Driving the car yesterday and suddenly the alarm went off. Stopped and reset and it was fine. Then parked up UNLOCKED and off it went again. Left overnight with no problems. 3pm this afternoon having been sat locked all day the alarm triggered again. Now when I lock and unlock there is a distorted chirrup sound from under the front scuttle moulding. Assuming this is the siren but it's never done it before
any ideas guys???
