HDC Fault and Fix Land Rover Discovery 3 & 4

HDC Fault and Fix Land Rover Discovery 3 & 4

This fault occurred on on my LR 3 recently.

The display read:
HDC Fault System not available
System Fault Special Programs not Available
And the air suspension dropped to the low position

Firstly I checked the battery which was a bit low. Charging was good at well over 14 volts. The battery was over 6 years old so I replaced it with a new Varta without any effect.

I traced the fault to a loose plastic ring on the steering column, that should turn with the column and operate the steering angle sensor. I have explained in the video the steps I took to repair it using some Areldite epoxy resin.

Mine is finally all sorted, can’t be leave that little play I had gave me all the drama for months now! Tks so much for posting, I stripped and glued and reassembled and a week later still perfect👍

[johnparker]

Excellent advice I've had same problem for a while, after watching your video I checked mine and carried out the repair and now all ok can't believe it thanks so much for sharing this

I had the same problem. Hdc + transmission fault + engine system fault on the screen. During investigation diagnose showed many fault codes including turbo, high pressure fuel pump, egr valves etc.. but later we found the main problem causing these fault codes. It was one of the injectors. There was a fuel leak from that injector. We changed the o-ring and never had any fault message since then.

I had this a few times on my 2007 disco3. Usually a stop and restart will clear it, today it would not. Went into a lower power mode etc, i pulled over and tried the gearbox recalibration because it was saying parking brake fault and the recal always sorts that but it did not clear it and this hdc fault. I left the ign off for about 5 minutes, and restarting was fine and i drove another 30 minutes without problem and got home. I will check if it is the same issue as you have here, im taking it for code diag in a couple of hours, see what that says. Cheers for the video, im happy it was a straight forward fix for you.

Saving peoples asses one video at a time! Great job man!

[davidker]

Thanks for the good vid just had same issue on mine. Plastic collar moving about. Stuffed solid with resin now.

I had the same issues & four garages couldn’t find the fault. Took it to main dealership. They found wiring fault, damaged wire that goes down under subframe to starting motor / damaged. After repair all good.

Hi great video thank you for your time putting this up on YouTube you saved me a fortune
my only problem was undoing the 3 torq screws it took for every to undo them especially the top one wich I could not see
To make it easier to fit them back I welded a short 10mm nut to the screw made it much easier to start them of in blind hole had something to hold onto to start them
then used a small 10mm socket to tighten them of.
thank you so much.

Hello nice video. Was just wondering what should the voltage readings of the battery be while off and on? Thank you very much.

[Gofer]

Ok, I have never seen this fault repair. and am bloody excited to see if this resolves my 8 month HDC fault. I did try full lock to left and right in case the setting was out along with new battery, wheel alignment, new brake switch etc etc but recently my HDC, limp mode, no special programs is doing it 7-10 times a day. I have not come across this check or repair yet and may well be an issue on mine. Question, when you glued the plastic back on to the column does it have to go on a specific spot or does it lock in some where? Or does it not matter as the left to right will centralise the reading?

I’ve been having this problem with my Land Rover LR 3 (2005 )for the last two months and I keep taking it back-and-forth to the dealer and they cannot fix it and my truck will not go over 20 mph, normally happens, more during night time

I have been seeing this fault periodically for months now. Can’t seem to find the source. It seems random and I tend to think this might be it (basically if anything between the related suspension - steering - braking sensors is outside of acceptable range it seems to throw a HDC fault). Shut the car off and start it up and it goes away every time (not very convenient if your cruising).

Will check mine this week and report back - thank you so much for sharing!

[haroonn]

Hey man, I have this light coming on probably after driving it for 30mins doesn’t come on right away? Just thinking if it would be the same issue and hopefully as easy as it is to fix.

[eizuke]

I have the problem that my wheel straight but in 4x4 info it little bit to turn left. That also the same problem and solution the same as you ?

[bikelifemark]

I had this fault an fixed with glue on the colum but left the truck for about 4 months and now it’s comin back on the problem only comes when I drive it over 10 mph wen I take key out an back on the fault goes will I need a new battry ??

[guillermomorrisonromero]

I have a serious problem with the suspension my Range Rover Sport Supercharged 2007. I have all the time following alarms on: DSC, ABS and Dynamic Response. My technician says that apparently there is problem with the rear locking differential shift motor. could be true?? I will really appreciate your comments.

[pistonhedd]

Before you fixed it, did it stop the engine from turning over/starting - kind of acting like a dead mans switch?

[sarkavlnasova]

Hello. I'm just getting ready for the repair, but today I found out that the engine does not rev up when overtaking and smokes black. The engine light does not come on and the fuel consumption is normal. I have a 2.7 tdv6. Thanks for any advice.

[Karooseun]

Exactly the same fault showing on my Range Rover Sport TDV8 2009; just started showing this yesterday; the battery is fine and nearly fully charged and the alternator is ok; the OBD Tool does not show any error codes; I will have a look at what you described though;

[stormbg]

Hi man...so I've been having a problem on my landrover...same model as yours so basically it can't climb small hills or bumps when it is on D...even if I push the accelerator to the max...any tips on this?
