Disadvantages of the Mini N14B16A engine
- The most problematic here is the capricious direct fuel injection system;
- In second place is a large consumption of lubrication and increased coking in the intake;
- The timing chain has a modest resource here, often it runs less than 50,000 km;
- The vacuum pump is not very reliable, as well as the Vanos phase regulator;
- Another weak point of the engine is the thermostat, water pump and lambda probes.
