I'm told I'll receive my C290 in March! Do I need to run the car in before hand or just drive away normally on arrival? What do most people do?
Run it in! Gentle loading of the engine, not too many revs and slowly build up.
Generally follow the guidelines in the handbook.
I'm none the wiser
Dont hammer it right at the start then do what u want. Simple.
It only affects late MY16 cars. A bad batch they think. He stated that they should be hard to remove with the tool. I can use my fingers without too much effort!!
