Reported cause
Mine was caused by lack of use which then somehow also resulted in the alternator packing up - after covering 12K miles!!!
Leading evidence: 'lack of use' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'lack of use' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Recommend anything other than a porsche one' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

In which case I would recommend anything other than a Porsche one.

Suggestion
I'm led to believe that it might be possible to replace just one of the (solenoids?) on the alternator as opposed to the whole thing - you'll have to check this though.

Forgot to mention that the reason your alarm was going off was because your battery had run so flat that it had the same effect as someone removing the battery from the car.

The main battery keeps the slave battery consistently charged up so that it'll run the tracker and alarm for a short while if the battery fails.

I would initially get the battery tested by your local auto electrical specialist to see if one of the cells has collapsed (as mine had) and also get him to check the output of the alternator - if you can get the car to him.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi, woken last night at 2:30 by alarm going off, unable to reset using fob went down opened car noticed windows wouldn't drop, spolier had raised ?! tried to start car battery flat.
I assume the alarm was triggered by the voltage drop
Have now removed battery and its at 9 volts - not enough to crank car
So from what I can work out something since Sunday when I went on a 200 mile round trip has been draining the battery, no lights were left on,
anyone got any ideas what could cause this?
Only strange thing I noticed on my trip on Sunday the radio wasn't working - the word Porsche showed across the matrix very faintly but the unit couldn't be turned on or off - I am wondering if when I left the car Sunday night if it was still in this mode (showing the word Porsche across the matrix faintly) and drawing current - anyone seen this before its a CDR-22?
Previous to Sunday the radio had worked fine, its a CDR-22 controling a 6 disc autochanger and the bose speaker system - seperate amp in the boot - could it be the switching through the amp that is faulty I guess the 2 are connected (when the head unit is switched on the amp is too.?.
Cheers
Hi. Sorry to hear about your problems - I've had exactly the same problem in the past on my MY 2003 996. The window and tail spoiler behaviour are all symptomatic of a knackered battery. Mine was caused by lack of use which then somehow also resulted in the alternator packing up - after covering 12K miles!!! :?
I would initially get the battery tested by your local auto electrical specialist to see if one of the cells has collapsed (as mine had) and also get him to check the output of the alternator - if you can get the car to him. I'm led to believe that it might be possible to replace just one of the (solenoids?) on the alternator as opposed to the whole thing - you'll have to check this though.
I ended up getting a new alternator from my indi for around £250 (fitted, which is a pig of a job) - which was about £200
less
than my OCP had quoted me for exactly the same alternator.
If your alternator tests good then all you'll need to do is get a new battery. In which case I would recommend anything other than a Porsche one. The Bosch Silver's are good and you can sometimes get them at discounted prices from Costco.
One thing I would beware of though: do try to get you alternator tested
before
you splash out for a nice new battery as it'll get drained pretty damn quickly - even when the car is at rest!
Hope this helps - and hope it's just your battery!
Adrian.
....Sorry. Forgot to mention that the reason your alarm was going off was because your battery had run so flat that it had the same effect as someone removing the battery from the car.
This is a safety feature of the car which prevents someone just quickly removing the battery to stop the alarm going off if they're trying to steal the car. The alarm that you heard was being powered by a small 'slave' battery that sits next to your main battery. The main battery keeps the slave battery consistently charged up so that it'll run the tracker and alarm for a short while if the battery fails.
Thanks for the reply re: the flat battery - anyone had the CDR-22 pack up in this manner.
Dot matrix has the word porsche written across it faintly illuminated and unable to turn the unit on or off.
