hope somebody can help please ,, I'm after buying a 2011 cooper s convertible and its putting on the engine management light , the code it put up was p0087 , there are no real symptom's really , car starts first bang and goes well most of the time with no affects , sometimes it throws up a message on the dash saying car has decreased power and go to mini service (high emissions etc.) it drives like there is no turbo then , if you turn the car off and then on again it sometimes clears the dash error and it drives 100% , what I have done , I took it to a local mechanic who plugged it in and it says low pressure at the fuel rail , and there is a misfire at cylinder 1 , he said it could be a few things , clogged fuel filter (turns out its a lifetime gauze in the tank) damaged fuel line faulty injector . I drove the car for another week and the car started to miss , took it back to the mechanic and it turned out that no1 coil pack was faulty (he swapped it to another cylinder and the fault moved to that cylinder) so we though this was maybe the fault , well its put the light on again , I pulled the unit out of the fuel tank and dismantled the gauze on the in tank pump and its not clogged or there is no kinks or blockages on the fuel line under the car .
what now ? I have googled and read as much as I can find and keep seeing high pressure fuel pump being mentioned but the symptom's are not like mine at all , my car never fails to start ,
help please , thanks ken

 

If it’s getting a low fuel rail pressure, sounds like he high pressure fuel pump. Not an uncommon fault. Contact your local dealer and it might be replaced under extended warranty.

 

It's not covered under warrenty in the uk :-) if I was 100% sure it was the hpfp I will buy one , but if I did buy it and it turns out to not fix it ???? I'm going to book it into the local BMW/mini dealer to see if they can confirm what it is ,

 

local bmw dealer confirmed it was the HPFP so


just to put closure to this topic ,, mini is fixed !!! it was the HPFP , local mechanic fitted a new one today and the car is flying ,,, he did notice that somebody had been messing with it before as one of the bolts was loose and a clip was broken , so my symptom's were completely different from any others I read about online (and I have read a lot of topics) mine was always easy started and never died out !!!! one other thing I only discovered , I had read about when you press the sports button the car would spit and back fire :-) , well mine does now but didn't before , she must have been getting starved of fuel even when the EML wasn't on , thanks anyway and hope this info helps others ! ( paid £490 on ebay for the pump, cheapest I could get)
