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 1.6 THP reliable?

The 1.6 THP turbo and its naturally aspirated sibling, the 1.6 VTi, make up the Prince family, developed together with BMW and also used by MINI: they do not have a reputation for reliability. Turbo versions built before 2012 carry a known problem of timing chain stretch, and the whole block shares a water pump described as fragile; the turbo versions add oil consumption and high-pressure fuel pump failures.[5][6][7][8]
