A closer look at this job

This N62 upload is about cleaning secondary-air passages on a BMW V8. Deposits in those passages are the particular subject of the video, not a blanket diagnosis of every secondary-air fault. If you're investigating this system, use the footage to understand the physical area before checking your codes, model and service literature.
