Is the 0.9 TCe reliable?

The 0.9 TCe (H4Bt) is a three-cylinder turbo with a good reliability reputation, better than that of its sibling the 1.2 TCe: it does not share the same oil consumption or the same rate of chain problems. Its most-cited weak point is a coolant leak at the thermostat housing, which if ignored can end up damaging the head gasket; chain, turbo and lambda sensor cases appear less often.^[1][2]

Is the 1.6 and 2.0 8v EA827 reliable?

Simple, naturally aspirated petrol engines that, according to the sources, last a long time with regular maintenance. Gebrauchtwagenberater describes the 8-valve 1.6 as old-fashioned but reliable, and the 102 hp 1.6 MPI as even more reliable than the 1.4 16v. Watch the timing belt with the water pump, coolant leaks, oil consumption (especially on the 2.0) and idle and sensor faults.^[3][4][5][6]
