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. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
WHEN ENGINE IS COLD, USUALLY BELOW 0 DEGREES FUEL SPRAYS FROM INJECTORS. THIS COULD IGNITE ON EXHAUST MANIFOLDS CAUSING CAR FIRE.
