A diesel particulate filter, or DPF, is an exhaust aftertreatment device that traps particulate matter such as soot and ash. Engine manufacturers use DPFs to trap particulate matter in order to meet the EPA 2007 emission standards.
What is a DPF on a diesel engine?
Definition. Diesel particulate filters (DPF) are devices that physically capture diesel particulates to prevent their release to the atmosphere. Diesel particulate filter materials have been developed that show impressive filtration efficiencies, in excess of 90%, as well as good mechanical and thermal durability.
What happens when your DPF fails?
Under certain conditions, a DPF can become blocked, causing an engine fault code to display. Ignoring a DPF warning light can result in loss of power, reduced fuel economy, poor throttle response and difficulty starting & from 25th May 2018 is an MOT failure.
What is a DPF part?
A diesel particulate filter, or DPF, is an exhaust aftertreatment device that traps particulate matter such as soot and ash. A DPF typically uses a substrate made of a ceramic material that is formed into a honeycomb structure.
How often does DPF need replacing?
A 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.
How do you clear a blocked DPF filter?
- Passive regeneration: This happens naturally when the car gets hot enough, during long drives at a high speed.
- Active regeneration: This is a process that your car can initiate in response to a blockage.
What does deleting the DPF do?
A DPF delete removes a vehicle's DPF and configures the computer system to function without it. The exhaust is used to physically replace the DPF, while the tuner disables the vehicle's regeneration mode and ensures that no other engine codes come up.

Can a blocked DPF be cleaned?
When a diesel particulate filter is clogged, in most cases you can solve this relatively easily and cheaply by driving the DPF clean. The car normally does this automatically when there is a long drive, but many cars need a little extra help.
Is a DPF expensive to replace?
Replacing a DPF can easily cost $4000 to $8000, and sometimes more, it's a big cost… particularly when a vehicle is out of warranty!
How do I get my DPF to regenerate?
Driving at 70mph or above for a while will heat the exhaust enough to burn off the soot particles which have been trapped by the DPF. But most drivers to not drive at high speeds often enough or for enough time to rely on this passive regeneration to clear the DPF of soot particles.
Can I drive with a faulty DPF?
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.
What happens if you dont fix DPF?
While it is technically possible, and the car would continue to run as normal, a missing DPF filter will result in an automatic MOT failure, and could invalidate the car's warranty, leading to more expensive repair bills.
What are the symptoms of DPF failure?
- Poor engine performance.
- Poor fuel economy.
- High engine temperatures.
- High transmission temperatures.
- An increase in black smoke (soot) from the exhaust.
- Check engine light.
