the engine and its cooling

On March 29, 2021, the Office of Defects Investigation (ODI) opened a 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 equipped with the 4.0L, twin-turbocharged engine. Complainants reported the vehicles would stall with no warning while driving at highway or city traffic speeds. Several of the complainants alleged an inability to restart. The complaints alleged the major contributing factor to the engine stalling was the failure of the turbochargers. The complaints cited the turbocharger failure was a result of oil starvation due to a clogged oil strainer in the turbocharger oil supply line.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 servicing the component difficult. The oil strainer removes particles and carbon deposits from the oil before lubricating the turbochargers. Over time, if the debris is not removed from the oil strainer, it becomes clogged and prevents oil from flowing to the turbochargers. This causes the turbine bushings to run dry and overheat resulting in turbine shaft failure due to thermal stress.On April 04, 2022, PE21-009 was upgraded to an Engineering Analysis (EA22-001) to further assess the scope, frequency, and potential safety related consequences of the alleged defect. Volkswagen filed recall 22V-178 to replace the 30?m mesh oil strainer with a 90?m mesh oil strainer in the subject vehicles. VW introduced the larger mesh oil strainer into production in March of 2017 effecting the 2017-2018MY vehicles.ODI reviewed information from VW for vehicles that had the larger mesh installed in production. The data received showed, since the new oil strainer size of 90?m went into production for the 2017-2018MY, there has not been any reported incidents of turbocharger failures due to oil starvation or other failures that could be related to the larger screen mesh. In view of the recall being conducted by VW and lack of any detrimental side effect to the turbocharger caused by the larger mesh, ODI is closing this Engineering Analysis (EA). The agency reserves the right to take additional action if warranted by future circumstances.11502847,11506565,11494663,11488813,11486393,11480926,11479882,11476289,11466761 11464663,11463254,11460580,11460496,11458973,11458804,11457556,11454753,11452668 11452589,11452584,11452383,11452175,11452111,11451724,11451724,11450995,11450988 11449661,11447092,11443657,11442867,11440536,11440052,11439959,11438691,11436461 11435619,11433925,11433733,11432336,11431661,11431421,11429704,11429584,11428128 11426929,11424203,11423603,11423337,11422431,11421084,11420626,11420342,11419693 11418884,11418437,11418433,11418135,11417635,11417351,11416095,11414578,11414235 11414064,11413359,11413285,11413214,11407510,11407450,11406897,11406821,11406637 11406460,11406416,11406291,11406287,11406277,11406273,11406263,11406256,11406251 11406229,11406222,11406208,11406204,11406197,11406182,11406015,11404665,11404426 11404348,11403823,11403430,11403268,11402684,11399435,11397821,11396241,11394763 11391037

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 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. Overtime if the debris are not removed from the oil strainer, it clogs the strainer and prevents free flow of oil to the turbochargers and makes the turbine bushings to run dry and overheat which causes the turbine shaft to break due to thermal stress. In VW's response to ODI's 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 824 reports shown in the table above eliminates duplicate reports received by both ODI and the manufacturer.This Preliminary Evaluation is being upgraded to an Engineering Analysis (EA) to further assess the scope, frequency, and potential safety related consequences of the alleged defect of engine stalling due to turbocharger failureThe 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.

towed

After exiting the highway the car just stopped running. There was no warning and all power was lost. Engine would not start up and vehicle had to be towed from the road. It was at night and the car stopped dead at an intersection (safety). We are grateful that the problem did not happen on the Ohio Turnpike we just exited. There was a clunk sound before it stopped. I suspect the turbo let loose. This has not been confirmed yet by the dealer. There was no warning. Consumer stated vehicle has been repaired.

The contact owns a 2013 Audi A8. The contact stated that while her son was driving at highway speeds, the warning lights on the instrument panel flashed as the vehicle shut off. The contact's son managed to pull over despite the failure. The vehicle was initially towed to one dealer; however, the dealer failed to service the vehicle promptly. The vehicle was then towed to a dealer where it was diagnosed with a defective ECM(Electronic Control Module) that needed to be replaced. The vehicle remained in the dealer's possession for a month before the vehicle was repaired. Despite the repair, the contact was notified that the failure persisted and was then informed that a defective engine …

The pcv oil separator has failed and is making a whistling sound. From researching this issue it is widely known and an investigation shows it is caused in relation to a recall for the oil strainer that was done on this vehicle. I called audi dealership and they said this is not an open recall, however it seems this is exactly what caused it.

Audi, A8L 2013, also has the stuck piston. Rings end oil blow by like the other Volkswagen, defected engines of the same year yesterday while driving my car ended up stalling on a road with traffic behind me going up a hill because too much oil I'd burnt in the cylinders, causing the spark plugs to become completely coated in oil and the cars. Electronic system registered multiple misfires, multiple cylinders. Are misfired and multiple other safety epc codes, causing the vehicle to not be able to drive more than 5 miles an hour, stuttering. Which also caused the engine to almost stall, losing power steering. If this was on the highway this could have been exceptionally bad. I request the …

NHTSA complaint 11610338, quoted in part. Filed by an owner and not verified by NHTSA or by us.

Brake pedal is hard when starting the vehicle. Brake pedal turns soft when engine is started. The brake pedal is so hard that it requires significant force to depress sufficiently to start the engine. This indicates loss of vacuum in brake booster when engine is off. The vehicle is equipped with a start/stop system and it seems likely that the brakes would not sufficiently hold the vehicle when the start/stop system turns off the engine.
