Left or right hand drive?
LHD p/n is 191 819 415C
RHD p/n is 192 819 415C
VW have redesigned this part, it is now a lot thicker and stronger, and both LHD & RHD are still available from the dealer, but as they cost somewhere about 35 euros (25 pounds) a piece though, this might explain why they are still on stock,
btw, the 2WD part is the same so a visit to your local scrapyard may pay off.
