DPF Regen Myths Busted: What Really Keeps the Filter Clean
The Truth About Regeneration
A Diesel Particulate Filter (DPF) burns soot into ash at 550 °C +.
Hit that temp, soot clears; fail, and you’ll soon see the dreaded P242F or “DPF Full” light.
Below we bust five common myths that cost van owners time, fuel and money.
Myth 1 – “Rev It on the Drive for 20 Minutes”
| Fact | Why It’s Wrong |
|---|---|
| ECU triggers regen only above 40 km/h for ≥ 15 min | Idling never hits 550 °C; you’re just wasting diesel |
Myth 2 – “Add This £10 Bottle to Your Tank”
| Fact | Why It’s Misleading |
|---|---|
| Additives can lower soot burn temp by 20–30 °C, not 200 °C | Still need sustained load and the right EGTs |
Myth 3 – “Force Regen Every Month Just in Case”
| Reality | Risk |
|---|---|
| Each regen adds ash, the non-burnable residue | Excessive ash = £250 ultrasonic clean sooner |

1 · Diesel Knock at Idle
A metallic tap that disappears above 1 500 rpm often means one injector over-fuelling.
