    Almost 80K miles.... When was the last time the fuel filter was changed? They do a great job catching particles protecting the injector but depending on the quality of the gas the filter may need to be replaced....

    Probably never... Should I replace that before taking it to the dealer u think? I know it's going to be at least an all day ordeal if I go there...

    Can someone verify this is the correct OEM part number for the fuel filter:

    2007 n14 turbo

    11 25 2 754 870

    According to the RealOEM illustrated Parts List http://www.realoem.com/bmw/enUS/select that's the number for "Repair kit, fuel filter". There's also an "Activated Charcoal Filter" for a lot more $$. You need to decide which, if not both to replace --- sorry, I can't help --- mine are still OEM at slightly over 80K miles.

    Dealer had no problem replacing my HPFP under warranty, and they knew I had head work plus the Garrett and 3" exhaust. Supposedly, if the mods have no effect on the failed part, warranty should cover it.

    The Gnatster is not a normal MINI..... It's had it's share of issues but seems to be OK now... Nathan can perhaps better answer this question...

    This is what I just ordered... I always get nervous ordering parts I think it's what I need to replace though. I don't know what this charcoal thing your talking about is

    The activated charcoal filter is part of the EPA fuel system ventilation system used to capture hydrocarbons from being released into the atmosphere. Typically the filter that gets clogged with particles from impure gasolene is 11252754870.

    There is a thread somewhere in the forum that shows the steps to replace it yourself. You get to it under the rear seat from inside the cabin. You need to relieve the fuel pressure and have plenty of rags around the opening... It can be messy and if you spill the gasolene when you take the plastic threaded cover off, you will remember your error for the rest of your ownership.... Especially during hot summer days... And those mirror fresheners won't get rid of the gasolene stink....

    Oh.... And don't be tempted to suck up the gasolene residue around the filter with a shop vac...:D

    OBW, did you show any hpfp codes prior to replacing? All I'm showing is low injector pressures. No misfire, lean codes, super knock, or any type of cel for me. The only way I saw the injector codes was with a pricey reader.

    How was the hpfp diagnosed?

    Maybe it's just the filter..

    Hopefully they'll replace the hpfp anyway..

    Why? Are they going to try and replace the filter first? Or tell me to come back after I do?

    I refuse to spend any money at the dealer. Period.

    More often than not, overfilling kills the EPA canister, aka, the charcoal canister....trying to squeeze in that last 95¢ of fuel to fill it up all the way....STOP on the first click... don't go 5 or 6 more to "top it off".
    It's good till its not.
    It's not a your issue.

    I would suggest you check the psi on the in tank pump....it provides "head pressure" to the pump....sometimes the low pressure in tank pump is called a "lift pump" in some applications. Not sure what the specs are on it...but I would suspect if the HPFP is having to struggle to "suck" up enough fuel it could be causing issues....in aviation, and even in some diesel applications, the lift pump, transfer pump, etc is there to ensure the supply to the HPFP and prevent cavation, aka vacuum bubbles that can form around impellers/gear pumps, etc....the bubble cause accelerated wear, and pump failure, and lowers flow....that's kinda why I kinda suspect it might be an issue in more cars than MINI realizes...it seems the same people have repeated failures with HPFP's... gasoline quality, maybe, running them dry/low, maybe, bad luck. Maybe....my gut says there is more at play.

    Is it bad to pull the fuse and run the pump dry before pulling the fuel filter to relieve pressure or should I just shield my face and have at it?

    I would imagine Mini would verify lift pump pressure before giving me a new hpfp? I would have no idea how to check that, does it show up on live readings from a scanner? All I saw was overall pressure and individual cylinder pressures on the auto logic...

    That MINI dealership was so hipstered out I almost pooped a little. I felt so strange without black framed glasses and skinny jeans in there. Idk if it's their uniform or what but I found it pretty comical..

    Ok so here's what happened, I'll try to explain the best I can the story:

    I was sitting on a curb, zoning out in the parking lot of the dealer when the service advisor called and told me it needed plugs and coils...

    I said ok just throw the parts I had back in there and I'll source them myself...

    In the meantime I slunk into the garage area where my car was and started talking to the dude working on my car who happened to be a master tech there.

    I explained my situation to him letting him know coils had been replaced already, and was actually one of the first things my tuner suggested. This is also the third set of plugs with the latest set being heat range 8. OEM NGK plugs are heat range 7 and my tuner told me since I already replaced plugs and coils that I may need colder range plugs.


    The tech offered to let me drive the car on the dealership parts to verify the problem was fixed and low and behold it was... I was shocked. He explained that hpfp problems will usually always throw codes, run terribly upon startup, and will improve as the car heats up... He said since my problem was consistent hot or cold that's what lead him to spark diagnoses...

    So I told him to throw the stuff I came in with back in there and went and paid for the diagnosis ($150).

    I then proceeded to roll over to the parts counter and purchased coils that I could be certain were legitimate, and installed them myself in the parking lot. I let out of the lot with a howl and instantly encountered the same problems as before. Hilarious.

    So I shot home an re installed 4 of the 8 heat range 7 OEM plugs I had lying around and problem was solved. Again. For fun I installed the last set of heat range 7 "OEM" plugs that are the blue "IR" NGK models, and they ran like sht again... So the proper plugs were the green NGK "R" plugs, not the blue "IR" that people claim are OEM. Very confusing, I hate NGK with their ever changing part numbers and endless cross reference charts it's ridiculous.

    So to be clear:

    Blue NGK heat range 7 "IR" ILZKBR7A8G---WRONG
    Blue NGK heat range 8 LKAR8AI-9-----WRONG


    There were never any CELs and the tech said the low injector pressure codes was low rail pressure, probably from the computer pulling timing not recognizing the resistance in the different coils.. With the new dealership coils the car did not like the heat range 8 plugs for some reason and I hear that's what everyone is running that's modded out... Maybe it's because I'm currently at high altitude I'll talk to the tuner and see what he says...

    So to put it simply, it needed OEM plugs and coils lmao. Pretty embarrassing... I guess that's what I get for trying to save money where I can sourcing parts idk..


    Rock auto claimed the Delphi coils I purchased were OEM and they did in fact look identical with one minor difference after further inspection compared to the coils the dealer had. The insulation at the bottom was ribbed instead of smooth. (See pic) so they were in fact different from OEM, even though it was from the same manufacturer looking very similar...

    The correct coil is the one with the smooth insulator

    No codes that showed up on my AP, just very difficult to cold-start in the AM --- lotsa cranking before it caught, then lotsa pedal-pumping to keep it running, and all this only after a couple high rev runs that seemed to stress the HPFP before shutting it down the day before. Once it started and smoothed out, it performed as expected for a 282HP (then) sleeper. No high-stress runs before shut-down - no hard start problems.

    After a couple days at the dealer, I finally "stressed" the HPFP and left it overnite again to initiate the hard start symptom. If the dealer found a code, they didn't tell me. Since I was an out-of-state customer, they provided a loaner. Made it almost like a vacation.

    So hopefully I can get my hpfp to crap out before next year it seems to be ok for now... Just don't trust it yet, I'm waiting on another F up

    I'm still gonna change my fuel filter when it shows up, I'll pos a pic of its blackish blackness
