I am currently looking at buying a 2012 C63 with the performance pack plus with 78k miles.
i viewed the car today and all was in good condition. The owner had it recently serviced at MB and sent me links to a video the tech had recorded post service, citing the overall condition of the car.
the only thing that caught my attention was that the tech said there was a very small oil leak that should be monitored, but “nothing to worry about”
I have attached some screenshots from the video. The tech is pointing to an area that seems to be just above the oil pan I believe.
Any advice or knowledge on what this could be would be greatly appreciated!
Seems like the upper bed pan is leaking. To reseal it the engine needs to come out.
i see. is that the most likely cause? it is a very small leak without anything actually spilling. could this be left and monitored as opposed to fixing immediately?

Yes if in that area, if you keep checking oil levels & monitor the leak you can leave it as most people do if it’s just weeping with no oil loss.
Check if it's indeed a bed plate leak and not a valve cover leak that's just dripping down from the cylinder head. A valve cover leak is a fairly straight forward fix. A bed plate leak is a big job, and I would be very cautious about the costs for that engine-out repair.
upper oil pan does not need engine removal. You simply support the top of the engine lower the subframe and remove the rack. Can be done in less then 6 hours.

Every single M156 with an upper bed plate leak I have seen done has had an engine out. The mid and lower can be done by dropping the front subframe.
I got sent these by another MB Tech years ago I knew.

I wouldn’t be doing the maintenance myself - however is this commonplace in garages to do it this way to reseal the upper bed plate? Don’t they usually take the engine out?

You need to read before you comment. I only stated that the upper oil pan does not need engine removal to be re sealed. I never said anything about how to re seal the bed plate. Clearly that job requires engine removal. I know because I did the job myself and didn’t have someone do it for me. Next time read before you comment.

Stop moaning you sound like an old woman and a child at the same time complaining on the internet 🙄😄 I don’t have the energy or time to waste on you.
Anyone would clearly read what you put as you saying the upper pan leak can be done without engine removal, even the OP read it the same way I did and replied to you. So maybe before moaning think about how you word replies to people.
Back to the OP/original poster check the rocker covers, oil cap & pcv first and if they are fine it will be the upper pan and engine out. As I said previously though if it’s a small leak not dripping on the ground or loosing oil leave it, keep monitoring it.
