Suspension air intake/filter

[101andyrob]

Hi All,
First post from a first time D3 owner, although finally getting a Land Rover has been the culmination of a life long ambition.... I have a MY08 D3 SE with 60,000 km and couldn´t be happier... But I am getting some of the pretty common air compressor issues that have been described in other posts (Slow to rise, Compressor overheating after 2 or 3 cycles from access to offroad height) and so am anticipating replacing the compressor some time in the near future.
Before I do that, I thought I would check some of the issues reported on this forum, so I am hoping to pull the compressor and take a look at the dryer after checking the lines for leaks.
My question relates to the intake/filter: Should there be a discernible air flow while the compressor is operating? Mine seems to be moving a small amount of air but not as much as I would have thought.
Thanks

Hey mate,

Not sure about the specifics of your question but it seems clear that in both the D3 and D4, it isn't designed nor will it handle a lot of height changes in a short period of time.......especially up to offroad height.

Maybe a new brand of compressor will work...there is a thread on this....but even that is a new concept, so too early to say how it will go.

Cheers,

Kev.

Why would you be doing 2 or 3 cycles from Access to Offroad - way out of specs for the compressor - no wonder it is over heating and having trouble.

Try using it as it is meant to be used and I think you will be OK for a while.

Compessor does not move much air volume but it is at very high presure. So you will not disern a lot of air going in. This is also why it takes while to get back up to pressure when it has been used.
It is designed to stop if it overheats so after a few uppy dwnies it will stop till it cools down.
As a maintainance issue you could dry the beads in the the dryer and sieve out the fines.

thank you all for your input, . CaverD3, that was the answer i was looking for. I am planning on checking the desiccant this weekend.

I had exactly the same problem, in my case I replaced the teflon exhaust plug (~$12 genuine part) and the desiccant. You'll need about 150g (http://www.silicagel.com.au/products/250-Grams-Loose-Orange-Silica-Gel-Beads-%252d-Self-Indicating-.html).

Everything has been fine since. It took about 10 mins to do the change over and about an 1hr to remove and replace compressor (the hardest part).
