Feedback about this solution from reader:
1. That is a solution but if dpf is blocked for long time this is useless unfortunately.
2. When it doesn’t work your car will go into limp mode. Then it’s time to visit the mechanic.Here is a guideo on Ford Diesel Particulate Filter (DPF) Static Regeneration Guide by specialist device.
3. This should be done regularly right from the start and not wait for the light to come on. The secret is to keep the RPMs up regularly even on local roads. Do that and you’ll never have an issue with the DPF.
4. Just did something similar with a bmw 520d drove for about 40 mins like this and the deleted the dpf code with scanner, all the power is back now, very pleased.
