Turns out (from a trusted source) that Pierburg don't yet sell it into the aftermarket for my particular application as its under license to Ford until 23rd December 2016.
When questioned about it as the part appears faulty (another story) they weren't sure what has been supplied as it came via ECP.
AP rep came out today and thought it was OE by the part number so he checked with there source for OE parts, sure enough its not yet listed and they can't supply.
The truth is and I quote "we haven't a clue what make it is and where it came from" so read imto this as you want.
sorry for the long post.
