I had a Jetta. One of the least hoopty hoopties I’ve owned. But as the years went on and miles piled up, in typical VW fashion, the check engine light would come on for no reason. Would pull codes and nothing. But of course inspection would fail.

It hadn’t come on for a few months so I took it in for a 3rd time that month to renew reg (would reset after about 100 miles). Sitting there in the inspection lane, light winks on. I screamed at the dashboard and it blinked off. I stared in disbelief for a moment and it passed.

Thought it was a fluke but, no — any time it came on after that I would scream and it would turn off.
