I have a 2000 S430 and the car lowers down on all sides overnight or a few days. But it raises up when i crank up? I really need help because I don't want to buy a lot of things I don't need. thanks
If it is lowering in all wheels you have a leak in the air lines or valve block. You don't need to replace the air bags.
Inspect for leaks. Have you tried that yet?
I tried to check the lines with spraying the water method but I couldn't find any leaks? Thanks
Do you have star diagnostics scanner? Or know someone who does?
There are a number test that you can perform with that scanner.
I have replaced all struts and it still lowers in a few hours or day. I missed your reply so was my action. The airmatic light stays on. I dont have a scanner but i will try to get one. Are there any other test for line leaks or can i just replace the lines? Thanks
