Happy to admit I was wrong - 8 spheres makes it a VSX & hydractive. xantia_v6's last post is very likely on the money.martin churchill wrote: ↑15 Nov 2020, 18:40OK, I've just checked for buzzing with the door open, nothing.[I did find another 2 spheres, so that makes 8] I have a buzzing, [sounds like a fan on low speed] with the ignition on and and clicking possibly the preheat and pump cut off? #3 fuse is ok.
Is it possible to power up the EV direct? just to see if the valve is engaging . A wiring diagram would be nice if anyone has one
If electrovalve is not working for any reason (eg. wire unplugged, fuse blown/missing, or diode failed) the valve is held firmly shut by a spring. Ride stays firm. The updated electrovalves were only fitted to very late Xantias - a 1998 model would not have them.admiral51 wrote: ↑15 Nov 2020, 18:50Just an idle thought, from my distant memory if the fuse for the EV is removed does it put the car into permanent soft or hard mode ?
Need to do some digging from old posts, but think the valves themselves were updated at some stage and someone has the updated version and found the ride is much improved but no audible buzz and clicking does sound like the EV are dead or no feed to them
