What did you do to / for your E53 today??

Not sure if my little BT adapter drained it, but it was plugged in and flashing. The car hadn't moved since wed. Wife went out to go someplace and the door wouldn't even open.
Manually unlocked went in. Wouldn't even click. Just dead as a door post.
Read 12.3v at the engine bay tho. Hmmm

Told her to jump in the M3, right before she left, had her pull up and jump it. Very dead battery, had her sit a minute. Then tried again. It started. Christmas tree on the dash. Wow.

Sent her on the way and go on the interwebz and put an order in for a Bosch unit at PepBoys and had her go pick it up. Then started clearing codes while it idled. Could not clear a CAN error to the transfer case. Very weird.

I read 12.4v on the old unit. It was a bit swollen. Just a tad. Couldn't find the date on it.
The new battery. 12.3v. Hmmm. Anyway, swapped it out and it cranked right up. No lights on the dash. To include the tpms light that I've been unable to reset for the 2 years I've owned this damn 4.8
Covered over 50 miles and no lights have returned.
Dunno what that's all about, but I'll take it.
