Frequent problems
BMW M54B22 engines are characterized by problems of high oil consumption, overheating, and misfiring. If the piston rings are carbonized, oil consumption increases. You need to make a replacement. The crankcase ventilation valve often requires replacement. When the red oil light is on, check the oil pump and oil cup.
If the engine overheats regularly, check the operation of the cooling system, the condition of the pump, thermostat cap and radiator. When misfiring is observed in the engine, the cause is coked hydraulic lifters.
Among the common problems of the BMW M54B22 engine are the failure of the camshaft position sensors, wear of the thermostat. Also check the threads on the cylinder head. Timely maintenance will ensure long engine life.
