Disadvantages of the Mini B48A20A engine
Up until 2017, engines’ timing chains stretched rapidly before the design was altered; idle speed frequently floats as a result of a tank ventilation valve failure;
After 100,000 kilometers, oil consumption and tan valve stem seals are common; at high mileage, Vanos phase regulators and the Valvetronic system fail.
