Audi A4 Check Engine Light and Misfire Issue Without Power Loss

I own a 2014 Audi A4 with 113,000 km, and recently, the check engine light came on after I floored the accelerator. Upon scanning, it showed a cylinder 1 misfire and multiple misfire detected. I cleared the codes, and the car seems to run fine when not under wide-open throttle. There is no noticeable loss of power or jerking. What could be causing these misfires, and should I be concerned about potential underlying issues? Any advice on troubleshooting or necessary repairs would be greatly appreciated.

A 2014 Audi A4 owner experienced a check engine light and misfire codes after flooring the accelerator, though the car runs fine otherwise. Possible causes include worn or damaged spark plugs and ignition coils, or clogged fuel injectors. Suggested solutions involve inspecting and potentially replacing these components, while monitoring the check engine light for further issues.

Start by checking the condition of the spark plugs and ignition coils, as these are common causes of misfires. Inspect them for wear or damage and replace if necessary. If the issue persists, consider checking the fuel injectors for clogs or issues. Keep an eye on the check engine light and let me know if the problem continues or if you have any further questions.
