Hi to all.
last week i brought my sl 55 to my mechanic to change the abc oil. They changed the oil 13 liters and the filter. All is good don't have any abc warning lights

my problem is that my car drops below the normal level after like 15 minutes of standing.

please let me know what it could be as this is starting to bother me and my mechanice does not know whats going on.

Possibly not bled properly.

Doubtless your mechanic either introduced particulates into the ABC, or the oil change process dislodged particulates which are now caught in the valve blocks. Two 15-minute Rodeo routines run back-to-back might cure the problem; otherwise, you'd probably have to remove one or both valve blocks, disassemble, and clean.
