Engine indicator light and start-stop fault during heavy acceleration

Hello everyone, I have a problem with my 2016 Audi A3 8V. Whenever I accelerate faster, the yellow pre-glow light comes on immediately. If I accelerate further, the check engine light also comes on. The car also indicates that the start-stop function is faulty. When reading out the error codes with my adapter, I get the following error codes: 1. exhaust gas recirculation: excessive flow detected 2. mass or volume airflow Circ: Range / power The problem occurs particularly as soon as I accelerate a little faster and immediately from 100 km/h. Can anyone help me find out what the cause could be and how I can solve the problem? Many thanks in advance!

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!
