Find a new dealership. That's probably easier said than done, of course...
This part is a common weakness, and if the dealer had any clue what-so-ever, they would have known immediately what you wanted, and probably had a handful in stock. I've replaced mine once already, and I suspect there's a pretty large percentage of owners who have.
Use the info that Y33TREKker left you above, and call Merlin. Your dealer is useless.![]()
