For the past week my exhaust engine light has been coming on. Until today it would go off after about 30 minutes of driving by restarting at a light, or pulling over and restarting. Today however I can not get the light to go off. My 2006 TDI has 136K miles on it. The manual simply says that there is an exhaust failure. I pulled off the O2 sensor and cleaned it with wire brush, but that did not fix the problem. . The car is running fine and I do not notice any difference in performance. Can anyone give me some ideas as to what might be causing the light to come on and stay on?
