Hi again Forum users!

Went out to move the RangeRover and found it down basically on its knees - lower than "access" height - sitting so low that it cant be moved. Tried starting it and hoping it would rise, but no go.

I guess 1st stage is to get a cable from Datatek - any other diagnostics I can do meantime?

Thanks

Took a while to find the howto, but got there in the end, thanks Wammers!

Will be spending tomorrow faultfinding, after a look at the videos on rswsolutions.com I begun to feel a bit more confident diagnosing the fault. Went out tonight (in the dark, no electric in the shed where the suspension gave up) and after a few minutes it became clear the compressor wasn't running. Then, just out of the blue while I was touching it - it began to run, so I left the drivers door open and waited for it to fill the tank.. and waited.... and waited......... and, yes you guessed it.. waited some more.

While waiting I screwed the air filter off and checked it was clear, then put my finger over the inlet and blocked the hole, there didn't feel to be a lot of suction for the first 2-3 seconds then it started to suck harder, I didnt want to put stress on the pump so only held it for about 5-6 seconds. I also noticed the compressor motor body wasnt locked tight to the pump body. There was a very slight amount of play between the two. - is this normal?

After about 10+ minutes I could feel the pump end of the compressor start to get a bit warm, so decided to try closing the door and see what happens...

It lifted to the correct height!

After moving up and down a few times it begun to struggle a bit, so I let it idle for a few minutes with the door open and then up she went again.

My thoughts are that I have a series of faults, a worn compressor piston seal, slow leak at some unknown location and possibly an intermittent compressor motor for whatever reason. Will diagnose further tomorrow, the suspension drops over a period of a week or sometimes less. (I keep the battery disconnected when not in use due to RF receiver issue)

Any feedback meantime is very welcome. and Thumbs up too for Datatek who has been very helpful with the EAS cable.

There should be no play between motor and pump head. You need to tighten that. Sounds like piston seal is on it's way home. Change it and check the valves.

I'm in a similar position to you (that position being on the bump stops). I changed the piston seal and liner but the compressor motor has worn out, so waiting on a recon compressor to arrive and fit. Mine did stay up so hopefully no leaks. Sounds as if you do have a leak if its slowly dropping; time for a spray bottle of soapy water. Recon compressor/pump about £90 with the p&p. Wammers and datatek are the guys to ask when it gets to head scratching moments. Good luck with it.
