Oil cooler GLC 250D

Hello. I kept reading, on Romanian forums, that at 100,000 km it is recommended to replace the oil cooler (for the 250D model). Have you replaced this part?

Hello,

why is it recommended?
Who recommends it?
Transmission- or Motor- Oil Cooler?

Motor oil cooler

through unofficial channels. It seems strange to change something that has no problems. The explanation would be that there are deposits on the cooling channels of the cooler and the oil is no longer cooled.

One more question. In Romania (or at least I do), original Mercedes engine oil with the rate of 229.52 is put in the engine (2.2 euro 6-250d). Do you put something else? or other oil quality.
