Disco 2 air suspension (again i know)

no, its a cheapo foot pump gauge is probably well off on it, and i dont have a decent gauge,
i did pump it up to 3 psi on the jack then took jack away it just sunk on the floor, so im guessing that the gauge on the pump is crap

Did you work out what PSI was needed to got to the height required?

If you want to know what's the pressure in the bags with vehicle on normal level i can tell you that for an unloaded D2 the pressure in the bags is around 70psi , the more loaded it is the higher the pressure but AFAIK the mechanical pressure limiting valve is set to 90-100psi to protect the bags from blowing

Actually, I was more interested in knowing what he found , as he asked the same question when he asked about the kit. Are you saying that pressure increases if the force increase.................what a shocker....

Cheers

i was up to bar 5, with that kit
anyway nanocom arrived today, stuck it on and had a look, easy to use i might add
some one must have had a nanocom on this prior to me buying it,it was in transport mode for one,
air was switched off and changed to coils ,other than that once i change it ll back the compressor runs and pumped the system up to 120 left and right not a clue if these are the correct values but looks like it is sitting correct
also noticed an air flow problem with the engine, to low? will have to look into this now, put the valves in the glove box because you never know
but i did notice that the drivers side bag had went down a bit over night
so think i may change the bags in the next week or so

will have a play with the defender in the morning

As @sierrafery said, "i can tell you that for an unloaded D2 the pressure in the bags is around 70psi ". A pressure of 5 bar works out as 72.5 psi.
To check that everything works correctly, measure the distance between the centre of the wheel and the edge of the wheel arch. As @neilly advocates, it should be 473 mm +/- 15 mm.
You can use your Nanocom to make fine adjustments.
Don't leave it too long before you change the bags, if they're leaking the continual re-inflating can put excessive stress on the compressor and its motor which could start getting a tad expensive. It's good practice to always change your bags as a pair.

bags ordered will do them next weekend ,on the nanocom, what is the height value to input?

It doesn't work quite like that. They need to be set at the correct height and then use the unit to set the calibration. Land rover dealers have blocks that sit under the rear bump stops, which they place and then set the calibration. You could make your own or set it at the distance from the centre of the wheel to the wheel arch.

the amount of discos 2 on the road with air, and the trouble you get you would have thought some one with a nanocom would have read the values somewhere down the line and wrote it down

Those values can be different from one vehicle to another and affected by different brands of sensors, they are simply irrelevant as numbers, the real physical height is important as the body to be horizontal all around and if that's OK you might see different numbers in the inputs but just save target heights as to keep the even level and neglect those figures if you see what i mean

sierrrafery helped me out when my sensors were goosed, the value i reset with my hawkeye, sent it back to get up graded for free, 2 days later back home, 2 new sensors on tape measure and hawkeye, job was done easily, plus 1 of the sensors was faulty would not calibrate at all,
