1.6 EcoBoost vs 2.0 FSI: which engine is more reliable?

According to our risk index, the 2.0 FSI carries less risk than the 1.6 EcoBoost: 34/100 (moderate risk) versus 59/100 (high risk). The 1.6 EcoBoost has 3 documented serious faults, the main one being «Cracked cylinder head from overheating, with fire risk»; the 2.0 FSI has no documented serious faults.

Is the 1.6 EcoBoost reliable?

It is a turbocharged direct-injection four-cylinder that Ford used between 2010 and 2018 as a mid-range step across much of its European line-up, and which Volvo sold under its own T3/T4 designations. Its most serious fault is overheating caused by a loss of coolant circulation that can crack the cylinder head and cause a fire: Ford has recalled cars in South Africa and in the US/Canada, although we have not confirmed an equivalent campaign in Spain.^[1][2][3]

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.^[4][5][6][7]
