What may the reason for DPF regeneration lamp continuously blinking while driving?
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.
How far do you need to drive to clean DPF?
To make sure that the regeneration takes place, most manufacturers suggest that every few hundred miles, the car is driven for a period of more than 15 minutes at a consistent speed in excess of 40mph. Doing this should clear the filter.
How long can you drive with a DPF light on?
The DPF light coming on is a clear indicator that your car use and driving style needs to be reviewed, and you should avoid using the car for trips like the school run or regular journeys where the car cannot reach and maintain its normal operating temperature for at least 25 minutes.
What happens if my DPF warning light goes off?
If you continue to drive and simply hope the light will go off (which it won’t) you risk two things. Firstly the filter will become so blocked it can no longer be cleared, even by your dealer. It won’t be covered by warranty and you’ll have no change from £600+.
Can a DPF filter be changed without warranty?
It won’t be covered by warranty and you’ll have no change from £600+. Worse still the Cat/DPF will get so hot in it’s attempt to burn off the soot, it can catch fire! When the filter reaches a certain percentage full it can no longer clean itself and neither can you by driving in the correct style.
When to perform a regeneration on a DPF filter?
3. Check that the EGR system is working correctly; 4. Check that the vehicle has the correct specification engine oil; 5. Check the Eolys/Cerine additive (active system); 6. When the DPF filter load reaches a predetermined level, the ECU activates a regeneration process to increase the DPF temperature to over 550˚C.
When does the ECU activate the DPF filter?
When the DPF filter load reaches a predetermined level, the ECU activates a regeneration process to increase the DPF temperature to over 550˚C.
