Vibration during low RPM - BMW 3-Series (E90 E92) Forum

evssss1 · 09-12-2012, 11:58 AM

Hello Everyone.

I have just got a 2005 E90 325i sedan for a few weeks.

Very recently I started to notice that there are weird vibration (can feel from the wheel as well as the chair) when the car is at low RPM from around 1300-1600. It is pretty obvious at low speed especially when I need to keep that RPM uphill....

At first I thought it might be related to my rim and tyres as the front control arms and bushings had been replaced. Later on this has been isolated as I can reproduce the same vibration with my car in idle in N mode by pressing the gas pedal to that RPM range.

Would it be possible to be caused by aged engine mounts?

Also I started feeling it to getting more obvious after changing the oil. My garage used Motul 5w-40 for me. I knew nothing about oil at that moment until recently I come across some posts that BMW engines are quite picky on oil. Not sure if it is related as well.

Any ideas / comments welcome.

Many thanks!

Any idea? The problem is getting more obvious in this week. Anyway I will send it to garage to check up soon.
