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.

Thereof, what causes DPF light to come on?

The most common reason for a DPF warning light to appear is because of a blocked DPF. A failed exhaust gas recirculation (EGR) valve, problems with exhaust and injection systems and faulty glow plugs can all, in turn, affect the DPF and cause the DPF warning light to illuminate.

Furthermore, how do I know if my DPF is bad? You will know whether active regeneration is taking place by the following symptoms:

1. Engine note change.
2. Cooling fans running.
3. A slight increase in fuel consumption.
4. Increased idle speed.
5. Deactivation of automatic Stop/Start.
6. A hot, acrid smell from the exhaust.
