Rear glass windshield started to come apart n rain water leaked in n short circuited the wiring . the window finally came apart completely n fell off. becaus of the water leak , it short circuited the wiring n the comunication with the main computer is corrupted n the air bag sign is on also. this is a big fire hazard n i have to reinstall new wiring n hv a new roof install. this rear window problems are on all audi convertables because of the bad glue. its high time that a recall on this should be issued as this is also a major fire hazard also as well as a safety issue.my car has only 25,000 miles on it now.
