High-pressure fuel pump failure

The high-pressure fuel pumps in these engines can fail, leading to issues such as rough idling, stalling, and difficulty starting the vehicle.

Valve stem seal failure

This issue can cause the engine to burn oil, resulting in excessive oil consumption and smoke from the exhaust.

Timing chain problems

The timing chains in the N63 engine have been known to stretch or fail, which can cause severe engine damage if not replaced promptly.

Turbocharger issues

The twin-turbo setup can experience failures, resulting in loss of power and increased exhaust smoke.

Cooling system failures

Components such as the water pump and thermostat may fail, leading to overheating and potential engine damage.

Battery drain

Parasitic drains in the electrical system can lead to battery issues, causing the vehicle to not start or to have electrical malfunctions.
