Oil leak
Hello
i recently found this oil leak in my 2014 C220d ,
one screw was loose so Im not sure if the oil is coming from the oil pan seal or from that screw itself, I attached a photo if you can determine source of leak.
another thing, any procedure for oil pan reseal for this model ? Thanks​

I think you solved your own problem. Just tighten, clean and see if there are any leaks. Also the pan uses a gasket and not a sealer.

Thank you for reply, so a loose pan bolt can leak oil ? Because after tightening it i only found few dots of oil.

The pan bolts have a pattern so the pan must be sitting flat and often some people over torque the bolts bending the pan. Yes, when you drive the oil moves back and forth and yes, the oil can drip pass the bolt.
