   RE: SAFETY RECALL 20L8/JY; 08V157000: FUEL TANK ROLLOVER VALVE MODIFICATION; VIN: (XX); 2004 AUDI A6 3.0L QUATTRO AT5 ATTACHED DOCS: 1. 20L8/JY RECALL NOTICE. 2. 7.14.2008 & 11.18.18 AUDI N. SCOTTSDALE, AZ DEALER INVOICES 3. AUDI A6 GAS TANK DIAGRAM. AUDI CORP EMAIL RESPONSE: "AT THIS TIME WE HAVE IDENTIFIED THAT THE 20L8 REPAIR WAS SPECIFIC TO THE DRIVER'S SIDE OF THE VEHICLE. THE DEALERSHIP IS INDICATING THIS CURRENT RECOMMENDED REPAIR IS SPECIFIC TO THE PASSENGER SIDE OF THE VEHICLE." "SINCE WE ARE SHOWING THE 20L8 COMPLETED IN JULY OF 2008 AND THE ORIGINAL 20L8 REPAIR IS SPECIFIC TO DRIVER'S SIDE ROLLOVER NIPPLE VALVES, ACCORDING TO THE DEALERSHIP THIS CURRENT REPAIR IS UNRELATED TO THE RECALL." "CURRENTLY PER THE NHTSA WEBSITE, THE 20L8 IS NOT SHOWING AS AN OPEN RECALL, SO I WOULD BE UNABLE TO SPEAK TO HOW THEY WOULD REACT TO INFORMATION REGARDING A CLOSED RECALL." 'WE HAVE NO EVIDENCE SUPPORTING AN INCORRECT REPAIR BEING PERFORMED IN JULY OF 2008, SO AT THIS TIME WE WOULD BE UNABLE TO PROVIDE ASSISTANCE TOWARDS THIS REPAIR." CURRENT EMISSIONS CHECK ENGINE LIGHT (NOV 18, 2018) IS DIAGNOSED BY THE AUDI DEALER AS A GAS TANK LEAK. ALSO, THERE IS A STRONG ODOR COMING FROM GAS TANK. DEALER QUOTED TO REPLACE THE ENTIRE TANK (SEE ATTACHED #2). THERE ARE SEVERAL ROLLOVER VALVES ON EACH SIDE OF THE GAS TANK ON THE TOP SIDE (SEE ATTACHED #3 GAS TANK DIAGRAM). RECALL (SEE ATTACHED #1) DOES NOT ADDRESS "DRIVERS SIDE OR PASSENGER SIDE" OF GAS TANK. DEALER CLAIMED THAT BACK IN 2008 THAT THEY DID NOT EVEN LOWER THE GAS TANK FOR THE REPAIR. IN SUMMARY: MY VEHICLE CURRENTLY HAS A GAS TANK LEAK ON TOP OF THE GAS TANK COMING FROM THE ONE OR MORE ROLLOVER VALVE NIPPLES ON TOP OF THE GAS TANK. THE SAFETY RECALL ADDRESSES REPAIRING AND REINFORCING THESE LEAKING ROLLOVER VALVE NIPPLES SO A REPAIR REQUEST SHOULD BE COVERED BY THE RECALL.

   AFTERMARKET RADIO: PIONEER ELECTRONICS AVH-4100 NEX BACKUP CAMERA FAILS AND DISTRACTS DRIVER SIGNIFICANTLY. I HAVE ATTACHED A SCAN OF THE COMPLAINT TO PIONEER ELECTRONICS. THE RADIO LIKELY HAS SOFTWARE DEFECT THAT CAUSES VERY DISTRACTING FAILURES WHEN OPERATING THE BACK-UP CAMERA. PIONEER ADVERTISES THAT THIS BACKUP CAMERA WORKS AS ADVERTISED - IT IS ACTUALLY NOW A DISTRACTION AND HAZARD. AS WELL, OPERATING GOOGLE "ANDROID AUTO" CAUSES MORE SIGNIFICANT DRIVING DISTRACTIONS WHEN USING THE BACKUP CAMERA FUNCTION OF THE AVH-4100. COMPLAINTS TO PIONEER ELECTRONICS HAVE BEEN FRUITLESS. THEY SEEM TO BE ARROGANT AND CLAIM: "ALL OF OUR PRODUCTS ARE THOROUGHLY TESTED." I WOULD LIKE PIONEER ELECTRONICS TO FIX THE SOFTWARE ISSUE AND CREATE A NEW RELEASE THAT ALLOWS THE BACKUP CAMERA TO WORK WITHOUT A DISTRACTION AND SAFTY-HAZARD.

