Left mine for two lots of 12 hours as I had to use the vehicle.Pulled fuse 26 both times.
The following happened.Both fronts dropped,one side about 13mm,other about 6mm.Right rear stayed the same or went up about 2 mm,probably as others dropped.Left rear dropped 11mm.
Last night I left it in off road height,seemed to stay about level,probably because of larger volume of air in system,i am thinking.
Using Big Blue(a soapy solution in a squirt bottle we use for looking for leaks at work),no external leaks around valve block that was replaced recently.Maybe it is internally faulty and rear has a bag leak.I checked where air line goes into top of rear bag,no leaks.Actual bag is difficult to test for leak as it has a metal cover over it,or do you try to look for leak at bottom and top of metal cover?Rubber boot on the lower section needs to come off as well I think?
I will take it to the Indi for repair,but just trying to sort it myself for interest before it goes.
