A 2016 Audi A3 8V experiences a yellow pre-glow light and check engine light during heavy acceleration, along with a start-stop function fault. Error codes indicate issues with excessive exhaust gas recirculation flow and mass or volume airflow.

Start by checking the EGR (Exhaust Gas Recirculation) valve for any blockages or malfunctions, as this could cause excessive flow. Ensure that the valve is clean and functioning properly. Also, inspect the MAF (Mass Air Flow) sensor for dirt or damage, as it might be affecting the airflow readings. Clean or replace the MAF sensor if necessary. Let me know how it goes or if you have any further questions!
