Suspension Problems, doing my head in .

[Fatso]

The suspension was lowering the front on my 2007 RRS overnight , could not find any air leaks so decided to replace the front valve block , on initial start up the feed preasure line blew out of connector with an almighty rush of air for a few seconds then stopped .
Second go and on start up have the rear raising as normal and the front raising very slowly with message on the dash saying this as well , also on going to off road height it stops , saying it is in extended height and to remove or reset what ever it is hung up on also this info on dash , and still raising very slow and "times out " to cool before carrying on don't think I ever got to off road height in the end .
Good thing is did not drop over night but seem to have more problems than I started with . Can anyone throw some light on this , do I need to do anything else with the new valve besides just fitting it ??. Could the new valve be suspect ?? . Thanks for any info .
Took for a drive and got bong with C1A20 Suspension Fault , normal Height Only , Checked with Faultmate and got C1131 air supply failure , and something about plausability or some such thing . should have left well alone me thinks .

If it thinks it is at extended when raising a sensor is suspect or it needs a calibration I would think.
Is it possible you touched the wiring to one of the front sensors when getting to the valve block?
I have seen similar problems when one of my GOE rods wasn't changed back from off road and the others were. It couldn't level and kept trying and would overheat or fault.

Is the sensor near the valve block ? funny thing is the rear is going up and down as normal ,its the front that seems to play up .

The sensors are in the wheelarches. If you've taken the wheelarch liner off to get to the valve block, you may have disturbed it.

Do you have a fault reader of some sort?

gday , did not take wheel arch out just turned drivers wheel out and lifted botem of wheel arch away to get at valve block . checked with faultmate and findings above in first post .

[Geedublya]

OK sounds like you have an air pressure problem at the front as it does the rear first and then the front. Maybe you have a stuck valve.

Let me google that for you (http://lmgtfy.com/?q=C1131+air+supply+failure)

Let me google that for you (http://lmgtfy.com/?q=C1A20+Suspension+Fault)

Try those two.

Gee that's a neat trick , have been googling , will keep looking . Thanks

So you did. I must have missed that.

[EDIT] Ah, you added the info after I read it.

Sorry I've been waiting to use it and you were the first chance.:angel:

Could have the airlines got mixed-up when fitting the new valve block?

[Fatso]

Just put old valve block back on , still the same with all the probs I did not have at the start . Think it may have something to do the preasure line blowing out at the first start and buggered something in the supply valve or the compressor . Looks like a trip to the doctor maybe .

will double check but pretty sure they ok .

[Marmoset]

It could just be an air supply problem, car raises the rear first then realises that there's not enough air to do the front, compressor works overtime to compensate and gets too hot. Is it the original compressor, it could be the dryer is blocked and it's only now becoming evident with the wet weather.

[Fatso]

Does not want to raise the front at all now , still says it is in extended mode and reset suspension if clear something like that . maybe compressor or height sensor . Strange all this started after changing block valve .

Only had the car 2 yrs but believe it is the original compressor .

[Marmoset]

It could be worth taking the compressor off to check the dryer, have a look over on Disco3.co.uk, as if the dessicant breaks down it can block valves.

Some people have taken them apart and cleaned up the dessicant inside it or you can buy a new dryer for significantly less than the whole compressor.

As here:

DISCO3.CO.UK - View topic - How to 'repair' air compressor and fit new air dyer (http://www.disco3.co.uk/forum/topic101868.html)

will double check but pretty sure they ok .The line from the compressor goes to the bottom of the 2 that are on the side of the valve block. The top one heads upwards to the right air-spring whereas the bottom one from the compressor is horizontal.

All good , think it is something to do with supply valve near comp or the ecu has thrown a wobbly , as I think I can hear the comp running and it also has slow raising but the car does not raise at the front , and comp has cool off periods . Hate to see another landy on a flat bed but may have to be , to far to repaire shop to drive on front bump stops .
Or have a go at taking comp out and inspecting it myself if back will permit .

No not a flat bed bloody hell just add to all the people on other sites saying i work near a land rover dealer and see heaps of them on trucks go past haha.
But it would be bloody rough driving on the bump stops bad enough in access mode under a low building!

[Fatso]

Landy all ok now , turns out the new valve block was a dud , **** happens , and the original valve block had a digital problem when it was put back in the car , The digital problem was me cross threading the supply line voss connector to the original valve block . Ah well we live and learn .
