not sure. think somebody on here said they were updating the site or something.
www.vagparts.com is another one to use. if you register and then send them a mail to say your are a member of this forum you'll qualify for a discount. I think it may be 15%, but somebody else can confirm this.
Think I remember reading a while ago that they had "pulled" the site for a while due to other commitments but were planning to come back online when they had more time.
