What's the noise in my Hyundai Sonata?

On my 2006 Hyundai Sonata CRDi I can hear a high pitched continuous bleep for about 10 seconds followed by a click from the engine just after switch off. This happens twice every time. What can it be?

Hi Greg,

That sounds to us like a relay that's on the way out. Pop the bonnet, get a friend to start and turn off the car and you should be able to pinpoint which relay it's coming from and replace it.
