The 3.0-liter Audi BUG 3.0 TDI engine was produced by the German concern from 2005 to 2007 and was installed only on the rather popular Q7 SUV in the 4L body. This unit relatively quickly gave way to a similar diesel engine with the CASA index.

Disadvantages of the Audi BUG engine
- Up to 100,000 km in the engine, except that the intake manifold flaps can disturb;
- Around this run, the injection pump belt often bursts, but usually without consequences;
- In the first years of production, there was a burnout of the pistons due to a defect in the piezo injectors;
- The timing chain lasts a long time, up to 300 – 350 thousand km, but its replacement is very expensive;
- At high mileage, the particulate filter or EGR valve may become completely clogged.
