Have a mysterious intermittent fault on my 2010 Disco 4.
Had it for nearly 1.5 years now and it’s only ever done it 3 times, twice of which were yesterday.
Turned left into a petrol station and the car made a slight...shudder, or very slight vibration I guess you’d call it, and then I got the following warning come up on the dash:
- HDC not available - System Fault
- ABS Fault
- Park Break Fault
- Emergancy Break Assist Not Available
It might just be coincidence, but it always seems to happen when turning left.
Turning engine off, and immediately back on again clears it. Tried to replicate on way home again yesterday, but no luck.
Anyone else ever experienced this, or got any clues as to what might be causing it?
Cheers,
Rob[/i]

Wheelbearings OK? although I'd expect it more often than 3 times in 1.5yrs

Yep, fairly certain wheel bearings are ok.
The vibration is only for half a second, not continuous.
Would wheel bearings also set off all those errors...?
Cheers.

My neice now has my 2005 D3, it developed the Xmas tree lights a few months ago, I was into everything fearing the worst and the only fault code I could find was the F/O/S abs sensor, so I changed it, no difference! I did notice very slight wheel bearing play in that wheel (and I mean slight).I was pulling my hair out checking connections etc etc and decided that the wheel bearing would need done for the MoT anyway so ordered one up. Fitted the new bearing and several 1000s miles later no problems
I didn't initially think it would have had anything to do with it as I'd previously done the nearside bearing a few years before as it was really bad yet no warnings of any type
These Xmas lights you are getting may or may not be related but the best thing to do is get your codes read and take it from there - best of luck and let us know how you get on

Hmmm - Could well be the ABS sensor - Searched a few threads on here and a few people have mentioned the same errors etc.
Seems to be a permanent feature of the vehicle now - Even on startup it's lighting up the dash with the errors, and no raised suspension etc.
Any ideas how easy they are to replace/how expensive they are??
I haven't been in the area long - Any able to recommend a good indy in the Rutland/Leicestershire area?

I've had this happen a few times now
First time I didn't have a clue what had happened. Turned out my independent specialist had updated the CCF file to turn on the towing electrics (I had told him I was fitting them) but before the wiring was physically in place. Had to disconnect the battery to get it to go away even after putting the CCF back to standard
Second time was the same idea. Turned on the wrong Xenon setting for my new 2014+ face lift lights and the same thing happened again. This time I updated the CCF back to normal, went through the start / stop / start procedure twice and it went away without touching the battery.
So my thoughts would be that something somewhere in the electrical system has gone wrong to upset the car. Might need to check for fault codes2013 Discovery 4 HSE Lux | 2001 Defender 90 TD5 | 2007 Prodrive RB320

Hey Ross,
Thanks for that - that’s quite interesting!
Since owning the car I’ve had both the towing electrics turned on, and have upgraded my poverty spec halogens to 2014+ xenons, although, I didn’t have them activated properly at my local Indy garage...they do work, but not as they should. (DRL’s don’t come on with ignition, only as dimmed side lights).
I’ve recently been playing around with some of the electrics for my sat nav installation, but only simple stuff. Adding aux cables, reversing cameras etc. Nothing major.
You say there’s a way of resetting stuff by taking the negative off the battery etc? Would that help at all? How would one go about doing this?
Tediously haven’t got a fault reader yet, so will have to dive into a local garage and see if they can help, unless anyone near Oakham has a fault reader that could help at all?
Cheers for all your help!

Hey Phil!
Is it an easy job to replace them?
I’m looking online, but can’t seem to find much about replacing it.
Would I need the fault codes cleared once having new sensors installed?
**EDIT**: Have ordered two new ABS sensors - here’s hoping it’s not too complicated to fit!

Morning!
Pretty simple to do I seem to remember.
Sensor is in the hub, unbolt the sensor and follow the cable till you get to the "other end" where it plugs into the car.
Then just replace.
Some info on the following link (Bodsy brake bible) , see page 21 for a pic.

Oh, and I dont think you need to clear the faults-they will stay in the memory but the car will be better!

The battery lives under the big plastic cover just in front of the passenger side of bulkhead, inside the engine bay
Take the cover off and unbolt the black cable assembly. 13mm spanner I think from memory
Take it off totally and hold it there for about a minute (so that it can't touch anything metal) then replace. might spark a little as you put it back on but that's normal
Turn car back on and see if all the lights are gone. The first time I had the issue with the towing electrics (before I knew that was the problem) that fixed it.
You'll need to reset the clock but everything else should be retained2013 Discovery 4 HSE Lux | 2001 Defender 90 TD5 | 2007 Prodrive RB320

Apologies for the late reply - I hadn't seen you'd replied! Will give this a go now and see what happens.
Stay tuned!
***UPDATE***
No luck. Absolutely nothing changed unfortunately. Will await delivery of new ABS sensors and try again!

Right, slight update.
Sensor arrived today, so thought I’d have a poke under the car...
Sensors all feel ok, but haven’t taken them off yet.
What I DID find however, was that part of the loom was frayed at the point behind the front passenger wheel, a inch or two before the loom splits to take two wires off to the passenger front height sensor.
I fiddled with the wires, and then started the car. Errors have now changed and only shows:
Suspension fault
Terrain Response Special Programmes Not Available
There is also a low tone, short beep when I start the car...
Am going to fix the wires and see if that helps.
I’ve attached a photo (as best I could get) below. It seems to be two plain white wires - does anyone know what these wires do??
Also, it looks as if someone has cut into the loom here, or does it come from the manufacture like this??
Cheers all,
Rob
***UPDATE***
Discovered that the loom was all munched up there because the tyre when on full left lock was rubbing against the chassis rail/the loom, so have now patched back together the loom and moved loom out of the way of tyres. That explains why it was happening when turning left at least!
All errors gone, apart from one: the terrain response functions are still unavailable.
Do I need to have this fault cleared for it to go away??
