Hopefully a quick and simple one - 17 plate c63s with 7G tronic. Noticed there is a whine on a cold start and when it's cold outside. Seems like gearbox as it's in sync with the revs (don't shut me down for my uneducated guess :) ). Definitely goes away when car is warmed up. I will try and take a video but in terms of the pitch it sounds the same as when pushing car quite hard and you get a similar-ish sound. Main thing for me is - something to worry about or, given it disappears when car is warmed up, not? Have warranty but don't want to rush to the dealer immediately.
