SITREP continued.
Once pump was back on I tried to see if it would work. Once again it failed to come on so I used the Nanocom to force it on. Once again the rear of the car went right up but the front failed to move. When I checked the valve status the rear valves were closed and the front were open. Sound right?
Here's a picture of what the Nanocom thought was going on and it seems to reflect reality. Note the rear way past target height and the front way under.
Might be hard to see but the rear target is 105 and actual is in the 130s / 140s. The front target is around 120/130 and the actuals are 70/80ish.
I fiddled around for some time and then suddenly the rear dropped and the front rose and it ended up st standard ride height. It is almost as though there's a valve between front and rear and it isn't behaving itself.
I did manage to get her to extended ride height but only by forcing the pump on using the Nanocom.
After a bit more messing around the pump started coming on on its own again although there still seems to be some front / rear instability, although eventually it settled down to standard ride height. I've left her like that for now and will check in the morning to see if any corner looks low.
As a final check I checked for fault codes again. This came back several times with "Invalid Fault Code" (nice) but after a few attemps at clearing and rereading it just went back to no faults. All very strange.
By the way, I tried opening and closing valves using the Nanocom but nothing much seemed to happen. Is that normal? Nanocom deflates system OK though.
So, something odd still going on. Could the EAS outstation (under the driver's seat) be acting up?
