2015 Audi A5 FUEL/PROPULSION SYSTEM

CHECK ENGINE LIGHT CAME ON WHILE VEHICLE WAS IN MOTION ON AN INTERSTATE HIGHWAY. IT LATER WENT OFF WHILE DRIVING ON CITY STREETS. DEALER ADVISED THAT FUEL HOSE NEEDED REPLACEMENT AT COST OF $1,198. DEALER STATED THERE WAS A FLAW IN THE ORIGINAL HOSE AND THAT A REPLACEMENT KIT MUST BE INSTALLED. DEALER ADVISED THAT THIS IS A DANGEROUS SITUATION AND I SHOULD NOT DRIVE MY CAR HOME. DEALER STATED THAT THIS IS NOT COVERED UNDER WARRANTY AND THERE IS NO RECALL. I CALLED AUDI. THEY TOLD ME THE SAME THING AND SUGGESTED I CONTACT NHTSA. AUDI ISSUED A TECHNICAL SERVICE BULLETIN IN 2017 ADVISING DEALERS OF THIS PROBLEM AND INSTRUCTING THEM ON HOW TO INSTALL THE REDESIGNED REPLACEMENT KIT. INSTRUCTIONS COVER SEVERAL AUDI MODELS BUT DO NOT SPECIFY MODEL YEARS. TO RECAP, THIS SEEMS TO ME TO BE THE VERY DEFINITION OF NEED FOR A RECALL: 1.DEALER ADMITS THERE WAS A FLAW IN THE ORIGINAL DESIGN. 2. AUDI HAS REDESIGNED THE SYSTEM AND ISSUED INSTRUCTIONS FOR REPLACEMENT. 3. DEALER STATES IT IS DANGEROUS TO DRIVE THE CAR WITHOUT REPLACEMENT KIT. PLEASE ISSUE A RECALL FOR THIS DANGEROUS SITUATION.
