I would still suggest checking the pipes running round the chassis first. I always go for the simple and cheap things before moving onto the more expensive ones Smile

"Normal ride height only messages" tend to point towards the compressor being on the way out.

Ok. Here we go. Set it at off road height this evening and then pulled the no 26 fuse. If it doesn't drop overnight I will declare no leaks and change front valve unit. If it does... well, at least I know it's time to mix the water and soap.
I parked it at 17:15, and now at 23:50 it hasn't dropped. Annoying I have to do a bit more work before bedtime. I feel like a kid before christmas and just want to go to bed to be abled to check if there migh be a gift in store for me tomorrow morning. Laughing

An update. The test in off road height was inconclusive. I didn't measure the height and couldnt tell the next morning if there had been a drop.
Tried again at normal height with no. 26 fuse in, and it dropped to access height.
So tonight I've set it at off road height and pulled no 26. In 6 hours it has dropped 1 cm. Will check in the morning.

4 cm lower front this morning. Rear had no drop. I have the valve unit and will replace and check air system for leaks at the same time.
