Hi. I don't see where you got an answer. Did I miss it? I have a VW 2002 Passat Wagon with a 2.8. I TOO bought it from craigslist, and the day after I bought it...you guessed.....check engine light. Varies codes all arouund misfires, 300. 302, etc. It's been ongoing for over a year now. Never resolved. Bought some fancy ceramic type expander as it was thought it had something to do with low air compressionn Got air sensor, replaced spark plugs and wires. Had a scare because the check engine light, which had been off for about 3 months [a record] the check engine light came back on but FLASHING!! Not good. Codes 300, 301, 303 and 305. Light was off by the time I finished scan. Cleared. Took a drive. No more like. I took it for nice drive, no light. Ran scan. No code. Today light came back on, and the code said it was a 301. one really seems to have an answer. Not here either, huh? Well if anyone has any good ideas please let me know. I have to drive about 160 milestomorrow, and I'm a little nervous. Hope it doesn''t burn out my motor! Thanks.
