I have for some time had a loud clunking sound when my sliding door
closes. Turns out there is a special "stop" this is supposed to be
inserted at the end of the door travel at the point when the mechanism
cams over to suck in tight to the body. It absorbs the impact of the
door sliding forward just before closure. If this part is missing, the
roller in the door, and the metal at the end of the track will be
damaged. I finally got around to ordering the part - less than $5.00
from Camelback VW in Phoenix, AZ.

The part can be seen on ETKA in Illustration 107-00. Item POS 10,  Part
Number 251 843 876  It's called a "Stop".

I would suggest that all owners of our beloved vans check this stop. Be
sure it's there. Not a biggy, easily seen. If it is missing there will
be a horizontal slot with nothing in it. Without the stop, the metal at
that point gets hammered!!
