Sorry it's taken ages to reply - drive shaft went so had to replace that. But it's the two driver side ones that don't work. The passenger side made the noises. Where do I go from here? And costs?

Apologies if in wrong topic I have a 2004 Audi A3 2.0 Tdi dsg - my reversing sensors don't work. When I put it into reverse I hear a beep for about 1-2 seconds then nothing - what could be the problem?? Please bare in mind I don't have a mechanical mind so I don't know any mechanical words so please keep it simple if possible
