No it also could be that there is nothing telling the compressor to turn on,I would get a test light on the connection at the compressor first and make doubly sure that the doors are closed.One little mod i done with mine is interupt the power supply to the compressor and fit a tiny led into the cab that lights when the compressor is working.Quote:
Does this confirm that the compressor is kaput
If it kicked in on requeast and no pressure to the bag it's very likely that the pump is worn, that's why they sold so much kits like this Landrover Discovery 2 Air Suspension Compressor WABCO Pump Repair Kit Rqg100041 for sale online | eBayQuote:

You reckon you checked the fuse .. in the engine bay fuse box? This should be fine as it powers up a few other functions too(like ABS and SLABS)
If you hear the click(or you may have to feel it, if engine is running) of the relay, I would then suggest you check the connector under the (engine) fuse box from the relay .. again, just to be sure power is going to the (possibly kaput) compressor.
This connector/wire is easy to spot. Should be a single connector under the fusebox, with nice thick white and black(tracer) wire going down to the compressor.
As I remember using the nanocom you should be able to activate compressor without the engine running ie. to keep things quiet to hear the relay click.
Now, assuming that the black and white wire to the compressor is getting it's power to the compressor, one last thing to check before condemning the compressor to 'kaputness' will be down at the compressor plug. Twin wire plug, white and black as said before, and the black earth wire .. make sure the earth is connected to earth(continuity or resistance test)
Could be a weak earth path or something, so high resistance and hence not getting enough power into compressor or something.
Hi,
based on my experience the brush holder corrodes, probably caused by river crossings and condensation. If the pump is kaput but the motor goes before spending money on kitting the pump, strip the electric motor off and remove the brush holder and check for corrosion. I've had two motors with corroded brush holders that have parted company with the metal plate thingy.
I think the motors are supposed to be sealed, but that just means any water that gets in can't get out.

Never a truer word spoken, or written in this case.Quote:

The options are left or right and raise/lower. Does the raise/lower refer to the vehicle height or bag pressure?Quote:

Is there a test for the sensor?
You can watch the sensor input while you are raising that side with a jack, it should react to the movement and once both sides are equal the inputs should be close
