GLC300de from jan 2021, just under 20.000 km. several fault indications, active lane assist stops working after a few km, dead corner assist stops working after a few km, computer indicates defective blinkers and lights but all lights are working. Car is since two weeks in the garage waiting for a new regulating unit? They have already changed the start button, did not change the problems. Anybody experience with similar faults?
Thanks, Wimvon
