View Full Version : Suspension Compressor inlet filter

The Discovery Service schedule has this line at the bottom:
Air suspension vehicles used extensively in arduous/ off road conditions will require the compressor inlet filter to be replaced at more regular intervals
But, unless I'm going mad, the schedule listed above this statement does't list any 'compressor inlet filter replacing' at any point...
Is there a separate instruction somewhere, and if not, what are people doing? (ie, what is the recommended 'less regular interval' implicit from this statement?)   Mine's an AMK, if relevant...

The inlet filter is tucked up behind the rear left tail light cluster. It is held in place by a tab on the panel. You can reach it by hand after removing the inside rear panel cover. Just follow the hose up by hand until you feel the canister at the end. Just lift it off the tab and bend it all back down towards you. Unless you regularly drive in very dusty conditions and/or have dusty stuff (like hay, I suppose) in the back of your car, I wouldn't worry about it. It should last the life of the compressor.

Excellent.  Thanks mate - that clarifies it nicely...

Learn something everyday. I've serviced the compressor and valve blocks, never thought to check the inlet point.

I took out the foam in the filter and went to wash it and it may as well have been fairy floss as it instantly dissolved. 
I just cut out a bit of a foam car wash pad to the shape and put it back in there. I don’t see this as ever being a source of great trouble in most urban cars. It’s inside the cab effectively although there are breather flaps behind the tail lights where dust can get through in the most terrible conditions.

I bought a cheap generic air compressor filter canister off eBay and filters to suit and replaced the factory unit. Cost about $20 and have five spare filters.

Yup - I did use the search function before posting, but found nothing.  Subsequently I found another thread that implied that, whilst Diesel's answer is spot on, it's a bit of a bastard to do... But of course I now can't find the thread for you all!
Hey ho, I reckon its a nice to do unless I charge across the Simpson doing burn-outs...

Mine is in a very similar condition to yours. It will totally disintegrate if I submerge it. 
Did you ever have any problems replacing it with some car sponge?
Thanks

That’s all it is now a bit of sponge cut out to diameter Asprey filter but there is a proper filter pad at the bottom you can properly wash. Same as the flat white ones in the compressor
