Horn double beep

[donkeydee]

Hi

I am new to the forum but have a problem with my 996 cabriolet. When I lock the car with the fob it makes a noise like its trying to lock but unlocks, but then the second time it locks properly but the horn beeps twice. It also beeps twice when unlocking. I know that it will probably be a micro switch but is there any way of narrowing it down.

One beep means an alarm zone is open.

Twp beeps means there is an alarm fault.

Without a diagnostic tool to read the alarm fault(s) everything is just an (expensive) guessing game.

You need to get the car read with a Porsche specific diagnostic tool (i.e. Durametric, higher end Autel scanners, or Porsche PIWIS).

I have an Autel Scanner that will read all the modules on my Porsche 996. Works great with my Volvos too. Without a doubt it has paid for itself. I was having the same frustrating double horn honk too. Replaced a faulty microswitch on the front lid (i.e. frunk) and it fixed the problem. The scanner will help point you to the source of the problem if you can't find the culprit by using common sense observation.

Thanks for the info. What model Autel do you use.

I bought mine three years ago and Autel has since discontinued it. But it's the MD702. I paid a couple hundred for it which I thought was a good deal. Their pro systems exceed $1000. Just make sure you buy one that will read all of the modules on your Porsche 996.

Check the Frunk, trunk, glove box and center arm rest......do the lights in the frunk or trunk stay on ???
