issues (although most owners don’t know that these symptoms are signs of the HPFF dying). The car will start having some surging when driving. Then it will have difficulty starting when cold. Finally, it will run, but feel like a diesel truck, and when you get to this stage, the “check engine light” (CEL) will also come on for “massive misfires”.

Is this a KNOWN issue? You bet. So much so that MINI has issued another letter to customers talking about this issue and saying they will take care of it WHEN IT HAPPENS. But not until it happens….oh my.

Here is the text of the letter from MINI USA

MINI USA has become aware of a potential problem that could affect durability of the high-pressure fuel pumps in select 2007, 2008, and 2009 model year MINI vehicles equipped with the N14 turbocharged engines.

While we estimate that only a small percentage of vehicles will develop a problem, MINI USA will demonstrate the confidence we have in our product by extending the warranty for the high-pressure fuel pump to 10 years or 120,000 miles from the original in-service date, whichever comes first.

All terms and conditions of the Federal Emissions Defect Warranty, the Federal Emissions Performance Warranty, and the California Emissions Warranty apply to the extended warranty. Warranty coverage for all other parts is not affected. Warranty terms and conditions can be found in your Service and Warranty Information booklet.

    The dealer refuse to verify my issue although I have video of it and used autlogic to confirm low fuel pressure.

    I have the exact same issue with Mini Marin. Classic symptoms upon cold start. Used autologic to read HPFP flow rate under WOT. Its 25% below where it should be. Dealer refuses to acknowledge the problem.
    I wrote service at dealers for years and really cannot understand why they are in denial.

    Hi there – my 07 MCS has a leaking HPFF – I want to make sure I am buying the correct part number pump (not one that has been sitting on the bench since 2007!!) – does anyone have the correct part number? My local BMW dealer won’t give it to me.

    I just dropped my car at the dealership and was told the pump needs to be replaced. Unfortunely since I am out of warranty I would have to pay out of pocket. Is there any way you can foward me the letter.

    I had a 2009 S with this issue. I had the unit replaced 3 times over as many years. So unless they were using old pumps to replace the faulty batch, it’s still an issue. In fact, my wife’s 2010 S is in the shop today for this same reason requiring $1400 to repair since it’s out of warranty. We brought up the letter but since it’s a 2010, we’re out of luck.

    i just to my mini to the dealer to have the high pressure fuel pump replace under the warranty. now they are telling me they cant test the pump cuz they cant get the engine running so they want to charge me $1200.00 for carbon cleaning and $166.00 for testing.now this is the kicker they are saying that if get this done then they will check the HPFP… wen i already explain to them that the pump was tested before the engine stop running.note:they say is under warranty bud they want to charge the consumer for some other stuff to pay for the pump.

    My 2011 had a failing HPFP. It was replaced under warranty, as I was still under factory warranty. There is recent talk of the HPFP on some 2011 S models being replaced under some kind of warranty extension recently announced. I would press MINI harder. It’s obvious that the N18 can indeed also have failing HPFP’s. Mine is production date 2/11.

    HPFP went out in my 2010 MC Clubman S in February of 2016. Even though the vehicle was built in September of 2009 MC is telling us that our vehicle is not covered by the extended warranty. Paid over $1300 to have the HPFP replaced. I am now hearing from other owners of MC vehicles who are saying that additional year models have been added to the list of MC covered under the extended warranty. I have now communicated with 2 others who own 2011 MC who said their HPFP had to be replaced and they were not charged for the replacement. Does anyone know if that is true?

    Just had issues with my 2010 Cooper S. Hard start when cooled off, frequent hesitation under hard acceleration. I was well aware of the HPFP ISSUES and extended warranty on 07-09 models and talked to MINI USA and they told me no dice. Took my car to a trusted local mechanic to get the brake rotors, pads, and sensors replaced, as well as the HPFP. They were having trouble diagnosing the fuel pump issues. Took the car to local dealership, and they confirmed the pump failure, but said it wasn’t covered. Total to repair, 2037$. After a friendly interaction with my service advisor, they were able to work out a total cost to repair of 863$. BMW IS COVERING THE REST. Having a well documented service record helped, and working with a quality dealership did too. Car was completed in one day, I pick it up tomorrow.

    My 2010 Cooper S clubman has been having issues since new. HPFP replaced under warranty at 26k miles in 2013. Now at 56 miles and has the starting issues, always has had hesitation/misfire under full throttle for a second. Dlr. in Denver is saying not covered by the warranty extension. Just had the decarbonization done last week by independent. Dont have build date available right now, but maybe June of 2010, was delivered in August. Any updates on BMW owning up to issues after 2009? Have not talked to them yet.

    I have a Mini Cooper s 2011 and I’m having problems with the HPFP. How do I proceed to get it replaced by mini under warranty?

    All MINI’s are now covered by an extended warranty.
    Your dealer will have all the info. They will need to diagnose and validate that the issue is indeed w the HPFP, but once validated, it should be covered under your extended warranty.

    On February 19, 2018 post, Admin stated that All Minis are now covered by extended warranty. Mini is saying the extended warranty only applies to 2007-2011. Am I missing something??
