Thanks, just to add car raises and lowers and has not dropped overnight. IMO no leaks, I have changed valves previous.
First port of call I am going to disconnect the exhaust from the back of the compressor to see if that affects it in any way.
I will also put inline compression fittings around the reservoir to aid future replacement, the LR idea of the screwed voss fittings is rubbish imo.
ur so welcome , indeed i also got fed up with those Voss connectors along with the cost
hope u don’t mind me adding but if u have diagnostics that provides live data u can plug it in before removing the dryer end pipes before and after to see if the pressure changes , at least it will tell u if the boot air intake filter is restricted
best way to double check for leaks is by measuring the heights and then pulling fuse F26 from the engine bay then leave overnight then recheck heights
seeing that after it’s locked and goes into sleep mode it will wake and do a self level check every 6 x hours , so by disabling the self levelling u can see if there’s any leaks as the valve blocks then won’t open, but can flag any of them letting by, so In the morning u can see if maybe just one corner has dropped , just a really effective test
other instances where this test works very well is if the reservoir valve block is letting by and air tank is leaking
indeed any compression fitting that uses an olive / compression ring should have an insert in order for the olive to bite and prevent crushing of the pipe like the voss connectors do, where as it’s not required on pushfits
if u have diagnostics what are u using plse, if not can recommend a few for u as in all honesty with these vehicles having one is a must
hope that makes sense and other links are useful to u
plse let us know how u get on
