Would anyone know if headlights from a 1996 UrS6 are replaceable by those from other models? FA says only 95-96 A6/S6 is compatible. We are looking at a possible buy of a car with a cracked headlight, replacement would be needed as temporary fix to pass safety inspection, proper headlights to be installed later. Thanks.
