2015 消費者報導 "a settlement to a class-action lawsuit against Audi would extend the powertrain warranty on its 2009 to 2011 model-year CAEB 2.0-liter turbo engines to eight years or 80,000 miles. Audi declined to comment on the litigation or oil-consumption problems in general. Our data shows that newer Audi 2.0-liter turbos and V6 engines are also burning oil"
We focused on 498,900 vehicles from the 2010 to 2014 model years, many of which are still under their powertrain warranty. Several engines emerged as the main offenders: Audi’s 2.0-liter turbocharged four-cylinder and 3.0-liter V6, BMW’s 4.8-liter V8 and twin-turbocharged 4.4-liter V8, and to a lesser extent Subaru’s 3.6-liter six-cylinder and 2.0- and 2.5-liter four-cylinders.
