Warwick Duo Plastic Cover behind battery

Hello all
I have broken the plastic ventilated cover that hooks onto the bottom of the seat of my Warwick Duo 2013.Can anyone tell me what it is called and where I can get a new one? Inside it says PP-TD20 and C539.I have searched the forum without success.

Similar problem with my Sussex Dou. The attachment lugs have broken, but manager to secure with a couple of self tapping screws. However the broken one was on the passenger seat, easy to fix, but may be a difficult on the back of the drivers seat.

The part is standard Peugeot, not from A-S. So your route is to ask your local friendly Peugeot dealer for the part number and a price (be prepared to be horrified)
