2002 C2 intermittent alarm issues - need help

[p0rsch3]

My alarm occasionally goes off for no reason. I'm thinking it is a faulty sensor in the door, engine compartment or front.

I've ruled out the interior sensor by arming it with the sensor disabled.

My girlfriend says it goes off occasionally because my pcar misses me and wants attention.. LOL

The false alarms usually occurr early morning or late evening when the outside temperature changes.

Does the sensor record an event in the computer when it is tripped? If so, I might be able to have the computer readout let me know which sensor was triggered so I can replace it?

The Porsche dealer is absolutely no help. They just want to replace the entire brain (expensive) and hope it fixes things.

This is driving me nuts because there is no way to lock the car without enabling the alarm.

Yes, if you read the alarm fault codes with the Durametric Software, a PST2, or PIWIS tester.

It will likely tell you where the alarm faults are.

Thanks Loren-

Actually, with a PST2 or PIWIS you can test each individual alarm sensor in the car.
