You feel a loss of power in your engine (limp mode). The DPF light will appear on your dashboard. Passive and active regeneration keep failing. A pungent smell of diesel.
A blocked DPF filter can cause problems, which is why you need to make sure that it is clean. If it's too late and you're noticing a strong diesel smell, excess amount of smoke, regen failure, and most commonly the DPF light on your dashboard. If that's the case your filter may require replacement or physical cleaning.
If your DPF is blocked, your engine will have to work harder to expel exhaust gases, reducing available power and increasing fuel consumption. To bring your engine efficiency back to normal levels, you will need to clean your DPF filter, so consider DPF cleaning in the UK if you notice any of these symptoms.
Sometimes, a hot and pungent smell can also start coming from your engine as the soot is being burned away. Your stop / start function may also deactivate. Driving for 15 minutes as speeds above 40mph should provide your DPF filter with enough heat to burn away the soot by itself.
It's not impossible to clean a DPF at home. But the risk is high. The filter is a very delicate component of your car. You can easily damage it during DIY cleaning.
A blocked DPF or obstructed exhaust will force your engine to work harder to expel exhaust gases, reducing available power and increasing fuel consumption.
DPF deletion does not affect vehicles' engine performance, power generation and horsepower. It can improve performance by freeing up space in the engine bay and reducing weight. However, there are some potential drawbacks to consider before going ahead with a DPF delete.
clean it! A diesel particulate filter is a device that traps unburned carbon particles, commonly known as fine particulate matter. These pollutants are produced during normal engine operation and the role of the particulate filter is to clean them out.
DPF's are in fact designed to last in excess of 100,000 miles but if the vehicle is operated correctly, many will far exceed this mileage. Below are a few simple steps you can take to ensure you achieve the maximum lifespan from yours.
How Long Should A Diesel Particulate Filter 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.
The most common reasons for DPF blockages are: Short journeys where the engine doesn't reach optimum operating temperature; Clogged EGR Valve increasing diesel soot passed to the DPF; Faulty fuel injectors sending too much fuel to the air/fuel mixture; Incorrect engine oil upon servicing the car ; Turbocharger failure ...
Once blocked though, turbo failure can occur very quickly. If you don't check for a DPF issue when installing a replacement turbo, there is a very high chance the replacement turbo will suffer the same failure, as it will be subject to the same operating environment as the previous unit.
While your vehicle won't stop running the moment the light turns on, continuous driving can lead to more severe issues like decreased fuel efficiency, reduced performance, and in the worst case, engine damage. An illuminated DPF light will cause an MOT failure.
Removing the DPF from your car is an illegal operation that can cost you dearly. The article L. 318-3 of the highway Code prohibits very explicitly since 2014 to « remove a pollution control device ».
A diesel particulate filter check has been part of the MOT test since February 2014. If a filter has been removed, the car will fail its MOT. Removing the DPF will sometimes cause the warning light to glow – and this itself is an MOT failure point: no dashboard warning lights should remain on during the test.
How to unblock a DPF? 1) DPF Regeneration - Find a motorway near you where you can drive at 70+ MPH for 30-45 minutes; this should provide the optimal conditions for the regeneration process to complete. If this works, consider a regular drive along a motorway regularly to allow the regeneration process to complete.
DPF cleaning involves the use of aqueous cleaning technology and specialist chemicals to reduce the soot emissions generated by your engine. Usually, your DPF removes soot automatically using passive regeneration. Our cleaning service removes the excess soot that is preventing regeneration from taking place.
Drilling holes in substrates of diesel particulate filters to make exhaust gases flow more freely through the honeycomb structures. This defeats the purpose of the DPF, which is to remove soot from the exhaust, and affects reliability of the devices, noted Kevin Otto, service director for Cummins Emissions Solutions.
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.
