Hi guys, my 2007 2.7 hse is playing up. Whenever I accelerate and turn I hear a clunking from what feels like right underneath my seat, it's worse when turning left. Turning the wheel at standstill doesn't do it, it only seems to be when I accelerate into a corner. That's the first thing!
Next, my suspension is faulty! it's in access mode and won't lift. New compressor required?
For those interested in driving yours in access mode because "it looks cool" FFS don't!! not the comfiest or quietest drive I've ever had!!
Any help or advice would be much appreciated.

Best not to drive in access mode too much unless you plan on buying 4 new tyres.

I would leave it sat up until you sort out the suspension, it's not guaranteed to be the compressor but it's probably a good place to start. Does it throw any errors on the dash ?

The clunk could be a ball joint, a swing arm bush, a drive shaft or even a diff, get it on a ramp and swing on a few bits.

Yeah it comes up suspension fault on the dash also special programmes not available.

Does the 4x4 screen show any red bars over the wheels? One of the failures that causes the vehicle to drop on to its bump stops is a "cross articulation error". This occurs when more than one height sensor gives a spurious reading. The fix can be as simple as a calibration of the height sensors. Don't drive it too far as you have no suspension at all - it's on its bump stops and that's why it feels so uncomfortable! The reason you get the "special programmes unavailable" warning is as a result of a cascade failure; the Terrain Response system can't work correctly if the suspension can't be raised etc. 2012 SDV6 - it's missing a couple of cylinders

Makes sense it's on its bump stops. I'm pretty sure you can't drive normally in access mode anyway, the vehicle raises itself to standard above a certain speed IIRC.

RRSTDV8 funny you should say that, a red line is over the drivers front wheel and as been for a while, I never knew what it was I thought it was because my drive is uneven!!
It drives normally in access mode but it's very noisy and you feel every bump and I mean every bump!!

One last thing, it dropped to acces today because I pressed the button to lower it, it just won't come back up again.

You need to get the height sensor sorted before you do anything else. Also, check that there isn't anything in and around the suspension in the driver's wheel arch. I wonder if the noise you mentioned is something broken or fouling on the suspension and preventing movement. 2012 SDV6 - it's missing a couple of cylinders
