The Ford ordering system does not list parts that are not considered as options (even if they would fit) so my local dealers were unable to order the part for me even though I gave them the Ford part number.
I am now sorted and ready for the winter ice, well as ready as possible in a Fiesta

Thanks to all those who have contributed to this thread - lets hope it helps others.
I had this trouble when seeking a fitting kit for the engine cover on my 1.6TDCI, ford didnít have the parts I required listed as available items for my model as it was not standard,
so they went out to the sales yard and acquired a chassis number from a model that had the parts fitted,
then entered that chassis number in to the system and could sell me the parts i needed then, may save people trouble shooting different dealers.
