    N54 Misfire

    Hello everyone,
    I have a 2009 E71 X6 with the N54. Seems like its misfiring . RPM dropping off while driving. Thinking of starting with changing spark plugs and coils. Don't want to have to buy injectors!! Anyone else seem this with the N54?
    Thanks guys

    Have it checked by one of our sponsors. Octane car service or M-tech Auto.

    But if you're not sure whether it's a misfire or not then it might not be your coils/sparks.

      Replaced the coils and sparks with NGK spark plugs. Misfire is gone but I'm still getting boost pressure fault :curse:
      Feel like the car is falling apart!!
