Is the BMW N20 reliable?

The BMW N20 (2011-2017) was the first turbocharged four-cylinder with which BMW replaced its naturally aspirated six-cylinders in models such as the 320i, 328i and X3, and it is generally mechanically sound. Its best-documented weak point is the timing chain guides and tensioner on units built before 2015; oil leaks, the electric water pump and, to a lesser extent, the turbo and the high-pressure fuel pump are also known issues.^[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]
