@Kezo seems a common thing across the PSA group Citroën has done it on the C4.
Some C3 Aircross Shine Plus has come without Parking Sensors.
Peugeot seemed to have started before Citroen even as the electric tailgate on the 3008 and 5008 top spec models came a common topic being missing or becoming cost options.
The C4 Shine Plus lost as standard Leather Heated Seats, Wireless Charging and Subwoofer now all cost options. But the AP of the same car has risen though.
