Garage Cabinets, Garage Storage, and Garage Organization

Hi guys,

Can anyone help me to resolve my problems on my C230?

The engine idles very high (in between 1800 and 1200 rpm).

Once the engine is warming up there is a smell of burning inside the car!

Looking at the water it is brown in colour and the oil is dark brown (not in the water but engine)

Has anyone experienced this or similar problems and can you give me some assistance please.
It would be appreciated

Thank you very much.

It sounds like you may have a cracked block or blown head gasket. I would recommend having your cooling system pressure tested at a respectable garage.
hope this help.
