It will suffice if it was constructed after 2009. Since September 2009, all diesel cars have been required to include a DPF in the exhaust system to prevent soot from entering the atmosphere. It’s part of the Euro 5 diesel standard, but some vehicles constructed before that date include DPFs as well.
Which car has least DPF problems?
Hyundai/KIA 1.6 CRDIs and Renault/Nissan/Mercedes 1.6 dCi 130s appear to have the fewest reported difficulties. Our Fuel Cost Calculator will show you which option is best for you. To make the best decision, compare the operating costs of gasoline, diesel, and electric vehicles.
Do all diesels have DPF issues?
Are DPF filters standard on all diesel vehicles? A DPF is standard on all new diesels. DPFs became necessary in 2009, however a few earlier diesels will be equipped with them as well. If your diesel engine is pouring soot out the back, it doesn’t have a DPF.
Which cars have the most DPF problems?
The most often asked issue appears to be which current diesel vehicles are most vulnerable to DPF clogs and breakdowns.
Unfortunately, there is no clear answer for us, but see below for a list of cars that have come up most frequently in both comments on our website and through our Twitter account.
DPF filters are not covered by warranty, and there is no way to rapidly determine a car’s DPF history, so buyer beware. If you’re concerned about this, talk to your salesman about having the DPF covered for a limited time after you pick up your new vehicle.
The most important piece of advise we can give is to take your time while shopping for a new car. In and of themselves, the headline MPG figures and low tax might make a compelling case. Make sure a diesel car is right for you by doing your research. Also, keep in mind that our DPF cleaning and DPF FAQ pages may be able to save you money on repairs and DPF regenerations.
It’s also a good idea to have your EGR valve inspected. Excess diesel particulates can be created by faulty or failed units, leading the DPF filter to clog up faster. Due to residue and carbon buildup around the valve and EGR housing, this appears to affect older automobiles more. For additional information on EGR valves, see our EGR valve FAQ page.
Should I get my DPF removed?
According to recent data, tens of thousands of drivers have been discovered driving without their diesel particulate filter. Since 2014, the Driver and Vehicle Standards Agency has discovered 1,800 drivers driving without a pollution-reduction filter in their vehicle.
While it is not against the law to remove a car’s DPF, it is against the law to drive without one if one is required. It’s thought that some drivers who have DPFs that have gotten blocked are just removing them rather than paying for a replacement, which may cost up to £1,000. Car drivers risk a £1,000 punishment, while driving a vehicle without a DPF carries a £2,500 penalty.
Diesel particulate filters collect small pollutants from diesel engines that would otherwise be released into the atmosphere. They do, however, require’regeneration,’ which requires burning off the collected particles on a regular basis. High temperatures, which are normally reached when a vehicle is driven at a reasonably high speed, are required for this process to occur. Diesel drivers who mostly drive in cities may experience blocked DPFs since their vehicles do not routinely achieve the conditions required for regeneration.
The removal of a DPF is a very straightforward procedure that involves cutting a hole in a vehicle’s exhaust, removing the filter, and welding the hole closed. Although diesel cars must have a DPF to pass MoT inspections, this is only assessed visually rather than through emissions testing. Removing the filter has no effect on the car’s performance, and some drivers claim that driving without one improves fuel economy and engine performance.
We are regularly questioned whether premium diesel fuel is superior to standard diesel fuel in the course of our business. And our quick response is invariably a loud yes “Yes,” says the speaker. However, additional information is needed to answer the other major concern about premium diesel fuel, which is whether it is worth the extra price.
Premium diesel has more detergent and additives than regular diesel, which helps to improve the combustion performance of an engine. Using a premium diesel usually results in a gain in performance and/or MPG, as well as lower engine emissions and other benefits, depending on engine design.
Yes, premium diesel is superior to regular diesel. Is the extra price tag, however, justified?
