S6

  • 49,996 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.
