Air suspension D3

Hi all fiddling with my latest project 07 D3 had some suspension issues first compressor filters replaced this now created enough pressure to show up the leak in the tank so replaced that went around all fittings with fairly liquid leak on valve block so fixed that now no leaks but now front suspension goes down overnight a little more on the left it seems removed wheel arch liner today no leaks must be airbag? drops 2 1/2" overnight rises straight away no gongs or lights have ordered strut today

Sounds like bags. mine has just slowly started to drop fronts over night.

Yes thanks the conclusion I had came to left go"s down more than the right so will replace that at the same time I do the bottom arm bushes later this week picture show drop from off road in 18hrs
