Ah, maybe I can see why there is confusion. VW changed the light in 2022 and again in 2023.
I guess it was originally 7C0 941 661A up to 06/06/2022 which then was replaced by 7C0 941 661B which was subsequently replaced by 7C0 941 661C at 15/05/2023 which according to the parts info that I can find is the only one now available and priced at about £100 plus VAT.
My best suggestion would be go to your VW dealer quoting your VIN and ask for the currently available part number. Then go back to MAN who should now be able to cross refer to their part numbering system.
By the way, VW car dealers should now be able to quote and supply commercial vehicle parts if they don't need coding to the vehicle.
Good luck.
