Hi Magnet, thanks for your reply!
I have just got back from the local dealership but the post-sales guy wouldn't give me the part number, just how much it costs unfortunately.
I have been looking online but there just doesn't seem to be anything that fits my layout of engine. Its an AWA, but going by the VIN, it's a slightly older spec'd one, and the parts just don't match.
I'll PM you my vin if that's something we can do on this forum, and in the mean time, I will continue to look around to find parts.
Thanks for your help!
