Engine Overview and Common Failures

The weight of the M54 engine according to the catalog is 170 kg. The engine number M54 is located at the junction of the block and the oil pan. This engine is very sensitive to overheating, so please monitor the condition of the cooling system. The piston rings are too thin and tend to wear out quickly, causing excessive oil consumption. Another source of lubrication loss is the crankcase ventilation valve. The DISA flaps in the intake manifold often get stuck and can crack. Poor quality oil can damage the hydraulic lifters and the Vanos variable valve timing unit. Electrical issues commonly occur with the camshaft and crankshaft position sensors. Valve cover leaks with oil seepage into the spark plug wells are also known to happen.
