I know that I have harped on about this before but I am convinced that the air bags are not the prob when my suspension keeps dropping. I think that it is a valve that is defective rather than the bag itself. I was sitting in a car park yesterday with the engine switched off and the back of the vehicle kept dropping in intervals with a sudden jerk.:nospamhere:

Can anyone advise me accordingly?

Thanks Aviator,

If I convert to springs will there be a big fuss with my insurance company as my LR is a 7 seater?

If it was the valve/hight sensor, you would hear the valve open and the air escaping/vehicle dropping and then a clunk (valve shutting) when at correct height. Mine drops when we get out most of the time but only 1-2cm.

If its i constant hissing until the vehicle drops right down then i would go for air bag/valve block/pipe.

When my car was dropping, i was convinced it was a height corrector. It turned out to be a leaking air bag which was replaced and everything was fine.


Hope this helps.

As it's supposed to.

The Disco 2 (as the man just told you) is designed to drop the chassis-height about 20mm shortly after the car is stopped and the engine turned off.

I have no idea WHY they arranged this, but that is what happens.

Start to worry if that does NOT happen.

I always assumed that it drops when you get out due to the reduction in weight causing it to rise slightly, so it then drops to the correct level.

i think it drops to help the rear passengers get in and out of the stupidly designed half opening rear doors.

It might be that, but I suspect that the idea was that if they always let the car down a bit when it was stopped, then the suspension system would always pump the car UP to the running height as soon as you start up. It might suit the system better always to start off a tad LOW, rather than risk starting HIGH if the airbags got heated up on a hot day for example.

You might be suprised how much a Disco 2 might rise if it was parked at normal ride height on COLD airbags, which then heated up to daytime summer warmth.
