What do I do if my DPF light comes on?
When the DPF light has become illuminated, it’s telling you that ‘passive regeneration’ has failed and that you need to actively regenerate the diesel particulate filter. You can do this by increasing your speed to more than 40mph for between 10 and 15 minutes.
What does it mean when the DPF light is flashing?
A flashing orange DPF light (or whatever the primary activation mode is) just tells you that the filter is getting loaded up, and a burn or regeneration is necessary and/or overdue. The car knows this because it measures the pressure drop across the DPF. If the light goes out, it worked.
How do I fix my diesel particulate filter warning?
If you get a warning light showing that the filter’s blocked, it should be possible to complete an active regeneration cycle and clear the warning light by driving for 10 minutes or so at speeds over 40mph.
What will you do if the diesel fuel particulate and engine warning lights come on?
When this light first comes on, continue driving your car like normal and try the active regeneration method by driving on the highway. This should turn off the light as long as nothing is preventing the regeneration from taking place.
How do you tell if your DPF is clogged?

How do I clear a blocked DPF?

How do you know if your DPF is regenerating?
You will know whether active regeneration is taking place by the following symptoms:
- Engine note change.
- Cooling fans running.
- A slight increase in fuel consumption.
- Increased idle speed.
- Deactivation of automatic Stop/Start.
- A hot, acrid smell from the exhaust.

Why does my DPF warning light come on?
How it works and why the light may come on. The Diesel Particulate Filter (DPF) is part of your exhaust and controls the ‘soot’ that would otherwise be expelled from the system.
What are the symptoms of a block DPF filter?
Symptoms of a Block DPF Filter. As the majority of DPF’s are installed on newer cars, you will more than likely have a trip computer. Error codes such as the DPF light or EML (Engine Management Light) will be the first symptoms of a failing DPF.
What should I do if my DPF is not working?
1. Check pressure sensors as there could be a build up of water; 2. Examine pressure pipes for damage. They must be clean or they could freeze in extreme temperatures due to water build up; 3. Check that the EGR system is working correctly; 4. Check that the vehicle has the correct specification engine oil; 5.
What’s the best time to reset your DPF light?
You should drive your vehicle for approximately 15 minutes keeping the engine revs between 2000 – 2500 rpm. This is probably best done on an A road. Keep the car in a lower than normal gear (use ‘S’ on an automatic) in order to keep the revs up.
