Yeah i've given them the chassis number and alsorts.
town325i - that must be why they've been giving me the wrong gasket in the past
I've just spoken to JCT600 BMW and they wouldn't order the part in for me unless i went down and pre-paid for it in cash (before they'd place the order)!! They wouldn't even take payment over then phone which seams alittle odd!
So instead of wasting 2hrs driving there and back I've managed to source the lower sum gasket from here:
http://www.gsfcarparts.com/ who were more then helpful, and asked which gasket (upper or lower) that i required... which none of the others did.
Will have to see if its the correct one when i go to pick it up.