We are not so sure about it. The fundamental issue is that, given the huge increase in cost per litre, premium diesel fuels might be so much better. The additional detergent now offered is insufficient to keep most gasoline systems and engine types clean, and it does not aggressively remove existing deposits. Unfortunately, we’ve discovered that diesel vehicles that only run on premium diesel fuel continue to deposit. Not so much in the fuel system as much as in the combustion region, emission components (EGR, DPF), and intake manifolds, intake valves, and other areas. Using a premium diesel in these places will surely postpone the accumulation of carbon deposits. However, don’t expect miracles in terms of cleaning results. Fuel system pollution, biological degradation, and carbon build-up rise as the percentage of bio-diesel increases. Regrettably, current fuels are insufficient to meet these concerns.
Please keep in mind that there are legal constraints, such as the old BS EN590 specification, that limit the types of additives that can be used in fuel. Those rules, however, have no bearing on whether premium diesel, as it is manufactured now, is a fair value for the money you spend at the pump.
So, what should you do if premium diesel isn’t worth the extra money and normal diesel isn’t up to par? To ordinary diesel fuel, we recommend adding a high-quality diesel fuel conditioner with combustion catalyst technology. This will often result in a fuel that outperforms premium diesel while also being less expensive per tank. This is supported by extensive testimony as well as research evidence. More comprehensive fuel conditioners include technology to clean and remove existing deposits, lubricate the diesel pump, remove water, prevent fuel degradation or contamination, reduce emissions, improve performance, and increase MPG, among other things.
It’s simply a matter of evaluating the advantages of premium diesel against the advantages of a fuel conditioner, as well as convenience and expense.
In this topic, there is also the matter of consistency to consider. It’s not uncommon to find fuel of varying grade from the same gas station. According to our understanding, fuel merchants and refineries have distribution agreements in place that require gas stations to sell fuel from the nearest refinery in the area, regardless of brand. The additive packets are then applied at the refinery or directly into the station gasoline tanks in some cases.
Similarly, there is a difference in the price of gasoline. Octane testing on a regular basis will reveal remarkable discrepancies in fuel octane. It tests at 95.6 one week, 96.8 the next, and so on. As you may expect, this makes testing octane boosters exceedingly difficult due to the inconsistency of base fuels.
A piece of advise we’d like to provide is to “Know” your local gas station. Purchase fuel at stations with a high turnover of fuel whenever possible. Avoid filling your car from tanks that are low on fuel or that have recently been filled, since this can cause deposits and moisture to settle. Come return later if you spot a tanker. The inherent faults and irregularities found in our fuels should be protected by a fuel conditioner.
Please note that we will be producing a video in the future illustrating one of the tests we do to determine the cleaning strength of fuels and fuel additives.
Can a blocked DPF damage the engine?
Driving with a blocked DPF can cause major damage to your engine / turbo, and it’s not rare to have to replace a turbo when the warning light is ignored for an extended period of time. After successful regeneration, the ash residue that remains cannot be removed and will eventually fill the filter.
How do I stop my DPF from clogging?
Driving faster, contrary to popular thought, may actually save you money in the long run. DPF regeneration is only possible when particular circumstances, such as engine speed, RPM, and temperature, are met. The DPF regeneration process will not begin unless all of the prerequisites are met, and you’ll be one step closer to a pricey dealer regen (trust me I know from experience).
Do your studies and figure out how quickly, for how long, and at what RPM you need to drive. If your dealer refuses to provide you with this information, we propose contacting the internet community and owners clubs.
How can I tell if my car has a DPF?
First and foremost, you should be aware that the DPF is a component of the exhaust system. The exhaust pipe is located between the silencer and the catalytic converter. The DPF is located in the catalytic converter in some car models.
Run your finger around the interior of the pipe to see if it’s clogged. You can presume your automobile has DPF if it is relatively clean.
Does AdBlue stop DPF problems?
As the gases flow through the filter, the soot trapped in the DPF begins to clog the filter. This system, however, is not a replacement for a DPF, as automobiles with AdBlue tanks will always have a DPF as part of the overall emissions control system.
