Horn beeps twice

[boxtoff]

I'm having the same problem, and only had a similar issue fixed last week... back to the dealership me thinks. According to the manual if it beeps twice it is an issue with the alarm / central locking system. It was doing it last week and that was down to a faulty sensor, which I'm guessing wasn't fixed correctly.

You need a PST-2 or a trip to the dealer to read the alarm system's event and error logs. It will tell you which one of the many sensors are at fault.

In your case, take it back to the shop and insist they fix it for free.
