NHTSA Complaint #11414064 — 2014 AUDI S6

DURING A 500 MILE ROAD TRIP FROM IA TO MO I EXPERIENCED THE FIRST SYMPTOM. I WAS ABOUT 5 HOURS INTO THE TRIP, CRUISE WAS SET AT ABOUT 70MPH. ALL OF THE SUDDEN A 'SHUDDER' WENT THROUGH THE CAR, LIKE THE CAR COMPLETELY LOST ALL POWER FOR A MOMENT. GETS YOUR ATTENTION IN A HURRY! I CHECKED ALL THE GAUGES, AND THERE WERE NO ERRORS AND EVERYTHING APPEARED IN ORDER. WE WERE ABOUT 15-20 MINUTES FROM THE DESTINATION, SO WE DECIDED TO SEE IF WE WOULD HAVE ANY TROUBLE MAKING IT. WE MADE IT THE REST OF THE WAY DOWN WITHOUT INCIDENT. THE NEXT DAY WE HAD TO DRIVE BACK TO IA. IN GENERAL THE CAR DROVE OKAY. ALTHOUGH WE DID EXPERIENCE THE SHUDDER ABOUT 4 TIME ON THE TRIP HOME. I WAS SURPRISED THAT WE MADE IT, BASED ON THE FIRST SHUDDER. ONCE I GOT HOME I DECIDED TO INSPECT THE TURBOS, AS THEY HAVE A FAILURE HISTORY IN THESE CARS. I USED A BORESCOPE TO CHECK THE TURBOS. THE PASSENGER SIDE TURBO HAD OIL IN THE INTAKE, INDICATING OIL WAS LEAKING FROM THE TURBO COMPRESSOR SEAL. THERE WAS ALSO SLIGHT SCRAPING OF THE COMPRESSOR BLADES ON THE HOUSING, INDICATING THE INITIAL STAGES OF FAILURE. THE CAR WAS PARKED UNTIL I COULD GET A CHANCE TO PULL EVERYTHING APART. THIS WEEKEND I PULLED THE CAR APART. I FOUND A PLUGGED TURBO OIL SCREEN BURIED DEEP IN THE VEE OF THE ENGINE. THE ORIGINAL OIL SCREEN WAS DEFORMED IN THE DIRECTION OF OIL FLOW, INDICATING THE RESTRICTION TO FLOW THAT IT HAD CREATED. I HAVE ATTACHED PICTURES OF THE EXISTING OIL SCREEN AND A BRAND NEW OIL SCREEN HELD UP TO A LIGHT. THIS IS TO INDICATE THE LEVEL OF BLOCKAGE ON THE ORIGINAL SCREEN. CAR HAD 91,828 MILES WHEN IT WAS SCOPED. I HAVE OWNED 16 AUDI'S OVER THE YEARS, 9 WITH TURBOS. THIS IS MY FIRST TURBO FAILURE EVER. I HAVE TAKEN MANY OF THE CARS UP AROUND 200K MILES, WITH A FEW SURPASSING IT BEFORE BEING TRADED.
