Strange Oil Leakage under the oil cooler - C200 2011 1800cc

Good day dears,
I started to notice oil leakage under the gear area of my car, this leakage started with the cold weather.
When I start the engine and wait to warm up, when the weather temperature is low, it leaks oil in a pressured way (it has some spray) , like it's pressured. See the photos here.

I went to my technician and he told me it's from the oil cooler, and he changed the gasket and still the same problem. I observed it for a week each morning and in the two cold days, it leaked this way after I warm it up.
Later through the day, it doesn't leak any oil.

Could you help with this? Do you have any idea? Is it the cooler needs to be changed? I hope no cuz it's super expensive!
Or it is a valve or something that pressure the oil in that area?

Thanks!

Hello and welcome

I‘d have a look under the car and try to find where it’s coming from.

It is best to take it back to the technician who changed the gasket. It will add to his knowledge and experience.
Tell him to check for the leak when the engine is running because that is when the oil is under pressure.

Are you using a MB specialist or any type of garage. Did he use a genuine seal, or a seal at all and just make something up.
