Keep me posted, I'm curious to know if it'll wind up being one of the many reasons mine has come on in the past. Since they replaced the supposedly bad o-ring though, I haven't had any issues (knock on wood!). They actually photocopied the mechanic's notes for me so I could see the steps he went though to diagnose the problem. I was actually rather impressed with the effort he put in to it instead of just replacing another part like the other dealership did. We'll see if his efforts will be rewarded. Good luck!
