Forgive my ignorance I have a 2006 CDI and don't even know the body# so I can look in the archive. It has 36,000 miles and the preglow light came on for 30 seconds on Sat after the engine cranked the car ran fine. When I started to work this morning the preglow came on again with the check engine light also. What's going on? The preglow has never come on before. Any help is appreciated
