I think it is the handbrake warning buzzer. Swith might have gone faulty

Have you got any display lights on dash? would either be low engine oil pressure or no charging from alternator. Obliviously could be faulty oil pressure switch itself or wire come off o.p switch / bad connection.etc. Put volt meter across battery, check charging when running, if only 12 to 12.5 Volt then no charging. also obvious check alternator belt in tacked & tight.Check alternator plug secure / connections clean. When you find which one it is, you might find bulb in dash warning light is gone. If charging light bulb is gone, it wont charge
