C32 did not Start (No electrical power)
This is the 2nd time in the last 3 months I have tried to start the car and no electrical current available.
The first time, I jumped the car battery and unplugged my drivers side seat module and everything was ok. I knew it was the seat problem.
This time the car sat in the garage for 3 days and it would not start. I jumped the car battery and unplugged the passenger seat module. But I'm not sure if that is causing the problem.
Anybody has a guess what else can be drawing current from the battery?
I'm driving with a car that can move the front seats unless I plug in the seat modules. I just love all the electrical issues with this car.

From is my experience, unplugging the seat modules was not sufficient. My car will literally die every morning.
The symptons:
1) Nav CD kept spinning even when the car turned off.
2) Seats were not in the correct position when entering the car after a while.
3) A bunch of electrical malfunctions after each jumped start. The rear sam blew up by jumped starting the car too many times.
I ended up replacing both seat modules, the rear sam and a new battery to fix the problem. It's been over a year and no problem so far.
Good luck.

Did you change ur alternator recently? Did you get any alternator error msgs on ur display? Mine just went out all of a sudden on the same day it started complaining about the alternator, the car completely lost power!! I had to tow it on a flat bed after dinner on a Saturday night to the dealership!! They replaced the alternator which seemed to put power back to the car! I also have the seats unplugged but I probably put a lot of stress on the alternator in the past from the multiple times I had to jump-start the car before I figured it was the seats causing the battery drain. You might have a fried alternator if you had to do multiple jump-starts to the your car in the past as well!

I've had both seat modules go within 3 months of each other, now I just drive around with them unplugged, symptoms were similar but it's fine now (as long as I don't need to move the seats!)

The rear SAM is basically the fuse box in the trunk. PN: 203-545-34-01.
I had to replace it because I jumped started the car too many times.
If you change the battery w/o fixing the problem, the car will be fine for 2-3 weeks max. Then the problem will come back. I would start by replacing the seat control module that has the current draw.
