Disadvantages of the M275 E55 engine
- The most famous problem with this engine is the impressive oil consumption.
- The cylinder block is aluminum and the cause of the oil burner is usually badass.
- It is also worth overheating the motor a couple of times and the grease will start to climb out of all the cracks.
- There are also rather unreliable and expensive blocks of ignition coils for 24 candles.
- The double-row chain has a not very long resource and is often extended to 200,000 km.
