And they have the audacity to call it "Software Engineering"..
The day I picked up my GL45, I noticed a warning light telling me the "Intelligent Lights System Inoperative", which persisted after a software upgrade.
Resolved by fitting a brand new headlight unit.....
We have had the same issue, they have had to order a new bracket which the camera sits on, problem is it is not made my Mercedes so we have been waiting four weeks for it to arrive. In the meantime the dealer advised we turn off the collision prevention assist manually each time we start the car. Hopefully this is fixes it as the car has been in and out numerous times with a combination of answers from software update/overspraying the bolts which earth the car to the bracket mentioned above.
