How Long Can I Drive My VW with DPF Light On? There is no straightforward way to answer a question like this. But, one thing's for sure—seeing a warning indicator like this one on your car's dashboard can be an intimidating experience, especially if you're not sure what it means. There are some interesting facts about DPF light in this article, including what it means, why you see it and how can you fix it. So, please go through it. Let us begin with discussing what 'DPF' means.
What Is DPF And What Does It Stand For? First off, DPF is the abbreviation for Diesel Particulate Filter. Its end goal is to capture particulate matter or soot present in the exhaust gas generated by a diesel engine. For those who don't know, the diesel engine (or, compression-ignition engine) is a kind of internal combustion engine that works on the principle of the Otto cycle to generate motion from chemical energy. And, guess what... it produces a lot of pollutants in the process- which if not removed from the exhaust gas, can harm the environment. In order to deal with these pollutants, almost all vehicles powered by diesel engines come equipped with after-treatment systems. The diesel particulate filter (DPF) is an important part of a diesel vehicle's after-treatment system. Some of the other major components arediesel exhausts fluid (DEF) and selective catalytic reducer (SCR). Now that you know what a DPF is and what it does, let’s discuss the reasons why DPF light may come on and what you can do about it.

Particulate filter- It’s probably clogged The simplest explanation is usually the best one. The particulate filter, as most of you probably know by now, is an important part of a diesel vehicle’s after-treatment system. DPF reduces the toxicity of exhaust emissions by trapping the particulate matter produced due to the combustion of diesel in the combustion chamber of the engine. However, it can clog over time due to soot accumulation. And, a clogged DPF is of no use. Also, the DPF - when jammed, can make it hard for the engine to breathe. When the onboard computer encounters this problem, it will activate the DPF warning light to alert the driver.
