Hello, i have 2005 220cdi avantgarde and my instrument cluster backlight is getting dimmer and yellower.
The backlight adjustment knob is to the max, but only the needles, the screen in the middle and the buttons all around the interior get brigther past the middle setting of the adjusting knob.
Only the speedo, clock and the tacho are staying at the same brightness after the middle setting of the adjuster.
Lets say i turn the brightness all the way down and when i go from the lowest setting to the highest setting everything increases to the max except the clock, speedo and tacho they stop getting brighter around the middle