    I AM WRITING ABOUT MY 2004 A6 AVANT, WHICH HAS 78,000 MILES. AT A RECENT OIL SERVICE AT AN INDEPENDENT GARAGE, IT WAS SUGGESTED THAT THERE WAS A PROBLEM WITH THE CATALYTIC CONVERTERS. EXHAUST WAS LEAKING FROM BOTH SIDES, I WAS TOLD. I TOOK THE CAR TO MY AUDI DEALER, WHERE THEY CHECKED THE EXHAUST SYSTEM. THE MECHANIC WHO EXAMINED THE CAR CONCURRED THAT THE CATALYTIC CONVERTERS NEEDED TO BE REPLACED. UNDER A FEDERALLY MANDATED WARRANTY, THE CATALYTIC CONVERTERS ARE COVERED FOR EIGHT YEARS OR 80,000 MILES. YET THE DEALER HAS DECLINED TO COVER REPLACEMENT BECAUSE THE "CHECK ENGINE" LIGHT WAS NOT ON. I WAS GIVEN A REPAIR ESTIMATE OF $2,400. *TR

    I FILED A COMPLAINT ABOUT MY 2004 AUDI A6 IN DEC OF 2009. I REPORTED THAT MY BACK PASSENGER SEAT HAD ALMOST CAUGHT FIRE, AND WAS BURNT. BOTH MY SEAT CUSHION AND UPPER BACK CUSHION WERE BURNED. AT THE TIME I HAD NOT CONTACTED AUDI, YET FILED A COMPLAINT, BECAUSE I FELT AND STILL DO THAT THIS WAS A MAJOR SAFETY HAZARD. SINCE MY LAST COMPLAINT I DID CONTACT BOTH MY DEALERSHIP (ROTH AUDI IN ERIE, PA) AND AUDI HEADQUARTERS AKA: AUDI CUSTOMER RELATIONS. THEY WERE VERY WILLING TO WORK WITH ME, SEEMED EXTREMELY CONCERNED AND SAID NOT TO WORRY BECAUSE I STILL HAD A WARRANTY LEFT ON MY CAR. WELL AFTER THE CAR RETURNED HOME FROM THE DEALERSHIP THEY ONLY FIXED HALF OF THE PROBLEM! THE DEALERSHIP SAID AUDI TOLD THEM TO REPLACE THE BOTTOM CUSHION ONLY. THE DEALERSHIP PAINTED OVER THE TOP CUSHION AND I FOUND THIS OUT AFTER I BEGAN WIPING MY SEAT, BECAUSE I THOUGHT I HAD SMUDGE MARKS ON IT... NOPE PAINT WAS COMING OFF AND COULD SEE THE BURNED SEAT UNDERNEATH THE PAINT. I CALLED AUDI BACK, AND THEY HAD ME TAKE IT BACK TO THE DEALER TO BE ASSESSED AGAIN. AFTER 6 DAYS OR SO THE PERSON I HAD BEEN DEALING WITH FROM AUDI CUSTOMER RELATIONS CALLED TO SAY WE CANT REPLACE THAT PART OF THE SEAT BECAUSE THEY FOUND NO DEFECT IN THE HEATING ELEMENT. SO IN ESSENCE, THEY ONLY DID HALF OF THEIR JOB SINCE THE SEAT BURNED FROM ONE INCIDENT! I HAVE SINCE CONTACTED THE FTC, AND THE ATTORNEY GENERAL RE: THIS ISSUE. I WILL NOT STOP THERE IF I DO NOT GET THIS RESOLVED. THE ENTIRE SEAT SHOULD HAVE BEEN COVERED UNDER THE WARRANTY. CONSIDERING VW RECALLED MANY OF THEIR CARS FOR THE SAME REASON, AND AUDI IS OWNED BY VW I WOULD THINK THEY WOULD BE A BIT MORE CONCERNED ABOUT THEIR CUSTOMERS. I HAVE VIEWED MANY FORUMS, AND FOUND THERE WERE A LOT OF COMPLAINTS SIMILAR TO MINE WITH REGARDS TO THE HEATED SEATING EITHER CATCHING ON FIRE OF BURNING THE SEAT. I'D LIKE TO KNOW IF NHTSA IS HONESTLY LOOKING INTO THIS? THANK YOU. *TR

    TL* THE CONTACT OWNS A 2004 AUDI A6. THE CONTACT STATED WHEN THE VEHICLE IS PARKED THE THROTTLE FLUCTUATES. THE CONTACT TOOK THE VEHICLE TO THE DEALER AND THE DEALER CHANGE THE MASS AIR FLOW METER. THAT DID NOT REMEDY THE THROTTLE FLUCTUATION SO THE DEALER REMOVED THE MASS AIR FLOW METER. THE DEALER THEN RESET THE COMPUTER FOR THE THROTTLE BODY AND THAT DID NOT REMEDY THE ISSUE AS WELL. THE DEALER DOES NOT KNOW WHAT IS CAUSING THE THROTTLE TO FLUCTUATE. THE CONTACT STATED THE THROTTLE FLUCTUATION IS CAUSING THE VEHICLE TO LUNGE FORWARD WHEN THE VEHICLE IS IDLE. THE FAILURE MILEAGE WAS 94,500.
