Disadvantages of the Audi BYT engine
- This engine was produced for only six months and information about its reliability is at least;
- During the modernization, the manufacturer changed the crankcase ventilation system, probably due to its problems;
- All engines in this series have a modest timing chain resource, sometimes less than 100,000 km;
- The network often complains about floating speed due to soot on the intake valves;
- The weak points of the engines of this line include the catalyst, pump and ignition coils.
