My airmatic suspension started leaking down on the left side, frt and rt. I replaced the valve block and then the compressor for over heating. The ride height is constantly changing. One corner will be maxed out. And the next time the rears were all the way up. I replaced the valve block again. Normal for one day and then it maxed out the left rear and blew the airbag. The rears were only a year old. Any help would be appreciated.

[QUOTE=vesiadog;9004800]I would call around and find an Indy shop that has a MB STAR system. the Star is the absolute best way to troubleshoot the complete system and components. Where are you located ?[/QUOTE

eyes and ears are the absolute best way of troubleshooting airmatic, and it’s free.
Go look for things that look obviously wrong like ride height sensors sticking, not moving smoothly , disconnected, flipped or overtraveled in the wrong direction.
Use your ears to listen for hissing noises from bags or lines. another visual aid is leak detection spray, or you can just use soapy water and spray it on each airbag in the fully raised position. Any leak will be patently obvious as a bubble forming.
once you’ve done all of that with no result, then go find an indy with the star system. What that Indy will be able to do is:
to do individual circuit leak checks, and test the output of the pump to verify whether or not it is up to spec ( output 16 bar in 30 seconds), test valve block for proper operation, recalibrate the level in the system, measure level sensor voltages, while rocking the vehicle back-and-forth, also read the runtime of the current pump in seconds. But it cannot pinpoint the location of a leak - only tell you in which circuit you need to look with your eyes and ears.
