P38 front suspension randomly dropping.

About 2-3 times a week I will come out in the morning (after the car has sat at least 6 hours) and the front will be all the way down but the ass end will be all the way up. The interesting thing is that sometimes when I start the car it will level out right away other times the compressor has to run for a few minutes before it levels out. There are no EAS error lights and the front bags have no leaks. Any where else I should be looking? Some days the car is completely fine.

Surprised it's not the back that has gone down with a donkey sat in it. Think you may have problems with NRVs in the valve block.

Mine was doing the same after I rebuilt the valve block with the dutch o-rings. Replaced/rebuilt with a set which wammers linked to on another post, from ebay. All happy again. £10 and an hours graft
