Diesel ignites under extreme heat, after its burn it leaves behind a soot which is captured by the DPF. Once the soot levels reach a preset threshold, the computer will initiate DPF burn, you’ll sometimes notice this with a bit extra power and the idle higher than normal at idle.
If the DPF clean/burn procedure is interrupted, it will try again at your next drive. After several failed DPF clean attempts, the vehicle will go into limp mode and you will need to initiate a DPF burn manually.
