My battery is toast. Replacing it today.

Anything special to replace one on one of these cars? I have a vague recollection there is something you should do but I might be hallucinating.

I don't know on those fancy newfangled cars but us poor old 996 owners need to have the radio code before unhooking the battery. However, maybe I'm just having a flashback...

Wait I thought I was talking to Zilla...nevermind

I have aftermarket radio so I don't need that. I thought there was something else. I guess I could look in the owners manual. It's all the way out in the garage though.

Send the kid out to get the manual.

I would walk out to get mine and check for you but it would be a long walk to Georgia.

I believe there is indeed something you are supposed to do to recalibrate a sensor or something, but I've never done that.

1) Insert new battery
2) Start car
3) Reset seat memory
4) Reset one-touch windows
5) Drive

I was hoping gnat would chime in as his car was five minutes from having a hole cut in the hood because of a dead battree recently.

Hmmm, I had the battery disconnected for a few hours while I did my radio thing and I don't recall doing any of that, other than resetting the radio. I think the seat memory is still stored. You'll definitely be disconnected shorter than I was if you're just replacing the battery.

You need to calibrate the window regulators and the sunroof - the limits have to be set. For the windows, just roll them up and leave the "up" button depressed for 5 extra seconds. This sets the upper limit for the regulator; until you do this, one-touch roll-up will not work (you'll have to keep the button pressed to roll the windows up).

The sunroof operation is similar - but one of the limit switches in mine is currently on the blink and I can't remember the procedure for setting the limits. Maybe someone else can...

Depending on which radio you have, you'll need to re-enter the unlock code each time the battery is disconnected (what a pain). This was the case with the MOST-bus system in my '03 986; my '99 Carrera 4 does not need a radio code each time.

If you have a C4 and less than half a tank of gas, disconnecting the battery will cause the car to lose the estimated distance until empty value, and the gauge will not be accurate until you refill the tank.
