Alarm going off - 3 of last 4 days

[jpc763]

Hello,

I have a new problem. 3 out of the last 4 days at work, I have had people come and tell me that the alarm is going off on the Boxster. This has happened before, but like once or twice in the last 2 years.

Will a Durametric tell me what code caused the last alarm to go off?

Thanks, John

The alarm was going off at unexpected times.
It started in the winter when I was charging the battery.
The fronk was open.
A mouse had built a nest in the hood latching hole.
You might check for a mouse nest.
I now use electronic pest control.
I have not had any further issues.

So it has happened 3 times today!

Here is a screen grab of my alarm codes from June 2.



And here is a grab from just now.



The only code that has increased is code 33. Ideas as to what sensor that is?

Thanks. John

You have multiple faults, including the interior sensor (motion sensors above the mirror) and the radio sensor (a ground on the factory radio chassis).

Thanks Jeff. I have done some searching and found a thread on another forum where a sun shade was causing the interior sensor to go of. I bought one a few weeks ago and it was just before this started. So, I will be looking into that.

On the radio, I did replace the head unit and I thought I correctly reconnected the ground. Can you tell me what wire I need to make sure is grounded?

Thanks, John

This is one MAJOR thing that pisses me off about Porsche and Audi...too much CRAP is built into the computers... I MIGHT be more easy on them if they had TWO computers. One for strictly running the engine, and for for strictly running the things that women would care about.

There was a ground wire (brown in color) that was attached to the metal frame that the factory radio made contact with when it slid into place, that is the one you need to fix.
