Interesting what you found Dom. I do have to side with Daryl. The impact energy must have caused the wire clip to pop out?
The only supporting evidence I can offer is what happened to my car. My first yr of ownership I was at a show in Atlantic City. Ron K, then our VP, was there and in true BOB spirit came over to welcome the NooB!
He found that my left front actuator clip had engaged only one of the locking slots on the cup.... "you gotta check this stuff as these clips doesn't have all that much locking tension." God knows how long it was like that. The system worked, no DTC's, but the clip was only engaged in one slot. I would have to think your clip might have had a similar condition, and the impact energy knocked it off?
