Hi, I can't offer too much more than sympathy because I have a different model, but mine, which is new, flashes an error code on the Intellipanel when unhappy. If you catch it there is a section in the back of the owner's manual to help decode it. Otherwise check to see if you followed the directions for the regen EXACTLY, which is easier said than done. It sounds as though it thinks you didn't do the regen. I found the directions to be as clear as mud. Beyond that a call to your dealer first thing Monday..
Good luck, and welcome!
