Disadvantages of the Audi DUCB engine
- The engine is new, so there are few failure statistics yet;
- So far owners report only electrical glitches, mostly related to charging;
- The timing belt is replaced every 210,000 km, but if it breaks earlier the valves bend; a special tool is needed to replace it, and not every workshop has one;
- Like all direct-injection engines, it is prone to carbon deposits on the intake valves;
- The plasma-sprayed cylinder walls do not tolerate poor fuel.
