Hi, My Soft-Dash hit the deck yesterday! :(
Guess it didn't fancy the trip to the Sort-Out today! :shock:
Wish it had gone last week as was in Hillsborough
visiting the out-laws....
I'm in Essex too so, following with interest.....
P.S. Gotta spare Multi-meter if you need one Dave..
Cheers Barry :D

--- Quote from: "Range Rover Blues" ---Right, if you found a 30 amp fuse under the seat then keeping it company are a large relay that gives the EAS a 30 second delay to self-level after turning off the ignition, a 5 pin relay that runs the warning light on the dash and a 4 pin relay that runs the pump itself :)
THis relay needs checking, even if it's just to see what's going on.
The pressure switch is if I understand correctly open circuit untill the pressure reaches 10 bar nominal, it stays that way 'till the pressure drops to 8 bar.
So if you disconnect it the pump should run. Sounds wrong to me as there is no failsafe in that logic, but that's the way I read things from the manual.
The temp switch is better, it goes open circuit when the pump clears 120 degrees (ouch) and it goes to earth, so you need to check the continuety of the red wire on the motor to earth, if the contact is broken the pump won't run, so try shorting the red wire to earth.
If you are still struggling then I have found the pinout of the ECU for you, you will have to check through it in order to check what's going on. You can also use it to manually inflate the EAS if you can get the pump to run.

Yeah I saw the relays and a 15amp fuse(which was ok)today.
Will check out the relay soon.
So if I just earth out the red temp wire then it should run the pump providing nothing else wrong :?:
I will send you an easter egg for all this help :)

Yes, if it's the temp switch that is fried then short it to earth and the EAS should run the pump, assuming the temp switch is faulty. You can check it when you get your loverly new meter :D

Range Rover Blues you are a diamond..I earthed out the red/orange wire and its back to life... :D :D :D :D :D :D :D :D
Can it be left like that indefinately :?: :?:
I have noticed the compressor vibration through the car more than before but I put this down to the change of compressor and the rubbers (and maybe overtightened the fixing bolts).. :!: :!:
So PM me your address and I will send you that easter egg :wink: :)
