Land Rover Discovery 3 & 4 Air suspension compressor air intake filter location.

[@charlesrowe8137]

Thank you so much and like many this has hopefully solved a problem I've had for weeks - yellow suspension light and HDC Faults and limp mode after 25 minutes driving - air compressor getting too hot and 'vehicle rising slowly'. Taken out filter which just disintegrated into a pile of dust so will seek replacement tomorrow and with fingers crossed problem solved!

[@discoveryadventures2296]

Hi, as the sponge had disintegrated it might be worth changing the compressor filter and moisture crystals.

[@stunninglawns9410]

Thank you - this has been a huge game changer for me. I have been struggling so solve my Land Rover Discovery 4 compressor issue for months and this is the 1st video I found which actually shows where to find the filter!! I doubt if the filter on my vehicle have ever been cleaned. I will send you photos of my disintegrated filter I took out should you be interested.

[@discoveryadventures2296]

Hi thank you and please it helped you. There is also a second felt pad underneath the sponge which you may wish to wash or replace. Feel welcome to send any photos Regards Peter

[@MrLjbikes]

Been looking for this for a while with an occasional (restricted air input fault),didn't realise it was so low..thanks I'll look again..subscribed 👍

[@discoveryadventures2296]

There is also a second small filter pad underneath. Regards Peter

[@notthatkindofachannel]

Hi Peter, thanks for the tip! I am sure that my filter was never replaced!

[@discoveryadventures2296]

Hi Peter. I am pleased you found the information useful. I suspect there are lots out there that have not been replaced in some time. The filter can be washed out in warm soapy water. I have heard that some have deteriorated and fall apart.

[@daniellyne1]

Same here yes thank you Peter have you got the part number so I can change mine

[@discoveryadventures2296]

@@daniellyne1 Hi Dan, you can't buy just the filter sponge unfortunately. You have to buy the pipe, canister and sponge As one. About £65. Plus vat from JLR. I do have the part number if you want it.

[@daniellyne1]

Thank you Peter ill ask my local parts FMP they have in partnership with Bearmach@@discoveryadventures2296

[@NathanNostaw]

Cheers for the tip. Closed cell foam is closed, so no good for a filter.

[@beenzer1109]

Thanks for this, checked mine this morning, all good.. Cheers

[@discoveryadventures2296]

Always good to check annually. Regards Peter

dyson hoover filter sponge is the same type of sponge and only £5 on amazon and under the sponge is another felt filter by the way that just needs to be cleand with an air line or a can of air (do not wash it) my range rover sport now lifts much quicker now that it has a new sponge

[@reinoutharkema2540]

What a good one! My filter was indeed very dirty, and has never been replaced. I called my dealer but he asked €96.40 for the filter inlc housing. Is there anyone who might have a cheaper filter? Read below in the comments, a dyson hoover filter... But isn't there an aftermarket filter for this? Please let me know :)

[@discoveryadventures2296]

Hi. I'm not aware of a specific aftermarket filter. I would just try to find a fine open cell sponge to use and cut it to shape. A pond box filter sponge might be ideal as they come in different open cell ranges.

[@stevenmayer6442]

Hi peter it’s a two part filter after the sponge you will find a white filter also.

[@discoveryadventures2296]

Thank you. I thought that I could feel something else in there. I will take another look.

[@DiscoGruffalo]

A pan wash sponge should do the job.

[@gordonwedman3179]

Tried to have a look at mine today but I have rear AC and this filter is virtually inaccessible behind the blower. I could get the cap off but not get it out of the way. Only was to get the foam out would be with a wire hook. Decided to not bother as there was not a speck of dust in that compartment.

[@discoveryadventures2296]

It's worth trying to remove. There are actually two filters one felt at the bottom and the sponge one. Sometimes the sponge starts to breakdown into a fine dust which could get sucked in and would obviously need the sponge replacing. Regards Peter

[@irishvw10]

It's a pain but you can jiggle the canister out of the mount... Lots of cuss words and a sore hand! 😂the worst

[@evick80]

Hi, can you suggest where i can buy the intake filter?mine disintegrated completely. Thank you

[@discoveryadventures2296]

Hi, this seems to be a common issue with some of the old sponges. You can buy them from Land Rover Dealerships, but it only comes as a whole unit rather than just as a replacement sponge. Lots of people have made their own by buying some sponge and cutting it to shape.

[@DrBlueTongue]

How did you manage to get the cover unclipped? I've been struggling with it and can't figure it out haha

[@discoveryadventures2296]

Hi it clips on so its just a case of a swift upwards motion and it should come off. Regards Peter

[@matthewjbellamy1]

What can happen if the filter becomes blocked ?

[@discoveryadventures2296]

The compressor could overheat or fail prematurely Regards Peter

[@matthewjbellamy1]

@@discoveryadventures2296 Thanks for the reply. Once I saw this video I checked my d3 . I didn't even know it was there

[@johnm6620]

My d4 is setting low won't go up is this the cause?

[@discoveryadventures2296]

Hi very unlikely but may have been a contributing factor. It could be one of a number of reasons why the vehicle is not lifting. Do you have a GAP iid tool or other diagnostic tool? You will need to check for codes first. Have you tried the fuse and relay? Is the pump running and car not lifting?
