Hard Vibration on cold start when idling
Posted on BimmerFest as well.
Hi all - new owner here of a 2012 x35i with 104k miles. Really enjoying the car but have one lingering issue. After cold start and normal cold start procedures, once the idle drops the car vibrates like hell (coming from engine area). As soon as you touch the gas or start driving its completely smooth. When coming to stop line a second after stopping the vibration is back...so much so that the vibration shakes the rear tailgate pieces and makes a lot of noise. This usually will last for the first 10-15 minutes of driving until the car is completely warmed up. Oil is Liqui-Moly 5w40 with probably 4k miles on it. Have no codes and even scanned it to see if there was something but no codes and all diagnostics look ok. My first guess is the engine mounts or VANOS solenoids not working exactly right, but wanted to get some opinions before I try to troubleshoot in the next few days. As mentioned as soon as slight throttle is applied its extremely smooth again. Any input is much appreciated. |
