What about the compressor mount itself? I broke the dang stud and it's not pressed in or out it's one piece. Is it hard to replace?

Did you have any issue with vehicle being uneven on one side? My car is high on one side and low on the other

Hi I have a 2007 CLS 550 and its throwing the airmatic code: "Power Supply Valves Short Circuit to Ground" I checked for continuity on each electrical plug going into the valve block and there wasn't any. The resistance was greater than 1.5 ohms. Is there supposed to be continuity or is there only when the relay activates? Do i likely have a break in the wire? Can you please help me im really stuck!!!!

Well while I have no experience with that exact alert. Given the alert says Power Supply. Valves. Short Circuit. I would also assume it’s talking about the power supply to the valve block. Since it’s a short circuit I would be looking at using an ohm meter to touch one lead to the power wire to the valve block and the other to a good ground or the neg on the battery. If you have low or no ohms, there would likely be a problem given you took the fuse out first.

Hi, during replacement, did you disconnect battery ? Did you change relay too ?

[@MercedesTech]

I did not but it’s always a good idea to disconnect the battery and replace the relay
