Engine

“The car was running rough for a couple weeks; hesitant to accelerate, failed to start multiple times and idled rough. One day I was coming home from my hour long commute, I put the car in reverse in my driveway and the car started bucking so badly that it became un-drivable. At this point we had to get the car towed on a flatbed an hour away to the nearest dealership and this is when we discovered that the turbos had gone bad. There was no check engine light or any indication before it just failed. I am active duty in the United States Coast Guard and being without a car is not an option. Because of the shipping delay and waiting for the turbos to come from Germany, I was without my car for two weeks. I was loaned a vehicle but I had to rent a car for one day in between. We have been told by Audi dealerships for years that this was a known problem and to expect this $10,000 repair.”

“WHILE ON THE HIGHWAY, I NOTICED THAT THE CAR WAS NOT PICKING UP APPROPRIATE SPEED WHEN ACCELERATING. THERE WAS NO PRIOR NOTICE OR ENGINE LIGHTS OR ANY ABNORMALITIES WITH THE VEHICLE PRIOR TO THIS. I DECIDED TO PULL OFF THE HIGHWAY AT A REST AREA AND AS THE CAR WAS SLOWED DOWN AROUND 15-20 MPH, I LOST TOTAL POWER OF THE VEHICLE AND WAS UNABLE TO STEER OR USE THE BRAKES. LUCKILY THE CAR WAS ABLE TO COAST TO A STOP WITHOUT INJURY BUT WAS EXTREMELY FRIGHTENING WITH MY FAMILY IN THE VEHICLE. AFTER TOW TO THE AUDI DEALERSHIP I WAS INFORMED THAT THE PROBLEM WAS A CATASTROPHIC FAILURE OF THE TURBOS IN THE ENGINE. I DID EXTENSIVE REVIEW OF THIS PROBLEM AND FIND OUT THAT IT IS A KNOWN PROBLEM AND BOILS DOWN TO A DESIGN FLAW WHERE A SMALL OIL SCREEN ESSENTIALLY STARVES THE TURBOS OF OIL. SOMETIME THESE SCREENS HAVE CLOGGED BUT IN MANY CASES ARE JUST FINE BUT IN ALL CASES HAVE LEAD TO TURBO FAILURE. THIS IS NOT A MAINTENANCE ISSUE AND ALL VEHICLES I HAVE REVIEWED HAVE BEEN FACTORY MAINTAINED WITH SERVICE RECORDS AVAILABLE SUCH AS IN THE CASE OF MY VEHICLE. THIS IS NOT CURRENTLY COVERED BY AN AUDI EXTENDED WARRANTY AND REPAIRS ARE VERY COSTLY AVERAGING AROUND 12-13K FROM…”
