Today we're tackling the check engine light on my 2005 E46 wagon by diagnosing and resolving the secondary air system. For the first part of the video, I build you a diagram and show the basics of the system and how it works. Then we fix the system on my BMW so you can see hands on how it works and how to test each component!
Hope this video help you out, and thanks for watching! Don't forget to check out The Bimmer Barn store to grab some merchandise, and get exclusive access to EXTRA content through our Patreon! :)
