Hi everyone , I,m new to the forum I joined when I saw the same problem that I,m having posted on here, my 03 2.5 se also has the draining battery due to "rear passenger door open" alert keeping the interior light on. First thing I did was change the old ( 5 years ) battery but the problem persists so, not having the capability myself looks like a visit to an auto electrician to sort out the issue, just hope it,s not an expensive visit. Love Jags, this is my second after having a 2001 3.0 sport (in Liverpool red) for 8 years. Now saving for an F type ( I wish )
