No help at all, but is that 300,000 miles on the original engine
Andi.
Yes it is, oil and filter every 7500 miles, original injectors, belts changed on time every time. Still got the original starter motor and water pump. No leaks , no smoke and it still averages over 28mpg. Works hard too, as it tows a plant trailer most of the time. In fact, apart from servicing, it has never had a spanner on it.2011 D4 HSE, it'll be nice if it ever works!

Front suspension was down on the stops this morning Off out there to read the codes again. I don't hold out much hope that there will be anything new there. I need to sort this as I need to get another five years and 200000 miles out of it 2011 D4 HSE, it'll be nice if it ever works!

Ran the diagnostics again this morning. Only one fault code U2000 motor temperature. Algorithm based intermittent fault. Disco behaving exactly the same but the fault code is a new one. None the wiser.2011 D4 HSE, it'll be nice if it ever works!

Hi
There’s got to be a leak there for both struts to drop , as after pulling F26 which is a 20amp fuse I can’t both front struts leaking
I had leaks all over the place on mine and in the end I used isolating valves and pressure gauges and tested each line, valve blocks etc
Even put in a pressure gauge and isolating valve before the front valve block so I could tell if it was the front or rear leaking
Hopefully the more experienced members will be along to help

When you fitted the new front airbags you didn’t unscrew the valves on top to get the pipe in did you?
As it’s a push fit, and could explain why both fronts are dropping

Is the isolating valve still fitted? Did you fit it after you realised you had a leak, or prior to? (Some owners fit extra valves to isolate airbags as a preventative measure..)
Some of the plastic T-off's leak.2011 MY D4 HSE

No, only undid the pipe fitting. That has all been leak tested and its airtight2011 D4 HSE, it'll be nice if it ever works!

The fault, whatever it is, only seems to affect the front struts as the back two never move except when I raise or lower them. Got a thousand mile trip to do during next week with the trailer on so I can only hope that it survives that without getting any worse. Next Friday's date with the agents diagnostic gear seems a long way off. 2011 D4 HSE, it'll be nice if it ever works!

Hi
Fitted them after I realised I had leaks , the suspension useto drop one side , then the back etc, bubble tested everything and only found the front struts leaking around the middle when I sprayed them , yet continued to drop
So ended up disconnecting all the lines and testing them one by one and vacuum tested the valve blocks
At the end I replaced
Front struts
Air tank
Front middle and rear valve blocks
Air compressor because I was burnt out keeping up with the leaks
Disccant was everywhere so blew all the lines out
This was the valve I used with the pressure gauge , was able to turn it round so could see what side was leaking , ignore the yellow pipe, that’s for the aircon

Indeed and understand ref the diagnostics will be interesting to see if it shows anything , will it drop in normal height but not in off road height please
Hope u get it sorted out and is a simple fix
Plse let us know how u get on and they find it for u
Had to make a fifty mile round trip yesterday, no trailer this time. After about three miles the suspension fault light came on. I pulled over and immediately plugged the fault code reader in. U2000 again. Cleared it and drove on another ten miles before the light came back on. Pulled in and switched off. The front dropped right down within five minutes. Restarted and set it at off road height. Straight back up no issues. Set at normal height and continued on. Got to my destination with the light on but the suspension at normal height. Raised it to off road height and left it for five hours. Dropped a little at the front but not much. Drove home without incident and no warning light. Left it at normal height without fuse 26 in place. Down on the stops at the front this morning. No fault shown. Roll on Friday 2011 D4 HSE, it'll be nice if it ever works!

This is starting to sound like the height sensors or wiring.
On the center display, select 4x4 (arh that's probably not enabled, but you can with iid somehow)
Anyway. Above the tyres ate bars. If the bar colour goes red it means out of range.
Next time you have the fault watch the display. If the wheel is bouncing up and down and then goes red you know which sides at fault.
The other side is probably being adjusted to try and level.
All symptoms don't match this, so don't rush and replace sensor but it's worth enabling the display and watching it.
Thanks I'll check that out in a mo2011 D4 HSE, it'll be nice if it ever works!

Give you a rough Idea what it looks like
Sometimes the wheel bounces up and down like a joggers breasts.
Thanks for that, just checked the Disco out and its all fine. Roll on Friday!2011 D4 HSE, it'll be nice if it ever works!
