Audi A4 2002 Cabriolet 1.8 Turbo Quattro engine AMB
Engine reliability and common problems:
The main known problems for this engine are turbocharger failure, ignition issues, and unstable idle.The turbocharger frequently fails due to oil coking in the supply lines.
The ignition coils with built-in modules have a relatively short lifespan and often require early replacement.
Unstable engine idle is often caused by air leaks in the intake system, which disrupt proper airflow. Excessive carbon buildup typically results from malfunctions in the crankcase ventilation system.
Overall, this engine can last around 290,000 to 490,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
