I took my car upto my dads factory yesterday so I could do some work on it. I left the ignition on so I could listen to the radio, but I left it on the second click, where all the dash lights up. After a while a long drawn beep sound starting coming from the engine bay. Pushed all connectors I could see to make sure none had come loose somehow and still kept hearing it. Tried to start the car, the engine turned but it didnt fire up, it just stopped suddenly and I cant get this siren sound to stop. Its been beeping since yesterday and its still doing it now. Any ideas what it could be?
