Turbocharger issues
Turbochargers can fail or wear out, leading to reduced engine performance or failure.
Carbon buildup
Direct fuel injection engines are prone to carbon buildup on intake valves, affecting performance.
Cooling system problems
Radiator, water pump, or thermostat issues can lead to overheating.
Fuel injector problems
Fuel injectors can become clogged or fail, leading to poor fuel delivery and engine performance.
Sensor failures
Various sensors (O2, MAF, etc.) can fail, leading to incorrect engine management and performance issues.
High oil consumption
Some engines may consume more oil than normal, requiring frequent top-ups.
