Not sure what age of C63's this affects but mine is in for it's first service today (2012 model) and there is a recall to change all 8 coil packs. Can't say I have noticed any rough running or startups.
Didn't know about it, but just to correct you it's not a recall, it's a service bulletin. They are two very different ways (and costs!!) of doing the same thing.
