X5M hesitates when starting?!
I have a X5M from 2010, 18' miles. When starting the car it hesitates for 2-3 sec and then starts. Sometimes it starts as soon as I push the start button but most of the time it takes 2-3 sec for it to start.
What could this be? Any known issues on the X5M? When up and running the cars goes with any problems. Just the start issue. Thanks! |

My educated guess from reading on this forum is injector issue.
Do a search for injectors or black soot and you should find quite a few threads describing long cranking at cold start. |

Finally brought it in and dealer said 3 injectors were faulty. CarMax warranty was going to cover the 3 injectors, but BMW replaced all 8 and plugs under goodwill. 2010 X5M w/ 52k miles. |

This may sound off tangent, but I had a similar issue with my Diesel X5 a few weeks back. Anyway, the issue went away after I charged my battery. I understand that we are talking apples and oranges here, but check to make sure that your battery is charged up.
I used a Noco G7200, and it was amazing! |

If I had to start somewhere, I would start by changing out the plugs and coils as well as cleaning the Mass Air Flow Sensor. If still an issue, then I would run back to back fill ups with techtron followed up by cleaning the throttle body out with some intake cleaner and a small, wire brush. I would then be doing a sea foam via the brake vacuum line smoke show. If still doing hesitation after start up? I dont know.... Maybe change out the MAF?
