2011 bmw 335i shaking when accelerating

kaito · 12-27-2023, 11:16 PM

As stated above, Anytime i'm taking a turn and accelerate too much through it the entire front end rattles. This also happens when i set off from a stationary position and gas too fast, whether i'm using the paddle shifters or purely automatic the entire front end shakes. only seems to happen between the "1st" and "2nd" gear change. My best guess is a trans on the way out but any information helps.

Have you checked for codes? I would start from there. Also how about your engine/trans mounts?

I had to change engine mounts on my relative's car before.

The symptoms were the car wouldn't shake only when it was on neutral.

It would shake a lot when it's idle or going at very low speed on either Drive or Reverse gear.

Does your car vibrate under braking?

no just acceleration while it "shifts" from "1st" to "2nd" gear

It only happens when accelerating heavily while my car "shifts" from "1st" to "2nd" gear

I had thought about the mounts but then wouldn't it shake throughout all gear and acceleration? rather than just between shifts on "1st" and "2nd" gear?

Right, have you googled it? Try that.
