Multiple turbo failures. Engine shook violently then suddenly stopped in the middle of the road. This same issue happened 3 times affecting both turbos. It may be due to faulty oil filter/strainer. From online research (link below) this is a common problem for C7 Audi s6. https://www.audizine.com/forum/showthread.php/851578-2016-S6-4-0T-Turbo-Failure

Driving on the New Jersey turnpike and both turbochargers failed. Car lost power and I had to steer to side of the highway without power steering and brakes from far left lane. Audi service says bearings starved of oil and seized. They said this is a common problem with the 4.0 twin turbo Audi engines and that the oil feed line gets blocked and starves the turbochargers of oil, resulting in bearing failure. Repair cost is $9,000. Car has less than 70,000 miles. Audi has a technical service bulletin on file with the NHTSA that specifically addresses this known problem. Audi North America will not assist with cost of repairs.
