1.2 12V vs VR6: which engine is more reliable?
According to our risk index, the VR6 carries less risk than the 1.2 12V: 50/100 versus 57/100 (both high risk). The 1.2 12V has 2 documented serious faults, the main one being «Timing chain stretch and tensioner wear»; the VR6 has 1 documented serious fault, the main one being «VR6 timing chain and tensioners».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.2 12V reliable?
The 1.2 12V is a simple, low-power, naturally aspirated three-cylinder engine (54-70 hp), with two documented design faults: the timing chain tensioner, which can end up destroying the engine, and -on the Volkswagen Polo IV- a catalytic converter too close to the cylinder head that can burn the exhaust valves. Ignition coil failures are also common, and there are isolated cases of oil consumption and vibration.[1][2][3][4][5]
See the 5 of the 1.2 12V faultsIs 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.[6][7][8]
