Erroneous bulb failure warning light & parking sensors no longer work

Hi, I hope you may be able to assist me with my 2010 Superb Elegance 2.0TDI (170) Estate 125,000 miles.

1. Dashboard is displaying an amber light bulb which i believe indicates a bulb is out.
2. Onboard computer is not showing any lights out when I check vehicle status.
3. A quick visual check of the lights (including reverse lights) has not identified any bulbs out.
4. Perhaps coincidentally, my parking sensors appear to have stopped working and just emit a long beep.
5. Parking sensor all appear to be in place and clean. 
6. Carly is not showing any light or parking sensor faults.

Any ideas what is going on?
