| HDC, DSC, Brake & Transmission Fault Lights Amber |
|
Hi,
The HDC, DSC, Brake and Transmission Lights are all coming on together intermittently. It appears to happen under braking or going over bumpy ground. The lights clear on re-start (so far...). I haven't had the difficulties outlined by previous posters such as fuses blowing... yet.
Any thoughts....
Thanks Eddie

Eddie, that is most definitely the BRAKE SWITCH behind the brake pedal, behind the panel. 
Nip in to yer local LR parts, if yer have a good relationship with their service guys, take 10 mins and does'nt cost much £25, its just a plug in and play repair (of course you could then get the fault code deleted on the ecu when its in for its next service).

Hi all,
Similar problem myself today. From what I am reading it sounds like my D3 has switched on limp home mode, with the errors "park brake fault auto release not available" & HDC errors. No mention of transmission faults though.
It's a 08 manual. The brake works fine manually still. Any thoughts? Feels software or sensor related, but I am no expert  ! Any ideas folks? Haven't checked fuse box yet. I do a little light offroading, engine could probably do with a clean, but knowing my luck it'll be something else wrong...!
Ironically, the warranty run out yesterday

| Brake Light Switch replacement link |
|
If the problem is the brake light switch, the link below to a few files that I have in my gallery covers replacement of the brake light switch - and as a previous post stated, it is fairly easy once you know where to look.
Also the replacement brake switch is I now presume an improved unit. Most early 3's have at some time in the past couple of years needed a new switch installed. As such, replacing the switch now even if it is still OK is rarely a waste of money. When you take the old one apart, you will probably see carbon dust from a failing contact.

No the cost will not be big time, but your investment in time going thru all the threads will be.
For the most part, the more fault codes and squawks you get, the less is wrong. The actual fix will be relatively easy, finding it will not be however.
Regard the various message systems and trouble lights as you would a baby crying. The vocabulary of the 3 is very limited. You as the parent have to figure out what all the noise means - is it something serious or just being a baby.
Per my previous post, my favourite fix for every problem on the 3 is a new brake light switch. First look and see if all the brake and tail light filaments are even working. Next, are the bulbs all genuine Land Rover supplied? You will not know so you may as well replace them all along with the switch.
