Can I clean a DPF myself?
Don’t DPFs clean themselves.
In theory, yes.
“Passive Regeneration” or if appropriate Active DPF regeneration will take place as part of a healthy diesel engine running cycle, but active regeneration can fail once a blockage reaches a certain level.
Sometimes a “forced” regeneration may be carried out by a mechanic..
Is it OK to drive with DPF light on?
Can you ignore the DPF light and carry on driving? Technically yes, but we would not recommend it. If you ignore the DPF light and continue driving, the build-up of soot will soon reach a point whereby your car has to enter ‘limp-home’ mode in order to prevent any damage to the engine.
How do you know when 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 is my DPF not regenerating?
The DPF will not regenerate if: The engine management light is on for any fault; There is a faulty EGR valve; There is less than 20 litres of fuel in the fuel tank, if the fuel light is on or the engine management light is illuminated.
How often does a DPF regenerate?
every 300 milesActive regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete. But it’s a problem if your journey’s too short and the regeneration doesn’t finish.
How long does it take to do a parked regeneration?
How long does a parked regeneration take? It takes approximately 20-60+ minutes. It will continue to regen until the soot level has reached ‘low’ or ‘0%. ‘ Some trucks will let you monitor your soot level gauge on the dashboard.
How do you clean the DPF on a motorway?
Warm up the engine to operating temperature, then drive it for 15 minutes at constant speed on a motorway. Aim to keep the revs above 2000rpm for this period. The heat generated will help clean the DPF filter and the cars Regeneration cycle will usually kick in under these circumstances.

How far do I 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.
Does DPF Cleaner Work?
Yes, you can use Redex DPF Cleaner to prevent problems as well as cure them. … However, it’s not a very reliable way to keep the DPF working. Redex DPF Cleaner is much easier as it lowers the temperature that the soot burns at, so it will burn off during normal driving.
Can you drive during a regen?
Usually, nothing. The vehicle needs to run at operating temperature during the regeneration, so highway driving is best. Just drive as you normally would. During active regeneration, the exhaust outlet temperature is extremely high.
How long does a DPF last?
around 100,000 milesA DPF can last up to around 100,000 miles if maintained properly. After the car has exceeded that mileage, you could be looking at paying a large amount of money for a replacement – so always properly check MoT and service records when buying a used car.
Can a blocked DPF damage the engine?
Driving the vehicle with a blocked DPF can seriously damage your engine / turbo and it’s not uncommon to have to replace a turbo when the warning light has been ignored for extended periods. The ash residue which remains after successful regeneration cannot be removed and will eventually fill the filter.
