If your VW dealer chooses to play dumb, phone the zone rep for VWOA, to see if you can get the appropriate attention at that level. If not, go to your state's Division of Consumer Protection to see if you can get action there. If not, go to the National Highway Traffic Safety Administration (NHTSA) website at www.nhtsa.gov
(I believe) and file your concern. I filed with NHTSA once, and was able to force a recall of '93 Taurus/Sable cars in the upper midwest (road salt corrosion pitting of front coil springs leading to spring breakage). You have a SERIOUS safety issue here, and you should NOT let the dealer or VWOA stonewall this!
