Air Suspension Questions

Gday guys....I have been searching through the forum for air suspension related posts as I have a bit of an issue...its not working. The other posts have been a great help, but none of them answered the specific questions that I need. Hope some one can help...here goes:

1. Is the air pump that is under the nearside door supposed to make a rattling loud noise when it is operating.(had this for almost two years and it has done it all this time...but making a louder noise now and the bags dont fill) or is it almost silent operation?

2. I am a long distance from a reasonable mechanic, is it something that is easily changed?

3.Is it going to do damage with me driving it around with its arse dragging around with no lift? (is it sitting on the bump stops? cant tell from the cursory glance I gave it this afternoon ..42c...couldn't lay under it for too long..too hot...going out early in the morning while its still in the low 30s.)

ETA:...sorry...forgot to mention its a 2001 D2 V8

mine has never made any noise m8

Driving with the back sagging ain't going to do it any good, and will play havoc with your headlight aim!

A Newish plated TD5 passed me in the fast lane of M6 on friday night Dragging his Ar*e, the back end must have been on the bump stops, so in guessing either it was carrying one hell of a weight or the air bags had failed.

Probably the latter, keeping the back level whatever the load is the point of air suspension.
Not all TD5's had it though.

The SLS compressor should be quiet in operation,yours has been dying for a while.To change it needs a flatblade screwdriver,a 10mm o/e spanner and a 10mm socket and rachet.The only problems are ocassionally the bolts corrode into the brass inserts on the platic housing and need cutting off with a grinder,and secondly - much worse the SLABS Ecu will get fed up and go into fault mode logging " Compressor duty cycle exceeded" type faults.Sometimes these have to be cleared before it will work again.Here in the UK I see quite a few that die because the intake filter gets waterlogged and then the comp seizes up - unlikely in sunny WA !
