Hi, have just got myself a disco 2 and all of a sudden have a problem with the central locking. When you lock with the fob all doors lock except drivers side rear door, and horn beeps once. After manually locking the door unlocking with fob results in all doors opening except the rear drivers side. If you use the key it also refuses to work. Any ideas as your help will be welcome.

Hi just had a very similar problem with the back door what a pig.
Top and button of it is you cannot do a lot with it apart from getting a new lock I have got around this for now by cutting the cable to pin 5.
My one was on the back door and it thinking the door was open stops the air suspension from working.
Cutting the wire will let it lock stop it from bleeping at you BUT the alarm will not go off if the go in that door then just look for a second hand lock.
I opened the look in the end it is just a small micro switch nothing you can do with It price from landrover for new back door lock was £63:00 not good got one from the scrappy £4:00 job dun

Cheers for that, I'll give it a go. Good job this site is here, asked around in Jersey but everybody seems to drive cayenne's. To***rs.
