    Thank you RangeRoller. That is certainly something I shall ask "Monsieur Renault" to look for, although I shall probably be under the lift with him. Is the average garage likely to have this sort of pipe and connectors/joint as a stock item ? I think I read of them being 8mm but not sure. Seems that half the cars out there now have pneumatic suspension in one form or another. I believe that Citroen pioneered the idea. Ah, now we know who to blame.

    I never had much luck with soapy water. When searching for leaks I run the engine until she's at ride-height and then open a door, switch off, pull the EAS delay relay from under the passenger seat (RHD cars) and then shut-up and see which corner has dropped in the morning.

    The EAS pipes are not that fragile but the brake lines might be. As RR DT has said, exhaust blows have been known to melt pinholes.

    Bags are the usual suspect, especially if over 7 years old. I wouldn't bother with Arnott 2 but their Gen 3 are the dogs danglies if you're feeling flush. Otherwise Dunlop are cheap in the UK and decent enough.

    Rarely, the air reservoir leaks. If you T in a pressure guage on that pipe (no need to cut, just add a T and guage with a bit of line before it goes in the EAS valve block) and check it in the morning the pressure shouldn't have dropped more than maybe 5 psi.

    Valve block has been known to fail, usually down to NRVs or the rubber ends on the solenoids going hard and letting by air. Talk to @kurtjohnson10 on here for spares.

    Air-dryer is also known to leak but sounds like you fixed that.

    There isn't a lot else that can go wrong other than the connectors (usually behind the A-post) or the tracks on the height sensors wearing or the compressor needing a refurbed piston os occasionally a new thermal switch.

    The main pipes are 6mm all the fittings are push fit apart from the blue pipe from compressor to valve block
    the 8mm one goes from valve block to tank
    you can tee in the inflation valves or pull the air bag pipes from the valve block and put them straight on the pipes that way you will know if the leak is pipe or bag
    if you can get the connectors and there is a friendly bike shop near get some punctured inner tubes and rob the valves out clean um up and you have a set of valves
    [​IMG]
    that may well get you mobile again put in about 60psi you can use any pump that fits but maybe not a hand pump unless you need the exercise
    most just keep a set in glove box to use as required rather than have more joints to possibly leak

    Think there are a few videos on you tube showing guys who have fitted valves.
    Are you too far away from @MarkPiercy He lives in SW France

    I strongly suspect the exhaust.
    The car always rises at the back first and if that is leaking then the fronts wont go up either

    Here's a thoughtfor you @Pression de Gonflage, behind the kick panels in the footwell there are little white connector blocks. This is a important modification for many reasons, the blocks need to be removed and the wires soldered together. They can create havoc with the stereo and the eas to name but two. My son's car would jump up and down and waste air from the réservoir and the stereo would buzz. Recently another.... Leak made the eas system have a ghost fault which never gave a problem or a code and would disappear when the white connector was blown dry with a compressor.
    Food for thought... Once those blocks are done, turn your attention to the Filtre habitacle, or the two of them. The source of the leak.... If your lucky will be from there... If your not lucky... Under the strip above the screen the sealer between the out shell and the roof will have cracked but this does give a wet headlining in most cases..... ;)...

    Just a note of caution, with a well maintained/repaired EAS system I can't see the point of adding T pieces, gauges etc just extra joints for potential leaks.IMO.;):D

    Also examine the airline ends carefully. Any small scratches can cause the o-rings not to seal properly and leak.

    To access the rear airbag airlines, simply put the car into extended mode, and then grab the soapy water. It's also easier to see wear on the airbag folds this way.
    The soapy mix needs to have a reasonable amount of washing up liquid to bubble properly.

    Thank you Gunner.

    I had checked suction at the inlet but I hadn't thought to check t'other end. I was really really hoping that I bought a new but duff compressor. Sadly, no - lots of warm air pushing out. So on to the next stage. I forget what it is but someone on here mention a litlle white thingie on the pump. I have got it off but will have to go back and find out what it should or should not do.

    Thank you Pete. I am reassured. I thought I might have overdone la Liquide de Fairy.
