Engine shakes on Bmw Serie 3 E93, what to do ?

I have exactly the same problem..

Left the car at the local BMW service centre for a bunch of tests to diagnose the problem but they couldn’t tell me why the car shook upon start up!

Please let us know how you resolve it, thanks.

Have your knock adaptation reset. had this problem with my 330 and it helped abit. cleaning the MAF fixed it.

I reset mine with my BT Tool. if you don’t have one, you’ll probably have to have take it to a dealer.

Another problem that can causes this is a sticking vanos solenoid. I had code 2A98 being thrown in my car and I would get intermittent jerks (side to side) at start up.

If you know how, remove the solenoids and blow compressed air through them.

You car will throw a code if it detects a sticking vanos solenoid. 2A98 and 2A99 I beleive. One is for intake other is for exhaust side.
