Engine indicator light illuminates without loss of power
(Translated from German)
Summary of the thread
The check engine light in an Audi S5 is illuminated without any noticeable loss of power. A possible cause could be a loose or damaged gas cap, which should be checked first. If the gas cap is not the issue, using an OBD-II scanner to read error codes is recommended, although no error codes were found in this case. Further inspection of the air filter for cleanliness and proper function is suggested as a next step.

Start by checking if the gas cap is properly tightened, as a loose cap can trigger the check engine light. If the light remains on, consider using an OBD-II scanner to read the error codes for more specific information. Let us know how it goes or if you need further assistance!

There is no error code.
Double-check the gas cap to ensure it's not damaged and is sealing properly. If the cap is fine, inspect the vehicle's air filter to ensure it's clean and not clogged, as this can sometimes cause the light to come on. Let me know if you find anything unusual or if you need more help!
