Hi, this may be a stupid couple of questions
But I generally don’t no so thought this is best place to ask
Does the m2 comp have a differential if so does it need serving and when?
And also cam belt does it have one or chain n when does it need changing

Sorry if this sounds pathetic but I thought I’d ask

Differential - yes, if same as my OG it requires an oil change, not sure on the interval

S55 engine is chain driven, no scheduled maintenance I believe

The diff is 50K miles or 6 years, and known to weep/leak as well. Just keep an eye on your garage floor and don't bother with it unless you see drips, then it's time to get it fixed.
