Evening guys, got a weird one with the EAS, so I rebuild the entire system. New everything minus sensors and ECU and it was working fine for about a month.
It’s started today, the car is raising and lowering itself by approximately 2cm on all of the corners in all modes, less at high and acsess profiles. Does it driving and stopped now.
I’ve diagnosed it to basically the compressor runs the tank up the pressure and then while it gets to just about cut off it raises the car, compressor shuts off then the car will lower the suspension back to the selected height setting. When the compressor fires back up the same happens.
None of the airbag valves indicate as open when this happens, neither do the inlet or exhaust valve indicate that they are open. So electronically the system is sound as everything operates as it should. I’m guessing one of the new seals in the valve block has not seated correctly or got nicked on the way in.
Anyone got any ideas which one/ones it could be?
Non-return valve or a leaking inlet/exhaust valve?
Again the problem only happens when the reservoir is near full and for maybe 5 seconds before the compressor is shut off. It has to be an internal leak at the top end of the pressure.
So if I use the system a couple of times to get the stored pressure down it makes the problem go away until it’s back up to pressure.
Any help would be great, means I have a place to start when I get a chance To pull it apart again! Couldn’t have too long with fully working suspension!!
