Yesterday my 2007 Convertible began slamming when I put it into reverse. I've been told I need the valve body replaced. My research indicated an extension to the basic warranty of the 2003-2007 models to 100K Miles or 7 years. Both my local dealer and VW of America says my car is not covered because it is VIN specific. The dealer says a minimum of $1,900 to replace the valve body! Does anyone know if this is true or am I receiving the "run around." My car has only 63K miles on it!!!!
