Infotainment System Glitches

What goes wrong
Symptoms
1. Carbon Buildup on Intake Valves
Direct-injection petrol engines like the CHZB lack fuel spray across the intake valves during the induction stroke. Without this natural cleaning action, carbon deposits accumulate on the valve stems and seats, restricting airflow.[2]
2. Turbocharger Actuator/Wastegate Linkage Failure
The actuator linkage connecting the wastegate solenoid to the wastegate valve becomes faulty or loose, causing loss of boost control. Many repair shops misdiagnose this as full turbocharger failure and recommend a costly replacement (€1,000+) when only the actuator arm needs repair (€150).[3]
