Diesel Particulate Filter: What Diesel Car Owners Need To Know about it

Introduced by vehicle makers to minimise exhaust emissions in diesel cars – Diesel Particulate Filter (DPF) is somewhat of an ‘alien’ to most people. Back in 2009, a law passed in the UK mandating the installation of DPF in diesel cars to reduce carbon dioxide emissions in the country. It’s a vital step from the Department for Transport to keep harmful emission under the legal limit.

DPF Dissected

Diesel Particulate Filter traps soot particles formed from a diesel engine, preventing them from being pumped into the atmosphere. However, like any other filters, DPF also gets clogged from the constant accumulation of soot. Therefore, it needs a thorough cleaning to function properly.

DPF Regeneration

Though it sounds like a mutant with regenerative abilities, Diesel Particulate Filter isn’t as mutant-ish as you think!

It’s rather simple. As soot gets trapped within the filter, it needs to be eliminated by burning off or by emptying. This is basically DPF regeneration as it cleans itself. Now, this regenerative ability falls under two categories –

  • Passive

  • Active

Passive Regeneration

It happens when you rev up your car’s engine. Driving for 10-15 minutes at high-speeds every once in a while makes a DPF regenerate itself. This ability to ‘clean itself’ prevents soot build-up. It is possible in cities where a car is used frequently but only for short distances.

However, driving consistently on a motorway doesn’t allow a passive generation to occur. Which bring us to…

Active Regeneration

In this case, your vehicle’s computer raises the temperature of exhaust fumes. This kick starts a regeneration process which usually lasts for 5-10 minutes. Most modern diesel cars are equipped with this feature, but sometimes this system malfunctions. Under such circumstances, you must take your diesel vehicle to a local garage for professional DPF clean-up.

What If You See The Dpf Warning Light?

DO NOT panic!

If the warning lamp turns on, it’s time to take your vehicle for a longer run. Hit the motorway and drive at 40-50mph for 10-15 minutes and you’re good to go!

By now, you must be wondering “Why don’t I just get rid of this DPF?

DON’T. Just don’t.

Is Getting Rid Of Dpf A Good Idea?

Though it might look like a permanent measure for all your woes, getting rid of DPF means more trouble.

Firstly, Diesel Particulate Filter cuts down harmful emissions – hence it’s fitted for a purpose. Secondly, you can’t drive for long without a DPF. As per new rules of MOT, any alterations of the DPF will render your car un-roadworthy. If the technicians spot you’ve removed the DPF, you’re in deep trouble.

Therefore, it’s mandatory to keep your DPF in its place. However, you can schedule a DPF clean-up at any local garage. Numerous licensed garages perform DPF cleaning in Northampton.
