Hi All.

Sorry if this is rehashing previous posts ... been seraching and have not found out if I am correct in my assumptions (and considering I work in telecomms - that could be dangerous !!)

My disco (2001) TD5's ride height is fine. If left over night or for two days the bum tends to go right down. Wouldn't worry normally but I see that the passenger side is lower than drivers. I park on a uneven surface so thought that must be the cause. So changed the direction in which I park and turns out passengers side is still further down. So that scraps that idea.

I climbed underneath and saw that the passenger bag has made dark marks on the bottom stopper ?!?

So am I right in thinking that this;
a) has nothing to do with the sensor as ride height is fine.
b) is most probably a leak somewhere in the air spring ?

Are there any other possibilities ?

From what I read earlier it only goes down that far due to leaking and drivers side is not leaking ?!?

Please let me know if I am on the right track here.

Thanks
Stuart

try spraying soapy water on it and that should show up any leaks

Had heaps of trouble for 12 months with my air springs. Never leaked when I checked with soap but if I turned my back they went down. In the finish it was the bags. The layers of rubber part with wear and leak intermittently till they finally fail. Be aware that the problem will burn out a compressor if left too long.

Good Luck

Jack up your air bags then spray soapy water all over them and you should see thousands of small bubbles all over the surface of the rubber of the offending bag.
The bags they sell at paddocks or at least the one i brought was exactly the same as the original l/r one that came off, as said above you are putting a lot of extra strain on your compressor.

When one of my ride height sesors went, the one side of my discovery went right down to the bump stop. Saying that it didn't go back up when I switched the ignition on, it just stayed there.
Replaced the sensors, done both was no point in just doing the offender & hay presto. Easy job to do too, just remember to disconnect the battery before you do it. They don't need calibrating. That's why you disconnect the battery.
