An update for anyone finding themselves in the same situation.. The dealer was not happy to repair it under warranty as I'd already removed the unit and I smelled some serious charges in the works so I declined taking it in...
It wasn't possible to read the barcode to identify the type of drive as it was so buried deep in there but i got my digital camera in there and snagged the image in the end..

The barcode didn't identify if the model was the /p or the /f but I called the company and they set me straight which one was the pedal operated....
I only found the actual part available in two places, one was ebay and around $80+ the other was ordertree.com at around $56 plus $10 shipping so i got myself one ....
Here are the manuals and parts lists
