The VANOS (Variable Valve Timing) system relies on bolts that can fatigue and break. This is a critical engine component failure that can lead to significant engine damage if not addressed. Estimated repair cost: $1,000 - $2,500.

The electric fuel pump can fail, leading to a loss of fuel pressure and engine stalling. This is a critical component for engine operation. Estimated repair cost: $600 - $1,200.

The turbocharger system, essential for the N55 engine's performance, can develop issues. These can include wastegate problems or bearing wear, leading to reduced power and efficiency. Estimated repair cost: $1,500 - $3,000.

High-Pressure Fuel Pump (HPFP)

The direct injection system's high-pressure fuel pump is a known weak point on these engines. Failure can cause drivability issues and eventually prevent the car from starting. Estimated repair cost: $800 - $1,500.
