Looking on citroen.service exploded diagrams, I'm told it's #11 part # 1338 78 but it also says it's "grey ring" (whereas the other two are correctly identifed as "blue" and "maroon") Could it mean green but lost in translation or something? If you say grey ring fast enough it does almost sound like green
But where's the pricing gone? When I go to basket all I get is a customer details form, no part number, no pricing.
So let's check the alternatives....
Looking on GSF online, they list one sensor for all Xantia's which is just plain wrong IMO. 929PC0150
