The issue I am facing is leaving both me and my mechanic perplex:
I have new arnott bags, new mercedes block valve both replaced very recently.
the car air bags deflate randomly, it could be while driving, or while parked. Sometimes the car stays up for days, and sometimes it looses air within an hour while parked. We checked all the fittings and none are leaking.

this is driving me mad, anyone else encounter a similar issue?
thanks,

Pull codes.

No codes unfortunately

If, in fact, all fittings were checked most likely one or more pressure lines may be failing. And don’t rule out Arnott malfunction although odd both would intermittently fail simultaneously.
