Engine Overview and Common Failures

The weight of the N45 engine according to the catalog is 130 kg. The engine number N45 is located at the junction of the block with the cylinder head. Poor quality fuel often leads to detonation and damage to the power unit. The timing chain mechanism has a relatively modest lifespan, especially its tensioner. VANOS phase regulators also do not last long, they can start making noise even before reaching 100,000 km. Oil seals wear out at approximately 80,000 km and oil consumption begins.
