ABS, brake, HDC and transmission failure
Picked D3 up from dealer last night after having following work done:
105K mile service inc cam belts and ancillary belts
Brake fluid change
Transfer box oil change
Replaced a front mud flap (no goodwill here - £8 labour to change. 2 screws = £8!)
Just over a mile away while stuck in traffic the following occurs:
ABS and brake warning lights come on
‘Transmission fault’ message
‘HDC fault system unavailable’ message
‘Suspension lowering’ message
Suspension warning light on
‘Pull over and stop safely’ message
I found a place to stop, switched off, left it for a couple of minutes and then started it up again. Everything fine and suspension raised ok. Drove the last couple of miles home very gingerly.
Additionally the accelerator feels different. It seems to be far less progressive than it was, with more play in the pedal travel before the engine increases in revs and then the response seems far sharper.
I know that one of the front brake pad warning sensors is broken (advisory item picked up on service) but surely this shouldn’t cause all of the above.
Have phoned dealer and they can offer no explanation for above. I have to get the vehicle to them for them to investigate. I’d like some idea of what is wrong or the possible causes. Not entirely happy with the treatment from the dealer (see dealer feedback) so the name of a good specialist as well!
I have got to admit the suspension lowering fitted my mood exactly, happy to have the vehicle back and serviced it is very deflating to have all those errors in quick succession!
Have you checked your brake light bulbs? A failed bulb can cause a whole load of messages together.Previously:

Thanks RM.
It's the sort of thing I would hope would be covered in the service but I guess one could have gone in the 10 minutes of driving having left the dealer. Will check.

ABS sensor, or broken wiring at n/s/f wheelarch

All brake light bulbs are ok.
Thanks Mikey.

I had an identical set of random fault codes and running problems from a dodgey battery. all solved by replacing it "its probably a virus, you'll be right as rain in a few days and if you're playing sport try to favour the other leg"

I have a 54 plate D3 in at the moment with this problem...back right abs sensor flagged on the diagnostics. I changed it but still the same. I checked the wires and found no continuity on the white wire from the sensor. I found a break in the wire 2 inches back from the grey plug behind the left hand inner wheel arch. The copper in the wire had turned to copper sulphate powder.
........A failed bulb can cause a whole load of messages together.
I know this failed or intermittent bulb condition has been blamed for a whole bucketful of issues on here
But I still cant get my head around the fact that brake lamps go on & off anyway.....Normal situation...the switching action from elsewhere.
If one bulb fails.....it fails.....one lamp lights & the other presumably doesn't....OK you may get a flicker as it fades & fails - the bulb element breaks....maybe flickers a bit
Are we saying that that this flicker can cause the issues that are reported i.e. the transient voltages (way above the vehicles 12V) are generated by bulb failure & not by the actual switching action of the break lamp switch?
It beggars belief that just this one circuit & a failing bulb can be thought to cause so much grief & that the Land Rover Disco electronics are that feeble to be affected by this....doesn't bode well for vehicles in their "after-life" i.e. vehicles way beyond warranty with old wiring that may have corroded connections, poor earths, damp etc.
Questions:
1) have newer vehicles got surge diode protection on this & other circuits?
2) does the same thing happen on RR sports?
3) there are stacks of things being switched electrically - some with far higher current than the 21watt brake lamp bulb - surely these will be more a culpritBREXIT - done properly.
Right now ...We need Government - not Politics
Save the Dipstick Flagbearer-keep it simple, less likely to fail campaign-agenda items:Starting Handles, Acetylene Lamps.

D3 HSE-perfectly formed, passenger friendly...has real DIPSTICK
Jag XK-but sadly no DIPSTICK...HUGE design fault
FL2 has DIPSTICK..."real comfort in rear seats"
VW Golf wondermobile (?)..has real DIPSTICK
Morris Minor..original DIPSTICK technology..and a real KEY.
I think the brake bulb errors are caused by the broken brake filament touching the other filament in that bulb. More a problem with cheap bulbs as far as I know.Previously:

Dear quantumjohn
I hope for you that one of the above options will solve your problem.
I had the same symptoms while driving in low gear and max height and the car was issuing the warning, turning off the terrain response and few second later lowering the car to the floor.
It turned to be the small electrical engine which engaged the diff lock!!! This small part which looks like the starter elect motor cost near to 2000 usd.

Thanks everyone for the responses. This is a great forum.
I've done another 10 miles today and the issue hasn't occured again so it suggests an intermittent issue like a broken wire.
The battery looks new and it appears the previous owner was in a rush to replace it. It's a larger range rover battery so the plastic box top won't fit over it. Probably took what the dealer had in stock. The connections appear tight.
Do you think the dealer would take some responsibility for it if I went back to them?

I doubt the dealer would take reponsibilty for it if they didnt fit it...
As said though, my money is on the wiring being broken/chaffed behind the n/s/f wheelarch. Common fault on them

HI John
Welcome to the D3 family.
What Mikey said make sense hope you will not suffer more that. Don't stop until it will be solved because it will hit you at the most uncomfortable moment

Danny, Mikey, thanks for the pointers.
I will be going back to the dealer - see if they will take some responsibility for the fault - especially as I have found it is over filled with engine oil and there was a tool left under the bonnet
