First right front and right rear bottom out. Tried 97 different ways to reset the system. Now both sides are down. Compressor is running pulled the feed line at the top of the front shocks and both are getting air. Used a u-canic scanner cleared the codes and now it says all systems pass. Can raise the left side with the scan tool independently. The compressor runs but the right side will not raise using the scan tool. Took the tire off the right side and sprayed the boot with soap and water didn't see any leaks. When I get in the car it says vehicle raising, compressor will run for a minute or longer, but the car will not raise at any corner. Just don't want to throw parts and money in the wrong direction. 2007 E550. This is the W211 correct??
