The check engine light stayed on while the car was in motion. When the car was idling, the check engine light blinked. I was able to drive it to fairfax Volkswagen in fairfax, va to have the car checked out. Apparently there was a recall on the ignition coils, which had been out for over a year. I had no idea about the recall -- even after I took the Jetta to stohlman vw for service on my audio speakers in the fall of 2004. They never told me about the recall and it should have been repaired at that time. Fairfax vw told me that checking for recalls is their first priority, and that is how the recall was brought to my attention. I am very displeased with stohlman, and the service, or lack thereof, I received.
