Problems:
Dynamic brake support (dbs) malfunction
The DBS system may fail to activate properly during emergency braking situations, which can compromise stopping power and increase the risk of collision.
Engine misfire
Misfires can occur due to issues with spark plugs, fuel injectors, or ignition coils, leading to rough idling, reduced power, and increased emissions.
Turbocharger problems
If the turbocharger (if equipped) fails, it can result in a significant loss of power, reduced fuel efficiency, and increased exhaust emissions.
Oil leaks
Gasket and seal failures can lead to oil leaks, which can cause engine damage and reduced performance if not addressed promptly.
Cooling system issues
Problems with the radiator, water pump, or thermostat can cause the engine to overheat, potentially leading to severe engine damage.
Fuel system contamination
Impurities in the fuel system can clog injectors and affect engine performance, leading to rough running and poor fuel economy.
Timing chain wear
Over time, the timing chain can stretch or wear out, leading to poor engine performance, unusual noises, and potentially catastrophic engine damage if it fails.
Electrical problems
Faulty sensors or wiring issues can lead to a variety of engine performance problems, including stalling, poor acceleration, and inconsistent power delivery.
