No battery drain or removal, but TL still resets memory seats and radio!?
 

Hey everyone, I'm hoping someone can shed some light on an issue I discovered yesterday with my 07 WDP TL.

I started up the car yesterday and noticed that the seat was not returning to the position I had set for it. My wife had taken the car earlier to her sister's house so I thought I'd ask her if the battery had drained or if the car didn't start in the morning. She said no, and that everything was fine. Yet, the car still asked for my radio code, for navi and the radio.

I have just replaced the battery with a Interstate about a month ago, it has 800 CCA, so I doubt it was the battery. It has been cold here for the past little while, just hovering around 0-9 degrees Celsius at night - could this have something to do with it?

If anyone has any info or insight that would be greatly appreciated, hopefully this is just some phantom occurrence and doesn't happen again.

1) Check the clamps and make sure they are tight, esp. the negative clamp, and can't be moved by hand. Tighten if loose.
2) Check for corrosion on the clamps and under the cable sheathing. Clean off any found.
3) Check the ground and starter ends of the cables to make sure they are on tightly and cannot be moved by hand. Tighten anything that is loose.
4) Put a meter on the HFL 35+ minutes after turning off the car to see if there is an excessive draw (don't do this within 30 minutes of turning off the ignition-- the HFL is supposed to stay on for 30 minutes afterwards).

Thanks for your reply. My hands free link has been disconnected for quite awhile now, so it's not that. I will check my connections and see if they are clear and tight.
