Low compression in cyl 1 = valve job. Engine still runs a little rough on occasion AFTER the $5500 valve job. And the wrench symbol still pops up on the dash. But likely an electrical symptom. Intermittent loud foghorn noise from subwoofer that continues after car is shut off if lights are left on. Mechanic replaced evaporator valve underneath subwoofer; he dared not look into electrical stray current.  The car still doesn't go into reverse on occasion. I did not take car to Mercedes because you at dealership you speak with a concierge, not a mechanic. Ridiculous.

I noticed that the A/C was not functioning properly in that the "climate control" function could not establish and maintain the cabin at a preset temperature.

This time the dealer ran a full system check and there were no anomalies and no fault codes present.
