“Audi S6 4.0 tt, the car I own are notorious in oil screen problems. They starve the turbos with no oil and cause failure to them. I am one of the person that has to deal with the issue.”
NHTSA complaint #11406186, filed 2021-04, 30,000 miles“Turbo power feels to have gradually declined upon approaching 50k miles. It is caused by clogged turbo oil screens. $3000+ repair with no help from Audi brand and dealer for a widely known issue. Additionally the o2 sensors have randomly throw error for running lean. Replaced o2 sensor but issue came back. Have already tested maf sensor and vetted for vacuum, exhaust leaks. Also a known issue with no help from Audi brand/dealer.”
NHTSA complaint #11413599, filed 2021-04, 49,996 miles“I'm NOT sure if this would have developed to an safety issue, I'll let your team decide. At my scheduled 50,000 mile dealer service (50,219 miles) I was informed that both motor mounts had failed and needed replacement. The service rep said that THEY found a fault code for one mount and a visual inspection confirmed that the other mount had also failed. Both mounts had sensors but I DID NOT receive a Check Engine Light of any kind. If the situation would have continued, COULD this have become a safety issue? Maybe? …”
NHTSA complaint #11458739, filed 2022-03“Oem turbos fail on Audi 2013-2017 S6/s7/s8/rs6/rs7 due to oil starvation caused by clogged oem oil strainer. This is a safety issue as the failure happens without warning and as it generally happens while while driving the sudden loss of power could lead to a serious accident. This issue appears to be wide-spread based on discussions available on online forums. Audi is aware of these failures and has issued TSB's that identify the turbo oil strainer as the culprit but they have not issued a recall. …”
