In the winter, when its cold out, I've often got the shakes upon startup and then the error on dashboard... so I turn off vehicle and restart adn all is perfect... I spoke with a BMW mech about this and he said just learn to live with it as its not bad actually for the car as it warms up adn problem goes away as opposed to paying for the Lifters replacement.... he never mentioned it could be an IVM/ISM part that could be easily/cheaply replaced...interesting.

Sometimes its a rough ride, sometimes its smooth motorin'.
Sometimes she doesnt like how i treat her and sometimes i dont like how she behaves.
BUT at the end of the day, she loves it when I am inside her.
