Possible cause described
A buyer’s guide explains that Alfa halved the timing-belt interval on the petrols (about 58,000 km or 3 years), that the water pump should be changed with it because its plastic impeller breaks, and lists the air-flow meter, the electrics and the gearbox seals as weak points.
