I knew it would be my turn at some point!
A couple of nights ago I went out with the Wife to a place with a low barrier into the car park, we usually go here I drop it into low, and in we go no problems. This time, the front dropped down but the rear didn't follow smoothly. I pulled forward a bit as the entrance is uneven, its a local nature reserve so not a made surface, to where its flatter and it did then drop down. On leaving, went under barrier, back up to normal height no issue. Then yesterday on the journey home from work I noticed the suspension was pretty harsh, especially at the back, banging over bumps and defects in the road surface.
When I parked up on the drive, I could see the car was at the low height setting, although the display still read N and no warning messages. Tried raising the height and the pump didn't run, no change in height, and the height change arrow on the display continuing to flash. I had to go out again and this time, I did get the Check 4 wheel AHC system warning, but only came on when going round a corner. What's strange, when I returned home, I left the engine running on the drive and popped in to get a torch, when I came back, the car was back at normal height and the error was gone!
This morning I've borrowed my daughters car and left it at home, but it was looking lower again on the drive. I've only had a quick look but haven't found any sign of a hydraulic leak yet. Will investigate further. I don't have Techstream (yet) just ordered a cable and discs from ebay so can't report on any codes yet.
Any ideas, could this be a height sensor issue?
