I just tried to order a filter oil pump for a mexican 1600 beetle through a local VW dealer in Orlando. I had part numbers and all. He tells me he is really sorry, my part numbers are valid and all, but VWoA will not ALLOW him to order the parts for me and no dealership will have them in the US, because the mexican made beetles were never imported into USA. So.. the parts are available and everyone knows where and whan numbers, but the corporate will not LET us get them. That's customer service! He suggested I call directly to a dealership in Mexico and order them from there.
I'm waiting for a reply from Aircooled.net where I see something like that listed on the site :D
