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 2.3 VR5 (V5) reliable?

The 2.3-litre VR5 is a naturally aspirated five-cylinder with the timing chain at the rear of the engine. Gebrauchtwagenberater rates it as a buy with no known problems in the Golf IV, but in the Bora it warns that the chain sometimes stretches; AutoHints adds the coils and the plastic coolant parts as points to watch.^[3][4][5][6]
