luis62 Thanks for the hard work and info. It's driven ok from Cambridge to Kendal. So maybe I'll just do without for the time being !

tony50 I done some research about your airbag 2of my old Motot factors I tried could not get them , but one said usually even if the air bag is ok it's usually found on disassembling that the bottom and top plates usually need replacing as they get very rusty and most people modify and fit a whole different airbag kit to both sides.
I also phoned Pirreli Tyres head office as I could not find their airbag dept. they said they franchised this out but don't know if the folowing company still do their airbags co. name Consberg ,tel no .01283 492000 , I tried them on your behalf but only got answer phones , maybe cloesed for Easter , ps if you have got a steel wire showing I suspect you should not use it

airbag suspension

Thanks Tony,
I asked a mechanic to investigate where the air was leaking from. He didn't do that but removed the bellows, thinking he could install a new one, but then found he couldn't get one. I've looked at the bellows and think you're right: although the wire rope around the middle of the bellows has a broken strand (it's a double bellows with Torpress 23B written on it), there's no sign of damage inside the bellows, but there's lots of rust around the top so it was probably leaking around the top plate. All I need now is to find a mechanic who will clean up the top plate, apply some gasket sealant, and reassemble everything. Anyone know a good mechanic in the Cambridge /Royston area who can work underneath a motorhome?

Is it the Bellows that are leaking , or where the Bellows sit ,often there is a leak either between the top plate its connected too or leaks around the pston where the airbag moves up and down on ? if so when air bag is removed ,(fairly easy job ,Switch off engine apply Handbrake ,chock wheels that are not being removed , remove one end of shock absorber fault side (both sides if jacking up both sides of vehicle) jack up Chassis high placing / adjusting support / safety stands as you jack up chassis .
Drain out air if need be , sometimes airbag gets stuck to mounting plate or piston , after removeing bag if leak was at top check top plate for rust holes and get it welded up , we used to have leaks on 17 and 24 tonne trucks and found if airbag was not holed we removed airbag checked top mounting and piston for hole . if no holes cleaned up rust from bag and from piston and plate ( now this you may think is a bodge ,probaly is ! but it works apply flexible gasket cement to top plate and piston if they are a bit rough ,reassemble.

Please, please don't attempt this repair if you are not competant , p.s. If it's actually the air bag go round motor factors ,or , breakers yard but check for cracks if seconhand .

if you don't understand above PM me

Autocruise Colt air suspension

As far as I know this is not an original Iveco system. From what I've learnt, it is an addon installed by Autocruise when they built the Colt. There are two pressure gauges just behind the driver's seat each with a Schraeder valve for pumping up the pressure. Autocruise bought the Kuhn air suspension system from a firm called LVS in Daventry. The bellows itself has Torpress 23B written on it which seems to be something made by Pirelli. LVS say it's no longer made - but they mean that Kuhn no longer supply this system. The bellows on one side of the motorhome has a pressure leak, so I'm driving around with one side working and the other not. I'm hoping to get a smoother ride if the broken side can be repaired. Getting level on a sloping pitch would be brilliant too !

selstrom The Iveco system only lets you adjust the height if static or traveling at less than 20 kph. Above this speed the system sets the height.

It is useful for leveling on site and raising the rear when using steep ramps when boarding ferries.

Also have what would seam to be a level sensor connected to the rear diff, or at least it should be,, at present this has either come off, or been taken off,,,

Is this sensor to maintain a certain level on the rear ??

Was the a factory fit system?
If so Iveco use a system by a company called 'Wabco' (on the Daily's anyway, so i suspect all would be the same)

The 'level sensor' you speak of is a Load Sensing valve. With a standard leaf spring setup the sensing valve adjusts the braking force to the rear when laden.

When fitted with Air suspension the valve should be controlled by a penumatic acuator (as the vehicle's height would be level even when laden, thus reducing braking force to the rear even though you need it)

The actuator corrects this as it adjusts the load sensing valve based on the system pressure, not height.

I actually did a job yesterday on a Daily with problems with Wabco system (always setting its self to the highest setting)
A little 'De-Engineering' later and we had a manual controlled system and one happy customer!

The third button is the reset button-after raising or lowering, this button is used to reset suspension to the pre-set default setting. Alternatively the suspension should reset itself when driven away attaining a speed of 15 kph
