Here is online version of ETKA, the VW parts catalogue.
This one is free to use once you register (excuse the pun) and is fully searchable by date of vehicle. Its an Eastern European version though, so a disclaimer is best expressed here, but in terms of printing it out, identifying part numbers and suchlike to take to your VW dealer, its quite useful.
I also find this one useful when determining such things as what odd little vacum pipe fits where and where does that widget go…
