I've had the engine management light appear for the last year or so, the car (2013 220 C class) doesn't seem affected and runs normally. Had Merc change the gearbox oil recently, and was told by the not to worry about it....if all this is true, why have it there in the first place, and how do you turn it off (other than having Merc charge me, to do just that)?
Thanks in advance for any thoughts on this!
