Thread: Suspension Fault Normal Height Only

Have had similar problem suspension light coming on when all appeared normal or after raising the suspension it would not lower. Problem became progessivly worse until swiching off an restarting did not cure the problem. Have now removed the compressor and cleaned the Dryer and exhaust valve and replaced and all seems OK.
Now recall that the "farting" noise on opening the vehicle had stopped and only heard a slight hissing sound sometimes.
Could this be an indication that the dryer is blocked.

I have/had a similar problem with air suspension light coming on when all appeared normal. Turn off and restart and it would be gone. However the problem got worse and restarting had no effect. As the problem started as occasional and progressed to all the time I decided that it was probably mechanical.
Yesterday I removed the compressor and cleaned the filter/dryer and the exhaust valve. Some of the desicante in the dryer had turned to powder and was on the wrong side of the retaining pads. The stem of the mushroom shape exhaust valve was corroded. Put back together an all operated normally.
Thinking back over the problem, I now recall that the vehicale had stop "farting" and only made a slight hissing sound (sometimes) on unlocking and opening a door. Could it be that a lack of "farting" noise is an indication of a blocked dryer or stuck valve? I intend to replace the dryer as I think the problem will return.

IvanR,
Perhaps you should also renew the compressor exhaust valve when you replace the dryer as it only costs a few dollars.

This begs the question whether these items should be listed as a service item - suggested KM interval?? 96,000km???

A bit of kit for cleaning, servicing compressor.

In addition to the link, with pictures and description, one person suggested the drying beads can be renewed by microwave for 5-10 minutes. This may prolong the life a bit. DISCO3.CO.UK - View topic - Suspension Compressor / Suspension error

Hi unseenone,
is there any tricks to removing the compressor?. Does anything other than the plastic undercover need to be removed first? I tried to remove mine recently and could not get to what appeared to be a mounting bolt in behind the compressor, up near the floor. So, I just cleaned all the mud and dirt off it externaly, but of course still have a problem with it taking forever to pump up to Offroad height.
Great pics, thanks fo posting your overhaul,

I disconnect the 2 plastic pipes at the back of the dryer then remove the top cover to gain access to the bracket's top mounting bolt. The top cover is a bit of a squeeze to remove.
