Does anyone have experience with engine oil leak on this model ? 2015 C300 W 205. checked all the usual suspects but can't tell where it is coming from. Am suspecting crankshaft seal but not sure.
Got low oil indicator so added a quart, a week later received low coolant indication, added some to reservoir. Oil cooler and hoses are dry. found oil on the front passenger side, going down and back towards the oil pan. starter is greasy ( I think it is starter at the base of the engine)
Any suggestions? Thanks !

 

What happened when you added the quarter. Is the car eating oil heavily. It is normal if the consuption is like a quarter every 5000 kms. Oil leak is serious and has to be treated immediately. I recommend you stop guessing and get your dealer to fix it. You might end up with other issues.
