I've been getting the wrench off and on since I've owned it. First time it happened I was close to dealer and they pulled a soot code, and we were watching it. Every other time it has happened it clears on shutdown and leaves no code. happens either before regen and during regen when drive for regen is displayed. Recently had drive for regen, got wrench, and then had reduced engine power message. other than messages, everything looked okay but did not clear on shutdown. Took to dealer, read codes and it needed new dpf. still waiting for a regen cycle to see if anything comes back.
