I have had my new 2.2 JTS all of 11 days now. It is fabulous in every way.
I decided to check if the alarm worked tonight. I sat in the car, armed it and waited, and waited... waved my arms about, nothing.
After some manual consultation I now realise that it is not supposed to give a second beep every time I arm it. Even so, the alarm sounds if you open either door or pop open the bonnet. I could find no problem with the boot lid and if it is left open the multifunction display lets me know. I do also get the 'alarm not available' message from the mfd on start up. If I try to disarm the volumetric, the led on the overhead button flashes.
Previous posts have mentioned a problem with the sensitivity of the master sensors in the doors. This was earlier in the year so you would hope that it would have been sorted by now.
I think my car was built in April (my airbag pyros need replacing in April 2020); incidentally, is there any way of knowing?
Is there anything else I could try, or does it have to go in? I was there only yesterday getting the drivers seat bolted to the floor (they forgot one!).
