Disadvantages of the Mini B38A12A engine
- So far, the main complaints are related to the vagaries of direct injection and soot on the valves;
- The weak point of the engine is the thermal module, which here replaces the thermostat;
- Periodically, problems are thrown up by Vanos phase regulators or the Valvetronic system;
- Sometimes the thrust bearing is destroyed due to the large axial clearance on the crankshaft.
