Good day all,
This concerns a Disco2/ES of 2000? When I was on holiday two weeks ago, I suddenly got the SLS alarm with erratic chiming. The air bladders held pressure though. Since then, I replaced both bladders and I fitted a new piston ring on the air compressor. I found Fuse Link 9 under the bonnet blown. I checked the valve block. When I apply 12V on either valve, it opens and both are air tight. No leaks. I replaced the Fuse Link and now the compressor is running however for 30 seconds only, then it stops. I renewed the ride height sensors two years ago. When the compressor is running, no air is getting into the bladders. I haven't measured the voltage on the air valve block connectors yet, it appears that they don't open. My question is this....does anyone know if only one ride height sensor is broken, does the ECU automatically prevent both air valves from opening in order to avoid asymmetric expansion of the suspension? Finally, when I jacked the vehicle up at the rear practically dropping the wheels, (simulating high ride position) the air valves were opening and I could hear air escape. I am not sure though if both valves opened. Would appreciate advise on the matter before I rip the lot out and put springs in instead.
