Just to update the thread, ive got this fixed, it was an earth fault inside the BCM. Had to wait for a new BCM from range rover as they were on back order, but glad to say its back on the road. The 2012 doesnt have a LCM the lights are control by the BCM which is located within the back of the...

Says it locks its self to the first car you use it on so cant be used on any other car, not really something i would want it to do as also got other cars that id want to use it on. Gonna take the car to a local diagnostic guy i know see what he comes up with.

Yer looking like im gonna be buying a new one mine wont read much on this year of them, whats the best one for a 2012 tdv8? Done some more digging around in the car found it is 100% not the cluster i swapped from 1 side to the other and proved the cluster so its def within the wiring or lcm. I...

Not the thing i wanted to see ;-)

Not found any signs of water ingress yet, its lived its life in a garage so i would hope water ingress wont be the issue. Also should have said that nothing came up on the dash it was only my missus saw it as i pulled off the drive

Yer i dont know either, its a JLR rather than BMW LR but i dont know when the cross over was or if they used the same electrical parts

I also assume that theyre not fused on each side, found F6 controlled the brake lights as offside and top light work fine until pulling F6, The nearside did come back on at one point when i had hazards, fogs, side lights all on at the same time, but stopped working again and hasnt come back on since

5 pins Ground (black common to both side although the connect is inverted from side to side), side light, brake light, fog light, indicator. Dont think its a switched neutral system as when u check the voltage at the plug on the side light circuit im getting 14volts on the pins in the plug

Yer its an led cluster

Afternoon all, got myself a l322 2012 tvd8 couple of weeks ago and the nearside brake light has stopped working, took the cluster out and it appears to be a sealed unit on these rather than the old unit where you could replace the bulbs in them, i stuck a 12v supply across the pins 1 at a time...

All fixed, drove the car up n down the road and air suspension cycled as it should, just got to put the whole thing back together now. Thanks for all the help.

Check everything works on it, take some overalls and get right under it to check the underside for any leaks. Check every bush you can see, cycle the air suspension a few times if its slow walk away. Check for damp carpets & bad smells, Sounds stupid but i always look at the tyres 4 (on any car...

Can only be that, although the air suspension wont go up now. No fault codes and i can hear the pump going on it. I know what ill be doing today.

Ive no idea how but its come back to life, i was pulling fuses to see what circuit controlled the brake lights and was going to go from there, pulled 9 and 17 which turned the brake lights off and the car came back to live with a bunch of fault codes which clear by going lock to lock on the...

Yer ive got 1 on a laptop somewhere but i need a starting point. I recon its a short somewhere possibly in the purple plug so just cleaning that out in the hope its that, i cant find anything else thats got wet anywhere and the car wad fine when i parked it up yesterday evening

Hi yer i opened in manually, the tool for it is in the boot which i couldnt open as i disconnected the battery (got dog cage in so no access from rear seats either). Got it open with a long 4mm allen key through where the sunroof switch lives, cleared them with compressed air which blew the hose...

Thanks for your replies, my OBD reader needs the ignition to be on to read the codes so need to get ovwr that hurdle 1st :-( Wheres the ecu in the car? I always thought it was under the bonnet on the diesel. The fuseboard is dry, ive taken the ecas ecu apart and thats bone dry which sits to the...

Morning all, was awoken in the early hours this morning by my l322 3.0 diesel (2003) alarm going off on 1. Couldnt do anything with the key fob to shut it up. So disconnected the battery. At a more resonable hour i went out to investigate, found when i reconnect the battery the brake lights are...

Cheers for the replies, thats exactly what i was looking for with no joy, looks like a nightmare of a job to do. Father in law said it was squealing before and i heard it saturday when he left ours but yesterday it wasnt squealing at all it sounded like it was running freely (like it was...

Morning, my father in laws 2006 TDV6 RRS has developed the squeal of death from the electronic parking brake, yesterday it jammed on and the car was stuck fast, We've got it free using the emergency release under the centre console. Ive done some searching and can get the gears for £30 but...
