Hey guys,
I’ve had both front struts and the compressor replaced on my 2003 E500 and the car won’t lift. I don’t hear the compressor turn on and am now getting code 5303 - (y36/6 airmatic central reservoir charge valve: ground cable short circuit to GND). Can anyone help with finding this issue? I’ve searched online and am seeing that the valve may be blocked or that a crimped or cut wire may be the problem, is there a way to trouble shoot this and drill it down?

TIA - Any advise would be appreciated - the car has been at the garage for a month already and I’m at my wits end..
