As above really folks. Damn annoying. I've changed all the things like brake switch etc. Diagnostics haven't thrown up any problems. It's really sporadic and comes on literally when I start he engine. Can sometimes not rear its head for weeks but sometimes pop up for consecutive days.....any ideas gratefully received!!!! It's driving me mad!
Oh it's a 2008 range rover sport...

Guessing that HDC in this case is Hill Descent Control, could it be the RR version of the LR Discovery's "3 Amigos"?

Usually cause by water ingress, failed ABS sensor or dodgy wheel bearing.

I'll look into those as I think the disco and sport are the same underneath the skin

Are all the bulbs working and good quality ones?
Have known cheap bulbs to cause issues. Brake bulbs seem to upset them the most.

How old is the battery? A dying battery or alternator can also throw up random lights.

New battery a.d I've replaces all brake bulbs with good ones also the brake switch I'm hoping it's a wheel bearing as just this week ones started to be a lottle rumbly.....

Has it had an alignment done? And the steering sensor not reset?

Or any of the abs sensors changed?

[silverback mike]

No alignment or sensors changed......and weirdly on my journey home after work no warnings on.....really annoying as I guarantee if it goes into the garage again the warnings and messages will disappear. I do think I need a wheel bearing though so may get them to change the and sensor. I'm gradually ticking things off the possible list!

Has it been to a Landy specialist for a look?

The Disco3 site has a few causes, I’ve asked about the usual ones.

I would try and find a good specialist to hook it into their machines to see if they can help narrow it down without throwing parts at it in the hope one is the right one as thatncan be expensive.

Whilst the standard response is always hook it up to diagnostics, There is diagnostics and diagnostics. Has the Independent got an AutoLogic? Not all garages have them as they are damn expensive.

However, even an AutoLogic will just highlight the component at fault when sometimes its a fault in the signal going to the component highlighted in the diagnostics.The D3/RRS are complex beasts and it would not surprise me that this fault is being caused by some corroded wiring and the weight of the body and the weather will affect the fault appearing.

I have had this fault and it turned out to be a very bad repair/bodge job on the wiring to the valve on the air tank and the front valve block.

I'll check whether they have the correct diagnostics... thanks for the pointers folks!
