Read first 4 posts, coincidence or possible pattern? Some owners of 08 and 09's have stated intermintent problems with TBW. May have found common cause, tell your techs to check for this if they are having trouble locating cause, especially if they say your induction module is bad. Hopefully this might help someone and save some headaches.
