Hi guys. Got my x5 a few weeks ago. I have never owned a bmw or a turbo engine before. I have a question regarding with this n55 engine as it seems to rattle and vibrate on the steering wheel when I'm at a red light. I have owned other cars, they rattle and vibrate more when the AC is on as heavier workload is on the engine. Is this a normal thing for a n55?
I normally just put 91'gas that contains 10% ethanol. Just yesterday, I tried to put in 94 gas that contains no ethanol, the vibrate and rattle seems to be a lot lighter and acceraration is more responsive. Could this be a gas issue? Or the vibration a normal thing for this engine/car. Thanks for the help!! Last edited by lawjai; 11-15-2017 at 05:33 PM.. |

How many miles is on the car?
Regardless, I have 2013 XDrive 535 and very, very minor vibration is present at idle but it is most likely due to XDrive configuration. If you are 60k or more, have spark plugs replaced and Injectors cleaned. It is a must, especially the injectors due to Direct Injection configuration. If vibration is still present, seek to be investigated by a mechanic. Quote:

The Service Bulletin at the dealer does call for Injectors to be flushed/cleaned at 60k miles interval. I am not sure if additives to the fuel tank will be enough to clean all the carbon buildup in Direct Injection engines.
As far as your vibration, is it minor that can be felt at the steering wheel and maybe at the hand-rest or is more pronounced throughout the entire car? If minor, it is normal due to XDrive configuration. If it still bothers you, I would go to a dealer or BMW Indy Shop and get e second opinion.
