What's considered a reasonable drop in suspension
I am making the way round my disco 3 started with air compressor then air resovoir . Thinking I had it sorted I locked suspension using build mode option on iid tool and my suspension drops again . What's considered a reasonable drop at the back it dropped 30 mm and the front it was 80 mm here's my readings
Put in off road and locked using iid it was on a slanted drive
Night mor eve drops total
F driver 495 450 420 45mm 30mm 75
R driver 515 500 485 15mm 15mm 30
F pass 510 460 430 50mm 30mm 80
R pass545 525 510 20mn 15mm 35
Next thing to check I think is front valve and calibration
But what about the back.
Cheers for any advise

Ordered new o rings for the front valve hopefully that will fix the big problem . I'm presuming it shouldn't drop at all after I have changed these .

yeah ideally it shouldn't drop at all.
do the front and see how it goes.
The back is a real pain to do, so best avoided if you can!

My car drops down to the stops overnight whenever it is frosty, so from the above replies I assume this means there's a fault. Any suggestions?

For mine im still working on it . I Read fault codes first then looked for leaks most likely place is the air tank under the front passenger side go into off road mode and run your hand around it or the air compressor lid then failing that it's the valves or the pipes .
I changed the tank changed air compressor lid and this weekend I'm changing valve seals on front valve
Air resouviour 100 quid
Compressor kit 50 quid
Front valve kit 15 quid

So finally I changed the o rings on the middle valve which over night made the back drop more than ever so I bought a new valve off eBay for the rear and have not had any drop overnight at the back only 10mm at the front left so more inspection needed
