Hi, im looking for the air suspension electric schematic on a 2006 E500 4matic. Car didn't raise up, compressor doesn't kick on at all. I already check all the fuses and the relays. The suspension Relay doesn't have power and the and the same happens to the compressor. I have code 5191 "power supply valves ; Short circuit to ground". Could the problem in the control valve block dont allow power to the relay?
i appreciate any help.
Thanks

I had this problem on my 2005 S211 E500 some years ago.
The problem was the power connector to the compressor, the compressor is placed in the left side right in front of the wheel. The connector is of poor quality.
When opening up there, you should also get a new air intake hose for the compressor.
