DPF regen shows "cooling down catalyst please wait. Remaining time is 10 minutes". This happens and counts down from 10 to 9 to 8, then goes back up to 10 minutes and stays there. Waiting 20 minutes changes nothing. At the start of the regen, the app sometimes shows current dpf temperature as -64c. Does this indicate I'm missing a sensor or the temp sensor is broken or has been removed?
