Alarm gremlin?

[grey42cerbie]

Guys,

After about 3 days not using the car (shame on me) I returned to find a very weak battery. There was enough power to open the doors. When I got in and started the car (really slow starter motor though) the alarm started going off. I could only reset it by stopping the car locking / unlocking it again. Any thoughts?

DAZ,

Thanks for the reply. The full story and hence the worried post, IS. When I went to look at the car the guy said he was having a new battery fitted as it had a dead cell? Sutton Coldfield OPC had the car in replaced the battery (i,ve got the receipt). They had it in for a few days to check that it wasn't draining, they said it wasn't. I'm guessing it is, so it looks like I'll have to book it in somewhere to get to the bottom of the problem.

The alarm thing is a pain it's not the 5-day close-down as that goes beep-beep-beep for 10 seconds before the alarm goes off. My problem is that the alarm goes off as soon as you start the car. The other stange thing is that it lets you drive off with the alarm going. Should it do this? I would have thought it would have an imobiliser as standard? Any further pointers welcome...

P.S. Got my first wave from a fellow Porcshe owner today, which was nice. What's the form here? do people generally acknowledge each other?

UPDATE...

Aparently there is some sort of problem with the offical Porsche batteries which causes them to fail if you run them down too low. I've just had a bigger capacity BOCSH fitted this will hopefully fix the problem.
