Newbi to Caddy Question - Ex BG Front Sensors?

[DaiCaddy]

Just picked up my EX BG 2016 Caddy, upon start up I get Front Park Assist not available, which after looking at front bumper there are no sensors, so this is obvs right, but should I either expect to have sensors as standard (A bumper change may have happened?) or can I retro fit with a loom and sensors, or code out if I get a VCDS? Thanks in advance, not sure i posted in right section earlier
