Caring for DPF
DPFs catch and store soot / ash and then this is burnt off under the right conditions or when an active Regen Cycle is performed by the ecu.
Passive Regen Cycle - This Regen happens all time when the dpf Exhaust gets hot enough that it passively burns the soot volume out.
Active Regen Cycle - This Regen happens when the ecu sees a set soot / ash volume measured by the pressure difference sensor and then the ECU performs an Active Cycle altering the fuelling so the engine gets to a higher temp which in turn gets the dpf to a higher temp.
Now with the colder weather over winter it’s very rare a passive Regen Cycle will happen as the dpf temp doesn’t get hot enough.
Fuel grade is important as we want to get the cleanest combustion so my advice is don’t use rubbish super market fuel (yes I know this has been debated and many claim there is no difference but facts and seeing many people have issues with supermarket fuel such as Morrison’s tells up different)
I would also advise using the ultimate grade diesel which does give a better cylinder combustion meaning a cleaner burn and running engine.
✅ Use Premium Ultimate Diesel
✅ Good long motorway Runs
✅ Use a lower Gear so the engine works harder and gets warmer (2500rpm is ideal) Motorway
✅ Get a Garage to measure the soot volume
✅ Use poor fuel
✅ Short Start / Stop Runs
