This is a very reliable engine with long life and no serious flaws. Its weak points include a rather finicky ignition system. There are many forum topics about unstable engine operation and solutions after replacing the ignition coil or its high-voltage wires.
Beta series engines are quite demanding on oil quality and change intervals. Saving on oil often leads to camshaft phaser failure before 100,000 km, and using very thin oils at high mileage can cause bearing shell spin.
In these engines, the crankshaft is connected to the exhaust camshaft by a belt, whose official service life is about 90,000 km. Dealers play it safe and replace it every 60,000 km, because if the belt breaks, the valves bend.
Owners also complain online about noisy and even harsh operation, low lifespan of auxiliary components, and malfunctions of the ECU and temperature sensor.
