TD5 Air suspension! Help! Wont lift disco!


Recommended Posts

Hello, just changed an airbag on drivers side on my 51plate disco. The air bag filled up nicley and went into shape perfectly.

Turned engine of and put the wheel back on and restarted engine to finish filling the suspension but it wont lift the disco off the stops! Not sure if compressor is firing up now! would it of cut out if overheated? The compressor is only 5months old.

Any help would be brilliant as cant drive it with the ow bar almost on the deck!!!!!!!!!

Thanks.

Pete.

You haven't damaged a height sensor when lifting it have you? (perhaps overextended it, or turned the operating lever inside out)

Just changing a bag should not need recalibration but if you have damaged a sensor it won't work. IIRC the compressor does have an overheat cutout (the D3 one certainly does) but if left for a while should sort itself out and looking at the UK weather forecast lately, it shouldn't take long to cool off :)

when the ride height sensor snapped on my D2, after fitting the new one the air bag wouldnt reinflate.

Landie mechanic mate of mine suggesting i turned the engine on and off about 5 times in quick succession (engine idle for less than 10 seconds each time) and then the compressor kicked in and up it went.

no idea why it needed switching on and off so much, but it worked. He reckons it happens alot and doing the above usually sorts it.

Thanks for the tips, will try them out!

How do you mean turned arm inside out bog monster?

Pain in the bum this, thought id do it myself and save £200 but dont wana mess with it again. Thougt it was too easy, changed bag in under an hour (havent done one before) Anyway, ill keep trying any idea. Thanks alot guys.

P.s. the ride height sensors were ok and not damaged as i did check them both when i cudnt get it to work!!!!

Thanks again for all your help!

When I changed an airbag and suspension was not inclined to rise I drove back and forward over a piece of 3x2 wood or similar a few times and then it came up .

I came up with this plan because the old airbag used to go down intermittently and starting the engine had no effect - and I found that moving the Disco so that the rear wheels moved up and down worked every time . Hope it helps . ;)

Ive tried the turning the disco on and off 5times to no avail, all it did was throw up the off road height light, so does that mean anything? it was on constantly!

Will get a piece of wod out tomorrow and drive over it a few times, see what happens!

Am i completely useless or does everyone have trouble with this like i have!?!

Thanks again.

I don't......

....but mine has real springs ;)

Yeah, ive have been thinking about doing that, But i have a few issues:

1 My disco is a 7seater?

2 I tow a 10x5 ifor and a horsebox occationally with 2 horses in!

3 Unsure of how involved changing it all is as you have to alter ecu setting etc!

Any thoughts?

I have a vague recollection of a P38 coming into my local specialist place with a distinct lean on it. The owner had changed an air bag and one side wouldn't inflate. They jacked the body up at that side and it sorted itself, something about the sensor going out of range when it had been sat on the bump stops ?

By jacking the body up a few inches the sensor sorted itself out and away it went - poor bloke had driven 40 miles at 20 MPH to get it to the garage and all they did was jack the body up which he could have done at home :)

i changed mine over to springs when air bag went,cost £80 for parts ,easy to fit ,i turned air suspension light off with my rovacom.

Was it a straight forward job changing from Air to normal springs. I have a problem with the drivers side intermitantly deflating as well, but it goes back up when the vehicle is moved

It depends on your abilities, but it's a straight bolt-on job. The kit comes with everything you need. It's wise to clean the threaded holes out before trying to fit the bolts - they fill with grit.

Changing to springs on a 7 seat Disco 2 is very easy but not a good idea. 5 seater Disco's were 'Type Approved' for air and spring suspension but 7 seater's were not so even if you get your insurance company's approval it is technically an MOT fail as it is not within type approval for the vehicle.

Why don't you get air valves, two T connectors and some 4mm air pipe and blow them up manually. Also useful if the compressor develops a fault. I inflated mine manually for over a year.
