128i Idle vibrations

Obei · 12-06-2020, 05:03 PM

Hey everyone so I have a 128i with 168K KMs and I've been running to this weird issue where the car's floor on the passenger and driver side would like shake, it's like a weird rumbling feeling that happens at idle and on drive, the second I put it in N it goes away. Mind you the vibrations become worse when the car warms up and reaches 550 RPM, the second I go to 600+ RPMs the issues disappears

Any help is appreciated thank you

Could be a multitude of things. Vanos, coils, motor mounts come to mind but I'm no expert. Hopefully someone else will chime in with ideas. In any case, you'll likely need a good BMW indy garage. We know of many; where are you?

Like the guy above says, strong possibility of motor mounts eroded down.
My mechanic says that he saw the same issue on my car. Need to get that fixed.

I also think it's probably motor mounts. Check your car for codes, specifically misfires. If you don't have any codes, that points towards mounts.
