F30 violent shake during start up and shut down

[adrtta]

Is it normal for the f30 318i to have a violent shake during start up or shut down? It happens just at start up or shut down. Not when idling. Anyone can help?

Should be due to the reason it’s a 3 cylinder engine. But not sure if once prolonged, it will get worse anot.

Drive back to PML asap

Might be ignition coil problem
