2015 328d US spec n47 diesel
98k miles

Owned since 2019 and 40k plus miles with no previous history of this until recently.

After cold start (I live in CA and never gets below 40 F) engine shakes quite violently until warmed up. This does not happen consistently. Sometimes it starts normally.

Idle RPM is normal at about 600. Video doesn't capture how rapidly it is shaking. No lights on dash and ODB scan shows no codes.

Is it the cover or the whole motor? If whole motor I would inspect the motor mounts

It's the entire engine shaking. If it were the engine mounts, wouldn't it shake at idle even after the engine is warmed up? By the way, I just tried a cold start and it didn’t shake abnormally so it’s not consistent.
