Throttle issues from a standstill
Hi everyone,
I've encountered this issue a few times since I've had the car. From a red light, I'll essentially give it full throttle without hitting the throttle button with the pedal (the best way I can describe it is I give it about 80-90% throttle, but I won't click the throttle button). The issue is this. When I do that, obviously I reach around 4-5k rpm before the car automatically tries to shift to second. Just before it tries to shift to second, the car will sort of "bog" or jerk a bit, at which point I let off the throttle and just drive normally. This doesn't really happen when I have it in S mode or when I shift manually (but to be honest, I just don't really recall whether it does or not in those modes), and I can't remember exactly if it happens only once and then the car is fine afterwards for some time. Also, I thought it may be my traction control, but I turned it off this morning just to test it and lo and behold, it did it again. The car has 32,500km and is a 2013. All maintenance has been done and I do an oil change every 7-9k. Anyone encounter something similar or have any suggestions? For a bit of clarification, I can go WOT without any issues from any other gear. Going from 1st to second while giving >80% throttle from a standstill is when I SOMETIMES experience the issue. |

Yes, I got mine changed and 4 out of 8 were no good. If you drop a plug, from 3feet down, it's will be gone for sure. I suspect that happened to mine, dropped during shipping or something like that. It's develops micro crack in a ceramic part of it, and if you push your car, if will miss fire. Will give you exact symptoms you described.

Hello,
I have a 2013 X6M. The same type of bog or choking occurs between 1st and second when I accelerate full throttle in M mode. I was told by BMW Dinan techs that it is the engine cutting out before shifting, as the rate of rpm increase is so fast in 1st gear. If I manually shift at ~4.5K rpm, it does not choke. Regarding plugs, I agree, but maybe you have old problematic injectors. Even though I have a 2013, I had the older -08 injectors installed. I did have rough idle and loss of power problems, and BMW changed them (and all plugs) under warrantee to the newer improved version -11. Check that out. Cheers, |

Just for my own reference, would you happen to have the part number of the new injectors? If not, no worries. Thanks for your help |

Your BMW guys know there was a problem with -09 and below, many engines had them replaced at dealer cost. Here are some links: http://www.e90post.com/forums/showthread.php?t=651538 http://www.xbimmers.com/forums/showt...php?p=16533432 Cheers |
