Oil consumption

Higher oil consumption can occur due to worn piston rings or valve seals, leading to frequent oil top-ups.

Engine knocking

This can be caused by using lower octane fuel than recommended, carbon buildup, or issues with the timing.

Fuel injector issues

Dirty or clogged fuel injectors can lead to poor fuel economy and misfires.

Timing chain/belt problems

Timing chain or belt wear can cause engine performance issues and, if not addressed, severe engine damage.

Cooling system failures

Problems with the radiator, water pump, or thermostat can cause the engine to overheat.

Misfires

Misfires can be caused by faulty spark plugs, ignition coils, or fuel delivery issues.

Sensor failures

Malfunctioning sensors such as the MAF, O2, or knock sensor can lead to various engine performance problems.

Turbocharger issues (if equipped)

Problems with the turbocharger can lead to reduced power and efficiency.

Cooling system issues

Problems with the radiator, water pump, or thermostat can lead to overheating, especially in high-performance engines like the GDI TAU.

Transmission problems

Although not directly related to the engine, issues with the transmission can affect overall vehicle performance, especially in a high-torque engine.

Exhaust system problems

Leaks or blockages in the exhaust system can lead to reduced engine efficiency and increased emissions.

Fuel system contamination

Contaminants in the fuel system can cause clogging of injectors and fuel filters, affecting engine performance.

Battery and electrical issues
