2002 s430 suspension problem
Hello,
I have 2002 s430. There is suspension problem.
The car is going down overnight. Looks like airmatic suspension leak. But sometimes, it goes up to the maximum, with no reason. Like I left to vacation and it was up during a month. When I came back, I drove the car and it started going down again.
Any ideas what could be wrong?

Is there any other electronic parts that control the valve block?

If the problem is the Airmatic valve block, some folks have cleaned and refurbished the valves by replacing the O-rings.
The factory valve block (P/N 2203200258) list price is $354, is usually $275 - $300. The cheap Chinese valves are usually under $100. You get what you pay for.

It was the valve block problem. I have disconnected the hose going from air pump to valve block and I splashed the soap water on the valve side and it was bubbling from this hose connection.
I have replaced the valve block and there is no leak now.
Thanks everyone for the help!
