High Pressure Fuel Pump Problems on R56 MINI Cooper S Models

If you are the owner of a 2007-2009 Mini Cooper S model you need to be aware of the problems Mini & BMW are having with their High Pressure Fuel Pumps (HPFP). This was a well known issue on the BMW N54 turbo engine and it affected thousands of BMW vehicles between 2007-2010, so much so that BMW issued a recall. Well the Mini customers are not getting the same love from BMW, and there is no such recall to replace these under warranty. Mini did however extend the warranty to 10 years or 120,000 miles, whichever comes first on the 2007-2009 S models only. So if you have a 2010 or newer vehicle or a vehicle over 120,000 miles you are not covered. It is important that you take your Mini to a specialty shop only, because if they are reputable and know these cars they would refer you to the dealer for warranty repairs. A lot of shops, especially general automotive repair shops are unaware of the extended warranty and might try and sell you one instead.

So, how do you know if you are having the issue? Well that is a good question and it is not always easy one to answer. The HPFP does not always just die, it sometimes prolongs the issue making it confusing to diagnose unless the check engine light comes on. Some of the pumps have been reported to die all at once, with some even failing while driving at freeway speeds, causing the engine to die (very dangerous). The most common symptom that the HPFP is starting to fail is engine surging while driving. This is usually followed up by difficulty starting, and then when the engine finally does start, it runs poorly (feels like a diesel engine). When you get to this stage, usually the check engine light will come on and register misfire codes, thankfully making it easier to figure out.

Our recommendation is that if you are having any of these symptoms to get your vehicle to a certified Mini Cooper specialist and get your vehicle checked before it becomes dangerous, and so that possible warranty coverage may be verified.
