Hi all, Haven’t posted here for a while now. Have had the car for nearly 10 years now with virtually no issues. However, in last few months have had intermitant issues with the airmatic and the technician can’t seem to work out what is wrong. One morning I woke up to find the car had lowered and all 4 wheels where stuck in the arches. There was a warning to visit the workshop and not to drive the car as it was too low. It was towed to a Mercedes independent and connected to STAR. The warning codes were all cleared and the car resumed normal service. It was determined that there is nothing wrong with airmatic pump. A few weeks later the same problem occured again. The ESP module was replaced and the ESP fuse in the main fuse box on the driver side engine was also replaced. I was told the front and rear sensors for ride height were also checked and all codes cleared again. It was fine for about 10 days. Yesterday the car had dropped again. (I park my car on a slopping driveway) All four wheels had dropped and I could not drive it. This morning I moved it to the road where it was flat and tried all the different settings and the car raised itself to the highest level so I just left it there for the day. In the evening I decided to park the car back into the garage and now it’s stuck again at the highest level and will not lower to airmatic sport 1 ,2 or comfort. Anyone else had these issues? Any experts able to advise? I am based in Sydney Australia and used to take my car to Ollie at PCS in Horndean.
