Disadvantages of the Audi BYT engine
Information regarding the dependability of this engine, which was only manufactured for six months, is at least
The manufacturer modified the crankcase ventilation system during modernization, most likely as a result of its issues;
Every engine in this series has a limited timing chain resource—sometimes less than 100,000 kilometers;
The catalyst, pump, and ignition coils are the engines’ weak points; the network frequently complains about floating speed caused by soot on the intake valves.
