1.6 THP vs VR6: which engine is more reliable?

According to our risk index, the VR6 carries less risk than the 1.6 THP: 50/100 versus 64/100 (both high risk). The 1.6 THP has 2 documented serious faults, the main one being «Timing chain and tensioner stretch (turbo versions, before 2012)»; the VR6 has 1 documented serious fault, the main one being «VR6 timing chain and tensioners».

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.^[1][2][3][4]

See the 5 of the 1.6 THP faults

Is the VR6 reliable?

Its best-documented faults are the timing chain, with tensioners on the 12-valve versions and stretching on the 3.2 (R32, A3 8P, TT, Cayenne), and, to a lesser extent, the cooling system of the 12-valve versions. The 3.6 FSI comes out of the sources better than the 3.2.^[5][6][7]
