My battery goes flat on my 05 L322 Range Rover when the car in not in use for 4 or 5 days, We have changed the battery and the problem is still there. Charging is ok 14+ volts.
where can I start to look or has someone out there had a simular problem.

 

I had the same problem with a corvette, it tuned out to be the starter. I replaced it and my problem was gone.
