Airmatic suspension problems
Hey I have a 2002 s430 and my air suspension is not working my scanner is telling me I have a fault code for all four level valves I can delete the code but it comes right back I was thinking the problem was my valve block but when I took it out and manually tested it it seems to be working I also checked the connectivity of the wires going to the module and they are all good too I bought the car with this problem so I don’t know how it happened I’m guessing my module might be bad just wondering if I’m missing anything before I order in a new module and valve block to see if it fixes the problem as it seems kind of weird all 4 valves would fail at once
