911 996 Carrera 4 1999.
The car doesn't get used all the time, and sits on a driveway. There seems to be a problem holding the battery charge. If the car isn't used for a week, the battery goes flat, causing the alarm to go off, and I haven't found a way to stop that - usually it stops by itself after a while, but I've had to get up in the middle of the night to fiddle about with it until it stops. I can re-charge the battery in an evening, and the car will start OK afterwards, and will continue to be OK as long as I use it every day. Both battery and alternator are only around 18 months old. The car has been checked over by a garage that specialises in Porsche, and they have found nothing wrong with the charging, and no evidence of untoward battery drainage.
Does anyone have any ideas, please?
Many thanks
Ed
