Thanks very much will get round to checking that either later tonight or tomorrow

Right so here goes. Doing some more checks this morning (voltage/earths etc) could only find 1 issue. For some unknown reason the voltage signal from the suspension ecu to the compressor relay is getting lost. After a struggle i managed to check the voltage from the suspension ecu and i have...

Also if i manually trigger the compressor relay the compressor runs. It seems as though its just lost the switch signal from the ecu to the relay

Cant get the codes as we can not access the suspension ecu. Can access all others but not suspension.

Unfortunately there is nothing there that helps. Could really do with full wiring diagrams so that i can trace wires etc. Have now found out that the ecu is not sending a signal to the compressor relay. Have voltage coming from the ecu when the car is running but its getting lost on the way to...

Hi again all. i am looking for some help tracing wires and voltages on the suspension ecu on a 2005 Discovery 3. From the tests we have done we think that it could be either a can bus or a signal issue. I am looking for a wiring pin diagram so that i can check out the wiring to and from the...

ECU is fine as far as we can tell. All relays have been checked and are working and compressor has been changed for a new one and all plugged in. Like i said it was working in a fashion with only the odd issue now and then but now its sat on the stops and not even the compressor is kicking in...

hi all. sorry not been on for a while but me and partner have been fighting with our 2005 Discovery 3 TDV6. We have put it back on air suspension (it had been converted to coils before we got it but due to what it is being used for it needed to be on air) and we are, as you have guessed, having...

Well the air units we have are in good condition (just need a clean lol) and as i said if you press the suspension switch in the car the compressor operates for about 30 seconds and then switches off. so at least the signals are getting through to the pump so hopefully if there are any problems...

Well my partner is an engineer on a country estate and i worked in the motor industry for some 20 years so the knowledge is not the issue. like i said the compressor seems to be running and also the ability to lift the suspension would work better for what my partner does. We have good air...

well its a little awkward. Have just spoken to my partner and its had the normal spring and strut conversion (like a normal macphearson strut on a normal car). This has been done on both the front and the back. Am sure it is the standard conversion. This is the type it has on it now.

No the car has had a coil spring conversion so no air assistance at all. if you turn the ignition on and then press the left switch when you start the car the compressor will power up and then switch off ( i assume because of there being no pressure the system thinks there is a leak and stops...

Hi. its a 7 seater model and yes that is the centre control unit that is in the car. As i have said it was changed to springs before we got i so not sure if anything would have been disconnected or altered because of that. we do know that the compressor seems to be working (well you can hear it...

Hi all just joined here and am in need of advice. Partner has just bought a 54 plate discovery 3 TDV6 that has been converted to springs. He wants to put it back to air suspension as it would be better for his work but is a little stuck. He has checked all the components and found things like...

Have you still got all 4 suspension units?

Hi everyone thought i would introduce myself. Name is kim and for our sins partner and i have just bought a 54 plate discovery 3 that has had a coil spring suspension conversion done on it. Partner wants to return it back to standard (air) and we have a few issues. Will post in required section...
