"Optical parking system is not available at present"

[susheel]

HI
This is susheel, I bought a VW Jetta TDI recently. never faced an issue with my car but it had displayed a message stating that " Optical parking system is not available at present" and the Button haas started blinking for some reason. A loud beep is been released out when I put the gear lever in Reverse and the camera doesn't turn on either. I have no idea about this until now.
could someone please help me out or tell me whether it's a common thing in these vehicles.
Thank you .
