I've got a 2000yr td5 Discovery that has developed a problem with starting. The motor had a couple of leaking sunroofs so was a bit damp inside.These have been sorted and with the good weather over last few weeks it has dried out . When I came to start it the starter motor came in on the 2nd ignition position instead of the 3rd. After looking at a wiring diagram I found the starter relay was getting an earth from the BCU as soon as the key was in the 2nd position,triggering the starter motor. I checked the BCU for water ingress but couldn't see anything obvious. I gave it a good clean with electrical contact cleaner anyway, but no change. I noticed my electric windows aren't working also but I'm not sure if this is related.
Can I fit a second hand BCU and programme it to my Discovery using my original keys ?
