Planning a "mayor" tune-up

I have to check that part I have a mystery slow leak that has my skid plate all oil film covered but no puddles under the car. I'm sure my oil sensor is original.

It may be that. After rebuild “my” engine “we” were mad at the oil drop in the parking places. And the smell of oil no matter driving style (even at idle).
Cleaned the engine bay, the “belows”
and the “leak” showed up.

In Bentley Manual is indicated to be replace to 120.000km Oil Change.
I did at 220.000km.
BTW Schwaben scanner noted the fault up!
