Hi guys,
Just been travelling a bit pulling a caravan and also not. Notice the the following DPF behaviour,
1. If you sit idle for too long the DPF stops the burning process until moving again.
2. If travelling with a caravan a burn occurs about every 200km and lasts a whopping 60 to 70km.
3. When a burn is occuring during the tow period the DPF will go all the way back to zero percentage full, whereas city driving with a little freeway usually gets down to about 6% full before finishing.
4. Travelling at 110km/h causes the DPF to burn less efficiently due to what I can only say is a reduced DPF temp around the 500 deg mark. When driving at slower speeds the DPF gets up to the mid to high 600 deg. When towing it seems to do the best burn go figure.
Hope this helps clarify some of the mysteries of the DPF burn cycle.
