Can anyone help me diagnose a problem with my self levelling suspension on my s211? The rear drivers side had dropped this evening and when i started and drove the car a short distance i could hear the compressor working away periodically. Then when i stopped the car to check ride height i could hear air escaping by the wheel and it was down but not fully. I took a chance and drove the car a couple of miles further to leave it at my in-laws for the night rather than the extra 5 miles home. When i checked the wheel again there was no air hissing and the wheel had stayed at the right ride height. I’ll check it again tomorrow when i go over but meanwhile i’m Trying to figure out what the problem could be. Any help would be greatly appreciated.
