Battery Drain Issue 2011 RR L322

[Amund Thompson]

1.5A draw killing battery overnight, checked and pulled all fuses one at a time (both in cabin and engine bay), no drop found (meter in series). Any ideas?? Alternator diode?

Wow thats a tough one you did what I would of done. But these days its hard to find something thats a draw, could it be just a battery?

I can't remember where, but I recently saw a post somewhere detailing this exact issue, and it is caused by turning the ignition off when:

1. The navigation system is active
2. A phone is connected via Bluetooth

I believe there is a software update that fixes it.
