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

Owner report 11675620 · 2025-07-23 (July 23, 2025)
Steering Module went out for no apparent reason. I was able to find a used one and have it repaired for just under $1000. I had git two quotes for to auto shops that specialize in Audi repairs and they were both over $5300 to repair this steering module. This is unacceptable.
