audi engine light q5 2013 2.0T gasoline

Question

My yellow engine light turned on and i took it to the dealer. The scanner reads that there was a voltage drop when ignition. So they erased the warning and said everything is perfect. 2 days later the light came on again. What should i look for or expect in terms of issues and parts that need to be changed.

Thank you.

Battery light turned on? This is for the hybrid models, You need to get the "P" code just to verify the cause. When the hybrid drive does not work the hybrid light is illuminated, If the code you get is P0AD600 this would be a software issue for the Hybrid battery pack airflow valve ,
