ROUGH IDLE at 30k?
Hi Crew,
Our 2010 135 is now experiencing severe rough idle, we have just ticked over the 30k mark and sadly 2 months out of the time based warranty limit. Any ideas on what the prognosis might be and whether BMW will provide any warranty assistance? Also if and i mean IF , we had a JB4 fitted, should we remove this from the vehicle prior to returning to the dealer? Or will VALET mode be okay. Thanks in advance JD. |

Does it start OK? If not, might be a HPFP issues.
Does it seem down on power? Maybe a HT lead/spark plug/coil pack on their way out. Last edited by racer_x; 05-09-2013 at 03:50 AM.. |

Could be anything really, bad: spark plugs, vacuum leak(oil cap not seated, vacuum res lines popped off, valve cover gasket leaking?,ect), bad coil(s), injector(s), or carbon buildup. ???
You really need to read the code and go from there.

"If" a JB4 was fitted, remove it ASAP and take it to the dealer. 30K is not a lot and being just out of warrenty they might offer some form of good will.

I have an '09 135i with 45K miles. I changed the plugs a couple wks ago thinking it would correct my stumbling issue but it didn't. Have you gotten your problem corrected? If so, what was the problem?

edit: Having said that, when it was running "rough", the computer was actually dropping up to 3 cylinders and leaving them off so it sounded like some demented wrx on roids.
