Reviving the car after a dead battery
On Sunday I came out to find a fully discharged battery (the headlights were left on), so I pluged it into my battery maintainer for a few hours and the car started right up. In the manual it indicated that the PSM should clear itself, which it did. The PSAM however is not working. The SPORT mode will activate, but the PSAM will not. Any suggestions on how to clear this fault short of scheduling a dealer service.
Thanks,
JFS

If you have a dead battery you have to jump the front hood to get it to open. You do that by hooking jumper cables to the fuse box. It's covered in the Manual and easier than one would think.

My battery was dead this morning after not driving the car for about 40 days. Used the pull out red terminal method to open the hood and charged the battery overnight. Started up the car and had PSM and PASM failure and the sport mode will not activate either. I'll take it for a drive later and see if anything resets. Hope I don't have to make a 3 hour round trip drive to the nearest dealer to have everything reset. Anyone using the more common battery maintainers that are available instead of the Porsche branded ones?

what's the deal here - this car can't sustain a dead battery without having a dealer visit to reset the ECU?

It is very easy to use and will end your dead battery. I used it frequently on my 993 which sat often.

It's just a friggin trickle charger, folks. The Sears Diehard name has a solid reputation in battery products. Never knew Porsche to be in the battery business. Ticks me off that Porsche must think that people are stupid and blinded by their name that they are willing to fork over twice what a product is really worth. I wouldn't be surprised if the same OEM that makes them for Sears makes them for Porsche.

I bought a Sears Diehard battery maintainer that sells for $29.99 and that's what I currenly use to keep my battery charged while my car is in storage. It's every bit as good if not better than the Porsche branded charger. It's got the cigarette lighter adapter and three indicator lights to let you know charging status.

Started the car yesterday morning after charging it overnight. The PASM failure cleared itself before I could back out the garage and the PSM cleared up after driving out the driveway. What's really funny is when I started the car the night before and got the failures (didn't drive it) the stereo and clock appeared to have lost station memories and time, but after charging overnight everything was back to normal.
I asked about other brands of battery tenders because I have one left over from my motorcycle days and didn't feel like buying a new one if I didn't have to.

where is the Sears product made, versus the Porsche product.
If its made in china, its junk - all their electronics are junk.

walmart sells a "Black & Decker" for under $20, comes with 3 options, cigar lighter adaptor, clips & hardwire to battery, 1 or 2 watt charge and a polarity lite. I have 3 and they work fine
