As VWUK don't allow us mere mortals to know what's been the subject of a TSB for our own cars; or even whether a TSB exists...

Here's the URL for the NHSTA site which will tell you what's been the subject of their interest and VWoA's own declarations
Search for a Service Bulletin | Safercar.gov | NHTSA

A listing of many N. American TSBs is also on the VW Vortex site, list and download server maintained by the site's moderator:
VWVortex.com - ****Official B6 TSB Thread - Every TSB .pdf is inside!**** (Links work)
When you get a TSB's link it may be necessary to close up the spaces in the URL. Been put there to avoid bots

While I'm down here here's the link for VWUK's recalls' search engine from your VRM or VIN:
