Is the 1.8 and 2.0 XU reliable?

These are naturally aspirated 1.8 and 2.0-litre petrol engines with no serious documented design faults outside the 16-valve timing belt: the 1.8 16v built until late 1997 had a recall for premature breakages, and the 2.0 16v in the GTi-6 calls for shorter belt change intervals. The rest are minor faults: coolant and oil leaks, sensors and idle.^[1][2][3][4]

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.^[5][6][7][8]
