0.9 TCe vs 2.0 FSI: which engine is more reliable?

According to our risk index, the 2.0 FSI carries less risk than the 0.9 TCe: 34/100 versus 49/100 (both moderate risk). The 0.9 TCe has 3 documented serious faults, the main one being «Coolant leak at the thermostat housing»; the 2.0 FSI has no documented serious faults.

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 2.0 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.^[3][4][5][6]
