• Engine stall - turbo failure investigation # EA22001

  On march 29, 2021, the office of defects investigation (odi) opened preliminary evaluation (pe) 21-009 after the agency received 58 reports alleging engine stalling in 2013-2016my audi vehicle models a8, s6, s7, s8 & rs7. The subject vehicles are equipped with a 4.0l, twin-turbocharged engine. Complainants reported that the vehicles stall suddenly with no warning while driving on the highway or in city traffic. Several of the complainants alleged an inability to restart. The complaints allege the major contributing factor to the engine stalling is the failure of the turbochargers. The complaints further allege the turbocharger failure is a result of oil starvation due to a clogged oil strainer.The location of the oil strainer in the turbocharger oil supply line is in the inner valley of the engine. It is not easily accessible, making regular service difficult. The oil strainer removes dirty particles and carbon deposits from the oil before flowing to lubricate the turbochargers. Over time, if the debris is not removed from the oil strainer, it clogs the strainer and prevents free flow of oil to the turbochargers and causes the turbine bushings to run dry and overheat resulting in turbine shaft failure due to thermal stress. In vws response to odis information request letter, vw provided approximately 611 warranty claims with unique vins, 70 field reports and 45 consumer complaints. These reports allege engine stalling due to turbocharger failure similar to the nhtsa reports described above. To date, nhtsa has received approximately 98 allegations of stall due to turbocharger failures. The total of 709 reports shown in the table above eliminates all duplicate reports received by both odi and the manufacturer.An engineering analysis (ea) has been opened to further assess the scope, frequency, and potential safety related consequences of the alleged defect, engine stalling due to turbocharger failure.The odi complaints cited above can be viewed at www.Nhtsa.Gov under the following odi identification numbers:11452589, 11452584, 11452383, 11450995, 11450988, 11449661, 11447092, 11442867, 11440536, 11440052, 11439959, 11438691, 11436461, 11435619, 11431661, 11429704, 11429584, 11426929, 11424203, 11423603, 11423337, 11421084, 11420626, 11420342, 11418884, 11418437, 11418433, 11417635, 11417351, 11416095, 11414235, 11413359, 11413214, 11413285, 11413133, 11407510, 11407450, 11407289, 11406821, 11406416, 11406291, 11406277, 11406273, 11406256, 11406251, 11406229, 11406222, 11406204, 11406197, 11406182, 11404665, 11404426, 11404348, 11403430, 11403268, 11399435, 11397821, 11396241, 11394763, 11391037, 11388662, 11387166, 11377446, 11363283, 11354107, 11344193, 11342497, 11342360, 11340302, 11325065, 11324163, 11322168, 11321144, 11318477, 11306754, 11279429, 11268109, 11256706, 11252723, 11246579, 11234853, 11234714, 11231582, 11231013, 11230589, 11229484, 11222281, 11218822, 11218749, 11217604, 11209168, 11209142, 11197149, 11191243, 11175842, 11170776, 11164032, 11152418.

The passenger side turbo failed. Yes it’s available for inspection. I was driving and i felt a pop, like a backfire from under the hood. The car lost power instantly and was any under power anymore on the road. It could have been a lot worse if i was on a busy highway but luckily was on a street with do one behind me. It was confirmed it was the turbo failure and the turbo has been inspected. No warning lamps or any prior symptoms before hand. Once it happened it started throwing warning lights for pretty much everything. Limited slip diff, air bags, epc, tpms, check engine light and traction control warning lights all went off one after the other.

On 09apr2021 i was driving on my way to pick up my dogs from daycare. During my ride the car seemed hesitant with power. When i arrived at the daycare and parked the car essentially seemed like it was choking and at one point completely shut off on it's own. After i picked up my dog i tried starting the car and it took 3 attempts for it to start. On the way home i had to try and keep the car in motion in order to keep the engine on, so every red light was a game. Moving though rush our in the city was very difficult and the care nearly died 3 times. I made it home and the car turned off on it's own, when i parked. I made an appointment with audi and brought the car in the next morning - on the way in the car died on while in motion approaching a red light on a city street. It inadvertently stopped traffic until i could put the car back in park, and attempt to start the engine twice, before it started again and i was able to drive the rest of the way to the dealership. The dealership diagnosed it as blown turbos.

Oil screen interior of engine (non-serviceable) clogged which prevented turbo chargers from receiving oil. Both turbo chargers failed which causes engine to stall. Was driving at 25 mph on two lane city street. Engine died, power was lost, and steered vehicle to avoid collision with brick mailbox. Brought vehicle to a stop in roadway (no shoulder) but was blocking traffic. Car would not restart. Towed vehicle to audi dealer who diagnosed turbo failure from clogged oil screen and presented a $12,732.74 quote for labor and replacement turbo chargers. Dealership noted that this is common failure with stock and turned cars and they perform this replacement multiple times a month per audi tsb. Tuned vehicles are immediately denied warranty despite there more than 131 reported cases on one owners group/volunteer website (https://www.Audizine.Com/forum/poll.Php?Pollid=4500&do=showresults). My vehicle received oil change and 40k service from audi dealership less than 5,000 miles prior to this failure. Oil screen replacement requires 20 hours of labor to tear the engine down to get to the part (non-serviceable) - technical service bulletin 2044640/9 (revised 3 times over 3 years to replace oil screen with upgraded screen - rev g). Have visited with multiple audi dealerships to obtain competitive quotes and learned that it is a common issue with the 4.0 v8 engine with failures normally occurring at 65k - 85k miles in a8, s4, s6, s7 models and that the repair is normally $11-12k per incident.

I was accelerating with traffic while on an on ramp and merging into busy traffic on the interstate, when suddenly i lost power and my car began to decelerate at a rapid pace. There was no throttle when the gas pedal was being pressed. Seconds after that i lost power to the car. Luckily, i was able to put my hazards and coast through 2 lanes of traffic to the shoulder. During which time, i had no power steering and had to fight to move the wheel. I had the car brought to my audi mechanic who said it sounds like your turbos blew and that was indeed the case. He said he sees it all the time on the 4.0 tt engines because of audis poor oil screen design that starves the turbos of oil and leads to the seizing up and breaking.

Power significantly reduced. Clear loss of boost. Eventual complete engine stall. I was fortunate to have been pulling into a parking spot when the engine cut off uncommanded. The car had to be towed to a repair shop. It was later determined the turbos had failed due to a loss of oil supply. The oil supply is cut off due to the singular turbo oil screen being clogged. Regular oil changes are documented at correct intervals. Audi after the middle of my2016 installed a revised turbo oil screen to help prevent this from happening. It is a known fault at audi and should absolutely be a recall to replace the oil screens with the revised versions. It is a major safety issue when the engine can suddenly stop running at any speed.
