Battery Drain
My 2006 750li has a serious battery drain .I bought a new battery, dead in five hours. I am also receiving a transmission error message.Do you think the problem is the alternator?

Transmission Failsafe on my 2004 745i and all kinds of codes a few months after replacing the battery and registering it ended up being the alternator. I replaced the alternator with a 180amp Valeo and the car runs perfect now.

Thanks, I didn't program the battery either.
