hmm... Calibrate it and see what happens next.

Did you replace the height sensor?

Just out of curiosity has anyone recently worked on the vehicle? Maybe get some cleaner to clean up the sensor plug/ socket. Tomorrow try and recalibrate the settings on all four corners and see what then happens. I used a tape measure to ensure all the corners were the correct height. You're...

Well this was the week that the fuel burning heater sprang into life on the D3 from earlier in the year! A steam joy to behold! ha ha

When the vehicle is switched on, from the passenger side rear of the vehicle ( just in front of the rear wheel arch ) do you hear the compressor running? I am already suspecting a dead compressor.

I calibrated mine no issue with the AP200, I think your issue lies within the height sensors. Are there any fault codes read from the cars ECU that have been recorded when the suspension is playing up with it's traffic lights?

As above, the 3.0L is prone to failure also, if you have good search around t'web you'll see in various forums that these engines are troublesome. Have a look at something else within budget from the LR big house.

2.0L is made of cheese, these engines have been known to go bang straight off the production line. A V O I D

Pulled the tin tent back from the Llyn peninsula yesterday am back to Cheshire, up and down the A55 no problem,

Almost forgot, new Terrafirma pads on the front. The Brembo pads lasted two years exactly, the Brembo discs have loads of life left in them.

Cleaned the MAF and MAP sensors in readiness for pulling the tin tent this coming week. Hopefully see MPG figures upwards of 28-29mpg.

Updated: now resolved. The reservoir had electrically failed. I replaced it with a genuine LR item and it is now all functioning as should be. Whilst I was under there I had the opportunity to disconnect all electrical leads and pipework to see what the vehicle would do in various states of...

Little update: Had a mess tonight lightly with the computer plugged in, I am absolutely certain now the res in front of the compressor I changed I have not plugged it in properly. The car is venting from the exhaust once switched off like it is supposed to so in my mind it has to be the...

I finally found the 1.0mm size on advancedfactors site after id been on the disco3 forum, I also ordered another fitting kit for the compressor from Powerful UK ( all the bolts, captive nuts etc ) that has turned up today so I am going to pull the new compressor out and replace the compressor...

I've had all the engineers today at work looking for their pitch thread rulers ha ha

Didn't end up going this year due to work commitments, couldn't tell by social media posts whether it was busy or not as the last two years there. The weather didn't look to clever though ( overcast ) I am going to drag my tin tent over to the LROI show in September though as we have never...

No update as yet due to work commitments, D3 is driving around as normal albeit with an amber light at present. Does anyone know the thread pitch of the valve blocks as I am going to replace the voss connectors with push fit for a start off. After this I am going to completely take out the res...

Thanks, just to add car raises and lowers and has not dropped overnight. IMO no leaks, I have changed valves previous. First port of call I am going to disconnect the exhaust from the back of the compressor to see if that affects it in any way. I will also put inline compression fittings...

Looking more into the code this morning I am inclined to say I have probably not seated the connectors back onto the res valve properly and that it is a electrical issue. Thoughts?

Good point, the tank isn't that big after all is it.
