I feel your pain...

but saying that, went in for a new fuel cap (the plastic part around the barrel and walked away with one. Altough its the same as a normal mk5 too, still shocked me that they had it...

but as far as i know, they are not, but no harm in trying though, they might just be able to order them for you, which you might wait a week or a month, but this way you get the proper ford reciept for your history.
