after about a week and a few hundred miles and a fair few upsies and downsies with the suspension(not quite as good as those dudes you see on the telly in south l.a.) and....................

............the araldite is still holding Very Happy was easy-ish to get that cap off the compressor,gave it a good clean inside with hot,soapy water,bit of a sand with fine grit paper,another clean with hot,soapy water,a good dry with herselfs hairdryer set to very hot,applied the araldite while the cap was still hot so it would flow into the crack,left it for a couple of hours,put it back together and so far so good Thumbs Up

Suspension height problem.

What a superb forum, I didn't bother testing the air receiver for leaks just replaced the top cover as suggested and the fault was fixed, thanks for the advice.

Yep all fixed. If you get this DTC it appears to be the issue for most people as looking at the cap from outside you can see a manufacturing line in the plastic that i would suggest had caused a weak spot.

When i got my car serviced they wanted $1800 (for AMK replacement i said nah its ok). New dryer cap was $83 delivered from eBay, 1 hour of my time and 1 skinned knuckle. Well worth it.

Thanks everyone!

Genius, good job Thumbs Up

I know there are a lot of posts for this problem but I started new topic for the way I solved it.

Here's the way I repaired couple compressors.

If you have "Suspension fault" "Normal height only", yellow suspension light on the instrument cluster and air suspension control switch inoperative, LED's off on the button arrows.

The fault code is

C1A20 64
C1A20-64
C1A2064

Here's what service manual says

Compressor fault
Reservoir pipe air leak
Reservoir air leak
Gallery pipe air leak
Intake filter blocked/restricted
Intake pipe blocked/restricted
Air suspension intake silencer blocked/restricted
Corner valve stuck open
Pressure sensor fault

But the actual problem is the compressor dryer cover crack leak. There're two holes in it for 5mm exhaust pipe and 6mm line to reservoir-gallery. The gap between holes has a micro crack which leaks the air.

To find out the the crack exist you need soap water spray the area there and turn one the engine to start the air compressor automatically pump the air. At first it might look like leaking pipe connectors but the problem is crack.

I have manufaturred couple of these dryer covers in stainless steel and couple in aluminum. Used fast release connectors for pipes.

No need of new compressor, no need of new dryers which is no longer available from Land Rover
RQQ500013, RQQ500014, RQQ500015, RQQ500016, RQQ500020, VUB504700.

Couple of these I've done without removing compressor from the car just removed bottom plastic compressor cover.

PM me if you need one of these or email me

How to Do It Yourself DIY

Tools required

-ratchet
-extension
-10mm socket
-T30 socket
-utility knife
-14mm open end wrech
-swivel extension


First of all locate the compressor box under rear left side door, it's a black plastic box. Remove lower compressor box cover, unscrew 3x 10mm bolts and unlcip plastic fasteners.

Cover removed

Locate blue and orange connections, crack should be there, use sprayer with soapy water to detect leak and find a crack. Start the engine to run the compressor, if compressor doesn't start lower and raise the vehicle and compressor will run.

When crack detected turn off the engine, disconnect battery negative, disconnect two electrical connections by the compressor to have more room. Disconnect pipes from blue and orange holes by pushing blue, orange rings and pulling the pipes out.

Use T30 to unscrew six caps screws, I recommend to start from the top. Remove the cover, hold it tight, there's a spring behind the cap.

Replace red o-ring, put the spring back in place, put new cap in. Use small amount of soap or other lubricant on red o-ring for easier installation.

New cap in place

Put quick release joints in finger tight. Use 14mm open end wrench to tight but don't use too much force. Push 5mm pipe to side connection which was in orange before. Use utility knife to shorten 6mm pipe 3cm which was in blue connection before and push in center connection. The quick release joints require to push pipes to the very end and the pull back.

Connect electric connections, battery negative, run compressor and use soapy water to make sure there's no leak. Put lower cover back in place and you're done Thumbs Up
