Ladies and Gentlemen, The check engine light is activated on my Audi A6. The error code indicates that the efficiency of the particulate filter bank 1 is below the threshold. Does anyone have experience with this problem and can give me tips on how to fix it? Thank you in advance for your help. With best regards.

Summary of the thread

The check engine light on an Audi A6 is triggered by an error code indicating that the efficiency of the particulate filter bank 1 is below the threshold. This issue may be caused by a clogged particulate filter. A suggested solution is to perform a regeneration drive at highway speeds for 20-30 minutes to clear the filter. If the problem persists, a mechanic should inspect the filter for more serious issues.

Start by checking if the particulate filter is clogged. You can try a regeneration drive, which involves driving at highway speeds for about 20-30 minutes to help clear the filter. If the light remains on, it might be necessary to have a mechanic inspect the filter for any deeper issues. Let me know how it goes or if you have any further questions!
