What does the diesel exhaust filter do?

A diesel particulate filter, or DPF, is an exhaust aftertreatment device that traps particulate matter such as soot and ash.

How long do DPF filters last?

around 100,000 miles
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.

What is a filter exhaust?

Exhaust filters are used to remove impurities from air drawn through a ventilator in a closed system. Exhaust filters are an essential component of industrial air pollution or emission control systems and are often far more complex than commercial and residential filters.

How often do DPF filters need to be replaced?

On average, a DPF filter needs to be cleaned every 200,000 kilometers, or around 124,000 miles. However, any specific filter may get clogged or blocked sooner than that, especially if the truck is on the highway less often than average, and spends more time running at lower speeds.

Is it illegal to remove DPF?

While it’s not illegal to remove a car’s DPF, it is illegal to drive without it if one should be fitted. Removing the filter doesn’t affect the car’s performance, and some motorists even state they achieve better fuel economy and engine performance without one.

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 you clear a diesel particulate filter?

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 much does a DPF filter clean cost?

Cold starts also create the need for more frequent DPF cleanings, which shorten DPF effectiveness and, ultimately, lifespan. Factor in downtime for cleaning DPFs and replacement costs can range between $2,500 to $8,000 per vehicle.

Why are DPF so expensive?

Why are they so expensive? The DPF is a large section of the exhaust system, unlike the air, oil, fuel or pollen filters, is not intended to be replaced easily, it needs to be done by a professional with diagnostic tools, to ensure the ECU knows it has been replaced.

How often should I Change my diesel fuel filter?

You must change your vehicle’s fuel filter at 50,000 miles. Subsequent filters should also be changed at least every 50,000 miles, but changing them annually is even better. This is especially true once the car is at least seven years old, because rust, debris and other contamination builds up in the fuel tank and can clog the filter faster.

What is DPF delete?

DPF Delete. It also helps to cool the engine down and lower the exhaust gas temperatures. One of the best features though; is the fact that the water methanol is injected into the intake elbow or manifold which cleans any old EGR soot out of the engine. It also keeps the intake clean for the lifespan of the truck.

What is DPF system?
