Dogbash

Hi everyone, recently noticed my car producing smoke/steam from under the bonnet. It is coming from the back right hand side of the engine bay. I think it is leaking oil and it is dripping onto the exhaust as it smells like burning oil.

Car is a 60 plate C63 with 32,000 miles. I know the earlier cars had engine problems but thought this was sorted in the newer ones?

Any ideas what could be causing this/anyone had similar?

Thanks,
Andrew
