Hello,

Just couple hours ago I was relplacing parking light bulbs and headlight bulbs and when I was done, I took the car to better place to check brightness. When I started the car, instantly Check VSC light, motor light and DSC ( light came on. I took whole airfilter housing off, windsheild wiper hose off. Did I touch to something I was not supposed to? Also when the car was not running, I took parking brake off to reverse couple meters.

This was the first time these warning came. Any ideas what may have caused this error? I have OBD reader but I'm afraid to clear errors if there really something wrong with the car.

Let me know what should I do.

Thanks in advance guys,

I don't have a 220d so not sure if you have a MAF... But since you took your airfilter housing (intake im assuming) off. You may want to check the maf sensor/connector.

Yes there's a MAF sensor. It might have been not plugged when I turned on the electric (didn't start the car, just double clicked Power button) to check if headlights are working. Guess that may have caused this error?
