W220 Cluster, etc problem
I have tried to google and search forums about this w220 cluster and speedometer problem but I didn't find a answer. My problem is following:
Two days ago I lost the "backlight" of my instrument cluster ( It went black but everything was working ok ), yesterday I lost the warning lights, speedometer ( everything in the instrument panel ), turning sign, cruise, dynamic seats and the steeringwheel buttons.
Today I removed the instrument panel, I have the following voltages in the instrument panel plug when the engine is running:
Pin 1 0V
Pin 2 13,16V
Pin 3 2,327V
Pin 4 2,680V
Pin 5 0V
Pin 6 14,00V
Pin 7 not in use
Pin 8 4,33V
Pin 9 0,665 - 0,779V changes between
Pin 10 0V
Pin 11 0V
Pin 12 not in use
Pin 13 0,03V
Pin 14 0V
Pin 15 14,00V
Pin 16 not in use
Pin 17 not in use
Pin 18 not in use
The transistors looks ok, but I could not find +12V anywhere from the components on the instrument panel.
Any help would be appreciated. Thank you.

Stop playing with it , put it all back together abd take it to the dealer , there is a special ten year warranty on the cluster
You have a s55k so I assume it's a 2003 or newer

Hey guys.
Well this same thing happened to my 2000 S500 a few years ago. The problem is the MOSFET's basically over load and melt of the circuit board. I tried to fix it myself but I am not an electrical engineer at all to say the least. Here is a link that explains it all. I ended up sending my cluster to the dude in Florida and had it repaired for about $750. That was of course just before MB announced the 10 year warranty on them! Hope it helps.

Please also update your profile (user control panel) to reflect the model year of your car and the fact you are (at least) in Europe.We could guess by use of the term "Kompressor" - but that's the way MB spells it in the U.S. too, so we can't be sure just from that.
You'll get better answers sooner if we know whether the car is North American, European, or Asian specification at the outset.
