Boxster alarm keeps going off

Recommended Posts

1997 Boxster 2.5 Auto - right hand drive

I recently had a water leak inside the car which I have fixed

Trying to find it I played a hose onto the windscreen

The alarm got very wet

I locked the car and at 2 in the morning it kept going off

I removed it and put it in the garage

I have dried it out at home but when I fitted it today it just keeps going off

Will this re set or is it faulty

If I get another one is it 'plug and play' or do I need diagnostec equipment to re set it

Thanks Dave

The alarm got very wet

That is the key - do a search here you may or may not be able to cleanup and recover the alarm control box.

Durametric, a PST2, or PIWIS tester will help find the exact fault(s) -- but the key is if there is corrosion and damage inside the alarm control box.

If you did not open the alarm box and check for corrosion then you may well get an unwelcome surprise and get stranded somewhere when it fails.

When water gets inside operating electronics it can corrode connections and components. Many times the damage is not repairable.

Best find a shop that has one of the diagnostic tools I mentioned and see what fault codes come up.

If you end up having to replace the alarm control box you will need a shop with a Porsche PST2 or PIWIS tester. Re-programming the alarm control requires IPAS codes and all functional keys (along with their 40 digit unique id) to the car.

Sorry but this is not a simple task with the Porsche programming tool and the proper security codes.

It is the alarm in the front with the siren not the box under the seat

Can I fit a replacement by just pluging it in or do I need diagnostic equipment WHICH I DO NOT HAVE


So now please :-

The question is as above

If I get a second hand one is it plug and play

No I am talking about the alarm box under the seat.

Well I am not, please read my post correctly

The Siren -the red one -under the front hood - sealed and certainly very dry

it goes off on its own and does not stop even with the fob pressed, I have to take it off and wrap it in a blanket until it stops

Is it plug and play to replace it

Please do not be rude - I am trying to help you. My point is that if the alarm control box under the seat got wet - you likely have larger problems.

Of course the alarm siren can be replaced.
