Is the 2.0 FSI reliable?

The 2.0 FSI is the naturally aspirated version with which the Volkswagen Group introduced petrol direct injection in a two-litre engine, before moving on to the turbocharged 2.0 TSI. Two faults recur across several models: carbon build-up on the intake valves, inherent to direct injection, and ignition coil failure, documented from 5,000 km in one case. Gebrauchtwagenberater.de nevertheless counts it among the most reliable petrol engines in the Audi A4 B7.^[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]
