- Passive and active regeneration keep failing.
- A pungent smell of diesel.
- Automatic Stop-Start System Not Working.
- Your car seems to be releasing an excessive amount of smoke.

How long does a DPF clean last?
A diesel particulate filter on a poorly serviced car may fail sooner than a well maintained one, generally, they should last for at least 100,000 miles. It’s important you use the right type of oil as well – some oils contain additives that can actually block filters.
Can you drive with a full 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 don’t clean your DPF filter?
If the soot trapped by a DPF is not removed regularly, the filter can’t work properly. This results in a vast build-up of soot. When the DPF is cleaned, the excess soot is burned off. This lowers dangerous emissions and will reduce the amount of black smoke emitted by your vehicle.
How many times can you clean a DPF filter?
Generally, it’s recommended that a DPF be cleaned roughly every 150,000-200,000 miles. At this point, ash in the filter cells begins to harden. This hardening can cause the filter to crack, resulting in permanent damage.
How do I stop my DPF from clogging?
The soot can block the filter, stopping the engine from running and leaving you with a repair bill running into the thousands. To stop this from happening, the soot needs to be burned at a high enough temperature to turn it into smaller ash particles, which can then be expelled from the system.

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 many times can a DPF be cleaned?
Most DPF retrofit manufacturers recommend cleaning the Diesel Particulate Filter once per year or about every 1000 hours of engine operation. The EPA mentions that the required cleaning interval may be as short as 6 months.
How do I know if my DPF needs to be replaced?
What are the symptoms of a blocked DPF?
- Surging/poor performance.
- Excessive fuel consumption.
- Excessive smoke – white, blue, black.
- Engine and/or DPF emissions lights displayed.
- Difficult starting the engine.
- Engine runs rough.
- Unsuccessful attempts to regeneration.
How can I prevent my DPF from clogging?
Here’s our top five tips on keeping your DPF clean and trouble free.
- Drive Faster. Contrary to popular belief, driving faster could actually save you money in the long run.
- Use the right Oil.
- Get your EGR valve checked.
- Keep out of town.
- Buy the right car!
- Get clued up!

How many miles does a DPF last?
HOW LONG DOES A DPF LAST? Although, it has been estimated that a Diesel Particulate Filter should last upwards of 70,000 miles from new, many have proved to last a lot longer when properly maintained.
Does premium diesel help DPF? Not so much in the fuel system, but in the combustion area, emission components (EGR, DPF), and intake manifold, intake valves, etc. Using a premium diesel will undoubtedly delay the formation of carbon deposits in these areas.
Which diesel has least DPF problems? Every diesel had to have a DPF from January 2011. We seem to get fewest reported problems from Hyundai/KIA 1.6 CRDIs and Renault/Nissan/Mercedes 1.6 dCi 130s.
Can a blocked DPF damage turbo?
A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.
Why does my DPF keep blocking?
What causes a blocked DPF? Typical causes of a blocked DPF can include too many short journeys where the regeneration processes have not initiated. In most cases the blockage is a symptom of another problem such as faulty DPF sensor, incorrect engine oil or a failing turbo.
What problems can a blocked DPF cause?
Because a DPF blockage directly affects your exhaust system and its ability to remove gas from your engine, this then stops your engine from working as powerfully and as efficiently as it could. This in turn makes the diver heavier on the gas, which burns through fuel quicker and contributes to the engine suffocation.
Do I need to replace my DPF?
How long should a DPF last? 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 I unblock DPF?
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.
How often should you do a forced Regen?
Depending on your driving, active regeneration may happen as often as once a day. If you do a lot of stop and go, it can happen even more often. Frequency depends on duty cycle and how much soot collects – as often as once a day or every other day An active regeneration could take up to one-half hour or more.
