What do you do if your particulate filter light comes on?

When you first see the light, you can resume normal driving, but when you get a chance, take the car onto the highway and drive it for around 10 minutes at 40+ MPH. This should sufficiently raise the temperature to levels high enough to regenerate the filter, and hopefully the light will turn off.

Why does my diesel particulate filter light keep coming on?

The most common reason for a DPF warning light to appear is because of a blocked DPF. A failed exhaust gas recirculation (EGR) valve, problems with exhaust and injection systems and faulty glow plugs can all, in turn, affect the DPF and cause the DPF warning light to illuminate.

What is particulate filter on VW Golf?

The diesel particulate filter filters out soot particles in the exhaust gas. The soot particles gather in the filter and are burnt under high temperatures periodically (regeneration).

How much does it cost to have a DPF filter clean?

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 does the VW Golf have a diesel particulate filter?

To keep emissions inline with EU regulations VW had no choice but to fit the Golf with a diesel particulate filter (DPF for short). The introduction of the first 2.0l diesel into the Golf saw the first DPF strapped to a Golf exhaust.

What does the diesel particulate filter warning light mean?

What Does the Diesel Particulate Filter Warning Light Mean? The diesel particulate filter light turns on when the soot level from the diesel exhaust is high and your car is at risk of going into limp mode. In order to combat exhaust emissions, modern diesel engines are fitted with a particulate filter in the exhaust.

What does the DPF light mean on a diesel?

How to reset/regenerate/clear your DPF warning light (Diesel Particulate Filter) The Diesel Particulate Filter (DPF) is part of your exhaust and controls the ‘soot’ that would otherwise be expelled from the system. You may have noticed that modern diesels no longer leave you in a cloud of smelly black smoke when they accelerate off.

What happened to the DPF on golf diesels?

From the mighty Mk1 all the way up to the dull Mk4 (yuk!), Golf diesels escaped the impending doom of the DPF. Euro 5 emission regulations were introduced in 2005, so too was the need for something to stop carcinogenic diesel particulates from spewing out of Golf exhausts across Europe.
