The engine jerking

Atom Ant · 04-25-2021, 10:32 PM

Hello guys, starting up the cold engine of 2017 340i and we start to moving, when i put the second gear at low engine RPM (but above 1000), the car starts jerking, i need to push in the clutch, because jerks are strong. After a minute the problem goes away.
Do i need to take to a service or how to solve this problem more easy way?

Need to let the car warm up.

Have to start somehow to warm up engine

. Wow, your engine has insane amount of torque, i would be curious. My is stock. Can the transmission handle so much power?

It's probably going through the cold start procedure. Need to let it finish (that's why it goes away after a minute).

You don't have to drive to warm up the engine, but you do need to let it go through it's startup transition phases, or this happens.
