Got these two dials next to the passenger seat on my new (to me) motorhome, my idea is its some think to do with suspension, any idea's please and how to work it.

Thanks, Dave.

yep....remote pressure gauges for air suspension.

somewhere will be either a built in compressor or air line connectors.

just noticed the connectors are below the dials.

no idea of pressures needed but simply connect an air line or foot pump to the valves and inflate.

i would start at 3 bar (40psi) and see how it sits/drives.
the rear airbags on my 7500kg RV run at 60psi (4.5bar)

I think you are spot on as it is air suspension.

Somehow you can pump it up, perhaps with a built in pump, and you can let either side down individually with the buttons below the gauges. They may even be the valves for pumping the suspension up with

Advice given to me is do not drive with them on zero

As John says air pressure
It looks like they are both on zero which may mean they have been removed or they are not working. You should not let them totally deflate, attach an air pump to either valve and see if they go up and stay up:thumb:
I will try and get you some instructions to help

all correct, air suspension shrader valves so will take footpump or airline, now u have to pump up and drive van laoded and see how van sits and rolls on cornering, adjusting level as required by letting air out through shrader valve the same as you would on car tyres:thumb:

they look like shreader (inflation) valves to me but i could be wrong.

Inflation and deflation same as a tyre valve

Looks same set up as our airide system
Dont run with less then 20 psi you could damage airbags
We run at
Weekend away light load 30 psi
Up to well overloaded as usual 50 psi
Max I have in 70 psi and much too hard a ride
Keep playing round till you get it right for your preferences

Thanks good info to start from,
Think there's going to be a bit of trial and error here, The person who had the MH before me had it for 6yrs and never put any air in. Didn't know and wasn't bothered.
If the air bags are damaged would the normal suspension still be ok ??.
Thanks for your reply's

Put air line on and start to inflate to about 20 psi and go round back to listen for leaks if ok I would go to 30 psi and set it exactly at 30
Leave for a few days and mayby a short run if it goes down you have problem if it remains on 30 you are lucky no leaks
When you start to inflate back end of van should go up a bit
This is normal on ours from 0 to 50 psi will give about 6 inch of lift measured at towbar
When you get it right you will be suprised at hiw much differance in ride of van much more stability
