Oil leak in W205 C200 M274

[AMG33D]

For a long, there were very few problems, but now there is an oil leak.
recently reached 58k, but there is some oil leaking from the engine's bottom end.

My engine is fine, however Google first indicated that camshaft position sensor leaks are rather typical for this engine (and potentially destructive to the ECU).

Do you have any suspicions about this specific engine?

Thank you!

A sump seal?


Could you upload a picture?

Are you positive it's engine oil and not ATF or coolant?

[AMG33D]

Getting a picture is pretty difficult. It's leaving rainbow patches on wet tarmac, so it's definitely not coolant.

It appears too advanced to be ATF.


In essence, it's leaking onto the front under the tray and then spilling on the floor every now and again.

Basically, it's right behind the radiator.

The radiator typically contains an ATF hear exchanger. However, ATF is reddish-brown and smells unique.

No, it's not ATF. It doesn't resemble it at all. It originates beneath the pulley areas, behind the radiator. We'll see, I guess, because it's scheduled for October.
