Since the time I bought my 2005 LR3, I cannot leave the car unused for more than 2-3 days without the battery draining completely. I thought I had it finally figured out when I brought the car in for service.
I originally had the factory-installed Rosen A9 DVD player. Then one day while in the garage, I accidentally bumped the car lightly with my hip and then heard a short "tock" sound, which sounded like the car leveling itself as it normally does when parked over a period of time as the air in the suspension slowly bleeds. Immediately, I noticed a red flashing light in the left DVD dome light. This light comes from a numerical LED inside the dome light that lights up as the DVD goes through a boot-up process only after power has been completely disconnected from it, such as when the DVD fuse is removed and then reinstalled. I then noticed the lights on the DVD buttons turn on and remain on for 15 minutes. While monitoring it intermittently during the rest of the evening, the DVD button lights would come on randomly about every hour and remain on for 15 minutes.
LR's solution was to replace the DVD player with the Rosen G10. But that didn't work because the car would not start again after 2-3 days of unuse. I noticed the same syptoms again as the orginal DVD player when I inadvertently touched the car as I lightly pushed down on a moulding on the windshield.
Here's what I know so far:
1. The "tock" sound is always a precursor to the DVD light buttons coming on. I believe this comes randomly over time as the car levels itself while parked. After a period of time of inactivity, I think the leveling process can be prematurely triggered by slight nudges of the car.
2. The DVD light buttons stay on for about 15 minutes at a time. It may come on again in about an hour or so.
I am going to send the car back in for this same problem, but I would rather come in with suggestions than them experimenting with the car. Has anyone else had the same problem or symptoms?
