2004 AUDI S4 CONVERTIBLE - 40K - REAR WINDOW OF CONVERTIBLE TOP HAS SEPARATED FROM TOP - APPEARS TO BE GLUE, ATTACHMENT METHOD FAILURE. CALLED AUDI OF AMERICA REQUESTING ASSISTANCE, V. NICE - WANTED TO INITIATE CONVERSATION / INSPECTION 'AT DEALER LEVEL'. LOCAL DEALER LOOKS AT IT AND QUOTE $4350 TO REPLACE ENTIRE ROOF. DISCUSSIONS BETWEEN AUDI OF AMERICA AND DEALER APPARENTLY ENSURE WHERE 'LEVEL OF PARTICIPATION' TO ASSIST IS DISCUSSED. WE HAD PREVIOUSLY PURCHASED A NEW S4 AT THIS DEALER IN 2000 AND TRIED TO PURCHASE S4 CONVERTIBLE FROM THEM IN 2007. WE HAD OWNED 10 (TEN) VWS PRIOR. FURTHER, ASST SVC MGR AT AUDI OF TYSONS CORNER ADVISED THAT I SHOULD HAVE GARAGED MY VEHICLE, PROBLEM WOULD NOT BE FAILURE OF ADHERING PROPERTY, BUT CLEARLY NOT MAINTAINED PROPERLY BY ME. MY REQUEST FOR ASSISTANCE WAS REFUSED BY THE DEALER BECAUSE OF 'DEALER LOYALTY'. AUDI OF AMERICA SAID THEY COULD NOT OFFER ANY HELP EITHER. I SEE ON THIS SITE THAT MANY HAVE HAD THIS PROBLEMS WITH 03 CONVERTIBLE PRODUCTS AND PRIOR TO READING THOUGHT THAT THIS ISSUE IS SOMEWHAT IF NOT ENTIRELY THE RESPONSIBILITY OF AUDI - AFTER ALL - SHOULD WE ANTICIPATE REPLACING AN ENTIRE ROOF FOR ALMOST $5000 AT ONLY SIX YEARS ???? AS A HUMOROUS ENDNOTE - THE DEALER CALLED ME TODAY - WE HAD LOOKED AT CARS WHILE THERE - THEY WANT ME TO COME BY - TEST DRIVE AND BUY :-) *TR
