I am getting this code on an S430 problem is my software is unable to do any of the test to see what the problem is. Is there any way around this to see what the problem is? Both fronts go down but take over night to drop. let me know thanks....

 

I don't see it in the list at http://www.bba-reman.com/content.asp...on_fault_codes, but that list is't complete.

However, you clearly have a leak in your Airmatic system. Most likely place is the upper strut mounts; however, it can be elsewhere. Best also to replace the Siemens airmatic relay ("O" in your passenger side fuse box in the engine compartment) with a Hella relay.

You now also have search terms that will get you more than you ever wanted to know about Airmatic - but should learn anyway.
