At some point in most VW owners life they will get a check engine light. For about the 4th time in my Passat’s life, the check
engine light came on. I would say that is pretty good for over 140,000 miles. The check engine light can come on for a ton of different reasons. Today I am going to walk you through my diagnostic process for check engine lights. At the start of the video, I did not know what was wrong with the Passat. You get to see exactly the point we find the issues.
