Xoutpost.com - "Service Engine Soon" Wont go out!

So I should probably start where this all started. Back in February (super bowl weekend), I was up at the cabin in Glacier, WA snowboarding like I do every weekend during the snowboarding season. Well my trusty roommate took the X out during a windstorm to get Food and a tree fell in front of him on the road and he smacked it head on. So it got towed, and fixed in Bellingham, WA.. got it back, looked great, one thing, service engine soon light wouldn't go out. Had Harmony Motors take a look at it (German car guru's in Bellingham), couldn't get it to clear. Well I was leaving the Next morning for a Western Pacific Deployment on the USS Abraham Lincoln, so I had no choice but to take my car with me with the S.E.S. light illuminated still. The owner ensured me that the X was fine and that it passed all tests, but for some reason, EVERY single error message that would cause the light to come on, was coming on... So I think it might be a harness somewhere and I was wondering if anyone had a good idea on where to look or maybe you can give me some better insight on the subject. The X is now out of warranty and I really don't feel like paying the stealer to plug a harness back in. If all else fails I guess I can talk it over with the owner of Harmony and see if they would be willing the finish the work they started but didn't complete for free. thanks guys.. greg
