A bit of a niche question maybe, but only 3 of the buttons on the centre console light up when the lights are on. The circuit diagram shows the door release buttons illumination driven by the door ECUs, and they don't light up. Does anyone have them coming on, and when? The "lock" button never illuminates either.

Your comment helped me to find out that the door control unit is responsible that one of the buttons is not illuminated.

My passengers side lights up as follows: with ignition on the door open button lights up, with outside light on the window up and down button light up.

However, the door button of my drivers side is not illuminated at all. The problem changed when changing the door control units from drivers to passengers side and vice versa.

Unfortunately I cannot see any cooled soldered joint on the circuit board of the driver's door control unit.

Could you fix your problem?
