I have a 2014 C200 W203 with only 95000km on. It started leaking a small amount of oil. Took it to a mechanic and he said it's the transmission oil pump that makes the oil circulate when the vehicle shuts off during eco mode. I am in South-Africa so the guy quotes me R8000 or $450 USD for the replacement of the part. Is this a common problem? What is that part called? Is this a reasonable price?

 

You're in the wrong forum. Your car is a W204, not a W203.
