1.4 T-Jet vs VR6: which engine is more reliable?
According to our risk index, the 1.4 T-Jet carries less risk than the VR6: 48/100 (moderate risk) versus 50/100 (high risk). The 1.4 T-Jet has 1 documented serious fault, the main one being «Premature turbocharger failure or 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 1.4 T-Jet reliable?
Fiat's 1.4 T-Jet/MultiAir powers a large part of the group's turbo petrol range (Fiat, Abarth, Alfa Romeo, Lancia, Jeep) from 2007 onwards. Several models have accumulated reports of turbocharger failure, MultiAir/UniAir unit faults and high oil consumption; by contrast, there is no documented pattern of timing belt failure.[1][2][3][4][5][6]
See the 4 of the 1.4 T-Jet 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.[7][8][9]
