C350 smoke when idle

[Nathan1992]

Hi all,

I picked up a 2008 C350 petrol a couple months back. Really happy with car, very fun to drive!

The past couple of weeks I've noticed when idle at traffic lights there is quite a bit of very light smoke coming from the exhausts. When driving it stops. This happens even after the engine has warmed up.

It's my first big-ish engined car (had a 1.4 golf before this) so not sure if it's normal, or if the drop in temperature recently has anything to do with it?

No other problems, the car drives fine! So wondering if it's expected? Any advice appreciated.

That looks fine and normal, nothing to worry about.

Yep perfectly normal my 2008 C350 Petrol Estate used to do that especially on these cold mornings, used to make a lovely noise too.
