From 2008 to 2013, the American versions of several well-known models, including the A4, A5, A6, and Q5, were equipped with the Audi CAEB or A4 2.0 TFSI 2.0-liter turbo engine. The motor functioned as an analog of the European CDNC unit and was modified to meet ULEV 2 environmental standards.
The EA888 gen2 series includes: CDAA, CDAB, CDHA, CDHB, CCZA, CCZB, CCZC, CCZD, CDNB, CDNC, CAEA, CAEB.

Disadvantages of the Audi CAEB engine
The engine’s notoriously high oil consumption is caused by an unsuccessful piston group; the only way to eliminate the oil burner is to replace the pistons, such as forged ones;
Rapid coking and unstable engine operation are caused by persistent oil burnout; the timing chain has a limited resource and occasionally travels less than 100,000 kilometers;
The engine’s water pump, injection pump, and ignition coils are also weak points.
