How to Troubleshoot Engine Misfires in the Audi A6?

I have been experiencing frequent engine misfires in my Audi A6. The check engine light keeps coming on, and the car shakes and feels less powerful when accelerating. How can I diagnose and fix this issue?

First, check the spark plugs and replace if necessary. Next, inspect the ignition coils for any cracks or corrosion. If those are not the issue, it could be a fuel injector problem. Have a professional diagnose and replace if needed.

Another possible cause could be a clogged air filter. Make sure to check and replace if needed. Also, have a diagnostic scan done to check for any error codes that may point to the source of the misfires.

One last thing to check would be the fuel pump and fuel pressure. If the fuel pressure is low, it could be causing the misfires. It's best to have a mechanic perform a fuel system check to determine the root cause.
