Suspension live data using Allcomms, seems like odd readings

My ff seems to be sitting level.
I do have a recurring fault that sends the air suspension inactive.
The fault reads too much regulation needed right rear, so I suspect I need a new airbag on the right rear.

What I cannot get my head around though are the live readings from each corner. They seem so widely different, I can't believe that they are correct. This is what I get:

Front left -29441
Front right +2
Rear left 0
Rear right +2560

can anyone make sense of these, or alternatively, anyone with an Allcomms and full working suspension care to take a look at their live data for the suspension and tell me what yours shows.

So, yes, something doesn't look quite right with your numbers .

Thanks for that. I havent seen that screen, probably cos I'm too scared to enter the calibration function, so got mine from live data. Perhaps I'll have a look at the calibration screen, as it appears you can view without making changes.

I have also email Storey, so will update with any info I get from him.

If anyone does have the Allcomms and can look at their live data I would appreciate it.

A new height sensor perhaps but not a new airbag/air-spring.

I have very similar readings on my RR looking at my All Comms live data.
when you check the live volts on the Front Left height sensor are they up in the 40s ( wh3n connected)?

if so you have the same fault as me.. so at least i can let you know what doesnt work so far!

i cant readily read live height volts on All Comms, i am using my Carsoft i930 hand held which works really well as an assistant to my All Comms..

I think Storey has given up on me, he doesnt respond to my email problems @nymore .. and i dint blame him.
