[G20330iii]

I have a 2019 330i with 50k miles when I start it and wait about 15 seconds it vibrates and it is very noticeable my wife looked at me like wtf is this the water bottle I had in the cupholder was shaking like I had 12 inch subwoofers and when I put it in reverse it’s so much worse.. I have a muffler delete and a few things coded on bimmer code like sports plus but it didn’t start doing it until about a month after I got the delete and sports plus. Is anyone else having this issue It’s a cpo with the warranty should I take it in? are they going to blame the muffler delete?

Could most likely be the engine mounts, recently I had to replace them on my 330e (I've seen a lot of people having issues with engine mounts on the B48 engines but I think mine got damaged because of the 750 nm torque) I had the same issue but it went away after replacing them.

Definitely engine mounts. Open up your hood and have your wife rev the car up to 4-5k rpm, your whole engine will move up and to the side extremely hard. If that happens its definitely engine mounts. The vibration comes from the engine touching the frames. I was quoted around 2-3k by a mechanic for labor and parts, fortunately I still have warranty and was covered under it by the dealer. Honestly shouldn't be a thing for a new car like ours. Mine is a 2021 car and the mechanic was surprised that the engine mounts were broken.

My car was shaking when I put the car in reverse, and when I changed the engine mounts, the problem went away.

I had the exact same issue with mine and it was engine mounts. They seem to have issues, especially with the B48.
