Found my trunk light has apparently been staying on and draining my battery for the last 6-8 weeks. I've had to recharge the battery every 4-6 days. I shoud have known that the snow free spot on my trunk was NOT a lock heater but the trunk light.Can anyone tell me where the switch is? It's 0 degrees outside and I took the bulb out so there is no real hurry on my part to fix it. Thank Jens Joe C 86 735i 85 524td
