Do I need a diesel particulate filter?

Diesels produce lots of soot (particulate matter) that can cause respiratory problems and contribute to the risk of cardiovascular diseases. Modern diesel cars (since 2009) have to be fitted with a Diesel Particulate Filter (DPF) in the exhaust to stop this soot passing into the atmosphere.

Do particulate filters work diesel?

The cleaner works by reducing the combustion temperature of the soot particles. This means that the exhaust does not have to be quite so hot in order to burn off the particles which have gathered in the Diesel Particulate Filter.

How long should a diesel particulate filter last?

100,000 miles
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.

How often do you change a diesel particulate filter?

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.

How often does a diesel particulate filter need cleaning?

roughly every 150,000-200,000 miles
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 long will a diesel particulate filter last?

How much does a diesel particulate filter cost?

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!

What is the cost of a DPF filter?

Where is the particulate filter located on a diesel engine?

The diesel particulate filter (DPF) is part of the exhaust system in your diesel vehicle. You can find the filter sitting ahead of the NOx trap, otherwise known as the NOx storage catalytic converter. You will often find the DPF filter close to the exhaust manifold.

How do I know if my diesel particulate filter is bad?

The first common sign of a bad DPF is a check engine light on your dashboard. The diesel particulate filter uses sensors to measure the pressure and temperature before and after the DPF filter. If the pressure is not correct, the engine control module will light up the check engine light on your dashboard.

What happens if the DPF filter is clogged?

When the DPF filter gets blocked or clogged, the engine becomes weaker and a check engine light often shows on your dashboard. It can also lead to higher fuel consumption and create a hard-starting situation. Additionally, you may also notice strange smells or turbocharger issues.
