Hi all my 300 tdi disco has been stud for around 2 days and I've just come to start. It and the bat is dead and I mean dead, it's a new bosh battery as well. This has happened twice now.
My battery drain issue was down to the rectifier on the alternaotr keep sucking the juice out. A fully charged brand new battery would be dead in a few hours - all the way down to 3v. You could see it on a multimeter draining before your eyes.
