Just bought a 2021 E 400d premium plus coupe with MBUX. The ambient lighting above the instruments and sat nav isn’t working but active immediately below. I’ve been through the settings and it doesn’t seem possible to isolate this item. All function well on my 2019 coupe and a friend who has just taken delivery of a CLS his works as well. I’ve taken a peek on You Tube and similar aged models seem to has this lifting working too. Anyone have any ideas?
