Audi A3 Quattro persistent skipping and hesitating issue with check engine light on on Audi A3 Quattro

Some Audi A3 Quattro owners report experiencing persistent skipping and hesitating issues accompanied by a check engine light. This warning indicator often signals various problems within the vehicle's systems, including potential engine or emission control system failures. A common cause for these symptoms, particularly in 2.0L turbocharged engines, is a failed high-pressure fuel pump or worn camshaft components. While the check engine light may briefly illuminate during engine start-up, it should turn off once the engine is running smoothly. To accurately diagnose the issue, owners are advised to use an OBD scanner tool to retrieve diagnostic trouble codes (DTCs). It is recommended that affected owners consult a qualified mechanic or Audi specialist to address the underlying causes of these issues.
