Is the 2.4, 2.8 and 3.0 V6 30v reliable?

The 30-valve V6 engines of the Volkswagen Group (2.4, 2.8 and 3.0) have few documented faults: there are few owner reviews, and they mention coils, the thermostat and oil leaks. The most sensitive item is the timing belt, which on the 2.8 also drives the water pump: Audi and VW ask for it to be changed every 120,000 km, and the job takes 2.9 to 3.5 hours.^[1][2][3][4]

Is the 0.8 / 1.0 / 1.2 S-TEC reliable?

The GM Daewoo S-TEC engines (0.8, 1.0 and 1.2 naturally aspirated, low power) power the Matiz, Spark, Aveo 1.2, Beat and Sail. The sources consulted document only minor and cheap faults, such as oil leaks and ignition faults on the Matiz, and we have found no structural engine fault.^[5][6][7]
