We seem to get fewest reported problems from Hyundai/KIA 1.6 CRDIs and Renault/Nissan/Mercedes 1.6 dCi 130s. Our Fuel Cost Calculator shows you which will be the best choice for you. Compare the running costs of petrol, diesel and electric cars to make the right choice for you.
The early TDI engines used in the 90 and 110 series do not have DPF systems fitted.
Every diesel with a DPF has the potential for problems, however, and it all comes down to your driving style. As we said, diesels aren't suitable for just being used around town – they need longer drives too.
A DPF is vital in helping to cut pollution created by diesel engines as it traps soot from the exhaust which is then burnt into harmless ash using heat created by the vehicle's engine. All diesel cars manufactured after 2009 have one of these filters fitted, but 1,800 cars have been caught without one since 2014.

In total, 264,170 vehicles built between October 1, 2015, and April 23, 2020 were affected by the issue, across HiLux, Fortuner, and LandCruiser Prado model ranges. The defect is relevant specifically to cars fitted with either a 2.4-litre '2GD-FTV' or 2.8-litre '1GD-FTV' turbo-diesel four-cylinder engine.
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.
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.
"Maximum court-imposed penalty for an individual is $22,000!" Is a DPF delete legal? Okay, so the $22,000 question: is it legal, and can you get fined for deleting the DPF? The short answer is, yes you can get fined, and no, it's not legal.
Active 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.
Aside from increasing your risk of being charged with motoring law violations, removing your DPF and EGR can improve your car's power, performance, and fuel efficiency.
Euro 5 exhaust emissions legislation introduced in 2009 to help lower car CO2 emissions effectively made DPFs mandatory, and since then, around one in two new cars a year have been diesel-powered.
If you only ever use your car for quick trips, the DPF may not reach the temperature needed to regenerate, causing a blockage that could lead to a breakdown. So, if you drive a diesel, you should always make sure to take longer journeys every so often to keep your DPF clean and in good working order.
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 ».
Alter your driving habits
Do your research and find out how many miles you need to drive, and at what speed, to initiate the regeneration process and allow it sufficient time to complete. This will prevent any build-up of soot and particulates in the filter and extends the life-expectancy of your DPF.
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!
For on-highway vehicles, the DPF should be pulled off for its first cleaning after 150,000 to 200,000 miles, and then every 100,000 miles after that for preventive maintenance cleaning, Anderson notes.
Over time the DPF can become blocked with a residue of ash from the soot trapped in the filter being burnt off in a process called regeneration. Periodic maintenance is required to keep the DPF functioning correctly which in turn will keep the running costs of your Isuzu's low, maintaining performance and reliability.
A new Toyota DPF cost about $7,000, and this is an unnecessary expense.
Diesel Particulate Filter (DPF) manual regeneration switches are fitted as standard production features on Prado, Fortuner and HiLux vehicles from June 2018, LandCruiser 200 vehicles from August 2015, LandCruiser 70 vehicles from August 2016, Hiace from June 2016, new generation Hiace from February 2019 and Granvia ...
The easiest and cheapest method of DPF filter cleaning is by driving the vehicle for a long-distance at high revs per minute. Doing this increases the heat of the exhaust and burns the soot blocking the DPF filter. It's best to drive on a motorway or A road where you can keep the vehicle at a consistent speed.
Most DPFs will automatically clear as they're used but on rare occasions, in specific circumstances, they may get blocked and require manual cleaning. In normal use, a DPF cleans or regenerates itself by reaching a sufficient temperature to burn off the excess soot.
Act immediately or your only option will be to take the car to a garage for repair. There are no additives or methods that will clean a BLOCKED DPF. There is a narrow window where a mechanic can clean the DPF by forcing a regeneration but after this narrow window your only option is to fit a new filter to your car.
