I have a BMW E91 325i with the N52 engine. While driving , I shifted to 2nd gear, and suddenly the car started vibrating at every speed and in every gear. You can feel it more intensely in 1st gear; it also vibrates when the car is in neutral with the clutch engaged. It vibrates the most at around 1100 RPM; if you increase the RPM, it doesn't feel as odd. I've already replaced the spark plugs and coils. What could it be? When you turn off the car and then restart it, the vibration seems to disappear until you hit that 1100 RPM mark again. If you maintain that RPM, the car continues to vibrate at lower RPMs. Does anyone have an idea of what it could be? No error codes, by the way.

Wow... that's unexpected. Thank you for posting the resolution to your issue.

I had a strong vibration when idling and driving. When the car was on the lift, we saw a lot of grease coming out of the gaps between the engine and transmission, so if you ever have a vibration, check if a lot of grease is coming from there.
