Suspension / HDC / Park brake / Transmission fault hell
I'm wondering if any of you clever chaps can put me out of my Groundhog Day of discovery issues.
So first some history.
Some time back we used to get an intermittent suspension fault. It didn't affect anything, and turning the car off and on "fixed it". That hadn't happened for some time.
I then started to get really poor performance below 3000rpm followed by a puff of black smoke and then off it went. I had the EGR valves done some time back so thought it couldn't be that and there were no errors like before. But I thought I'd fit a blanking plate set to see, and sure enough no issues after (I was expecting a light since it's a 2008 model)
I then had a remap done, no issues, much better performance.
And now for the last couple of weeks we are back to the suspension fault and a host of others as per the title. They occur intermittently, sometimes together and in different mixtures. Off/on fixes still but it is occurring more and more often.
I have read the forums and so far tried:
-new battery
-new brake pedal switch
-suspension recalibration (after booked in with specialist).
I was hopeful it was the last one but alas, it's just happened again.
I'm running out of patience with this car. It's not the cost but the inconvenience. We are due to do a 400mile trip next week!
Can anyone tell me what to try next? The specialist said if the suspension reset doesn't fix it we will have to take it to land rover and I would rather not do that!
Thanks all

Try the battery and the brake pedal switch.

You need your codes read, without codes it could be so many things... You're in Kent so Geoff. can't be far away?-------------------------------------------------------------------

The codes have been read by the specialist but I don't know what they were, will try to find out. Thats when they did the suspension reset. I know there were "lots of them"!

I've been looking for 3 evening now for alternatives after I sell and can't find anything offering the practicality, space and spec of the disco. Nissan Pathfinder is about the closest.
Is the discovery 4 any more reliable? Is it basically a D3 with a facelift and retrim?

I've had many similar issues to you. I have diganosed and replaced brake switch, compressor dryer cover, LPFP and HPFP all of which individually over time have caused the sort of symptoms you describe. They all throw different codes so without you being able to tell us what the codes are we're really shooting in the dark. I'd love to help but with just symptoms it's nigh on impossible.-------------------------------------------------------------------

Am in a similar situation and have been for nearly a year
On the positive side... The Dealer has now replaced the Transfer box control module (it was corroded) and done 70+ miles of road tests in various driving types on multiple days without a re-occurance... a £450 fix, much better than a £1550 HPFP fix!
Expecting to collect the car on Monday evening, I'll report back....

Hi all
Ok so the fault code as read by the garage:
C1A13 pressure does not decrease when venting gallery
C1A00 control module
They said they tried the suspension reset due to the first one and are hesitant to start replacing parts when the 2nd one is there, and Land Rover will need to read it to get more info.
They didn't charge me though since it wasn't fixed which is jolly decent of them.

Earth straps cause those faults too mate. There is am=n earth strap to the left of the ABS module on the left side of the engine bay. Its tucked away and has a dome end nut on it. Thats was the cause of my issues. I checked and it was loose, tightened it and fault lights went out. I had to reset the fault codes with my IID tool afterwards though. Hope that helps.

Thanks I'll check that out.
I'm reading somewhere about diagnosing suspension faults by pulling fuses.
If it helps at all, I've found that before the fault occurs I am not able to raise the suspension. The switch does nothing, nor does it produce the fault. However if I try and lower the suspension it immediately gives me the suspension fault.
That leads me to conclude its more likely something to do with the suspension than transmission and everything else it mentions.

Earth strap checked and looks fine. I checked fuses and they looked fine too. Pulled some but wasn't sure what difference in behaviour I was expecting / looking for.
The fault can be reproduced at standstill by just attempting to lower the suspension. Choosing special programs doesn't cause anything.
I assume the fault occurs while driving when the car attempts to adjust the suspension slightly - if that adjustment is a height reduction the error occurs. Explains why it is random on each journey and generally occurs less on motorway vs backroads or uneven ground.
So what does the collective grey matter offer?! Does pulling a particular fuse stop the Auto height adjustment - is it 35p behind the glove box?

The fuse pulling you refer to is used to diagnose overnight sinking not the central/compressor issues that you have.
Try doing a forum search for the fault code. For example this thread talks about a wiring fault in the NSF wheelarch that can cause similar issues?

Trust me I've been searching but seems like there are a lot of possibilities! That link doesn't really give a solution. Replacing the compressor is a likely fix it seems but I don't think it's that because sometime it drops and can get back to normal height just fine after a restart.
However given the symptoms and some more reading I think the exhaust valve makes sense in terms of the inability to lower and the fault saying the pressure does not reduce.
Trying to find a guide for just doing the valve - does the whole thing have to come out either way? If so I may as well do the whole thing.

It's pretty tight to work on the compressor in situ, I replaced the air dryer cover without dropping it down but I confess that I couldn't say with regard to other components. The biggest issue is seized bolts which is why I gave up and did it with it mounted.-------------------------------------------------------------------
