EU investigating diesel collusion among Audi, BMW, Mercedes, Porsche, VW:  report

DPF stands for diesel particulate filter. It is a component of a diesel emission control system that uses a combination of a fabric filter and regenerating thermal oxidizer to remove particulates from the exhaust stream. DPFs are used on modern diesel engines to meet increasingly stringent emission limits. They have been shown to significantly reduce the concentration of particulate matter in the exhaust gas, thus delivering significant health benefits to those inhaling it. Unfortunately, DPFs may fail prematurely because they require diligent maintenance and care, which many drivers neglect to do so. Left unchecked, this can lead to expensive problems with Dpf delete regeneration and premature replacement of the entire system. This article will teach you how you can effectively clean your DPF yourself, saving money

DPF Basics

The relatively inexpensive fabric filter is what captures and removes small particles from the exhaust gas, while the thermal oxidizer captures the chemically reactive particles before they combust. The regenerating thermal oxidizer material generally consists of methanol, with some formulations containing sulfuric acid. A combination of all three components is typically used to remove pollutants. DFRP Control Valve The DFRP control valve (Diesel Particulate Filter Overflow Protection Valve, or D-RPOV) is mounted inside the DPF box and enables the D-RPOV material to capture the particulate matter in the exhaust. When a DPF is completely clogged, the D-RPOV fails, and you need to replace the entire Dpf delete.

How to Delete DPF on a VW, Audi, Porsche or BMW

There are many different ways to clean your DPF, but if you want to be sure your system is clean, let’s get straight down to business. In this step-by-step guide, we will go over the steps involved in properly cleaning your DPF, including cleaning equipment, methods, and parts, and best practices. Step 1: Power down To properly clean your DPF, it is necessary to shut it down. This means turning off the engine and using the key to lock it. Turn the key completely to “off,” then gently lift the key. If you are in a vehicle without a key start, twist the key clockwise while pushing the clutch down. The engine should be completely off when the DPF cover is removed. Step 2: Remove filter and mounting Remove the DPF filter.

Why the DPF Failed

The DPF has two components: The container (containing the fabric filter) The regenerator (using thermal oxidizer to heat it up and clean the filter) DPFs can fail because of a number of reasons, including: Poor maintenance: Often, when the DPF was manufactured, the fabric filter and/or thermal oxidizer was not designed to have to be changed when worn out. This can leave the filter with holes, which causes clogging. Often, when the DPF was manufactured, the fabric filter and/or thermal oxidizer was not designed to have to be changed when worn out. This can leave the filter with holes, which causes clogging. Damage from improper use: Your car can quickly overheat and require a DPF to be replaced.

What Can You Do?

For this article, we will focus on how to remove DPF by removing all of its parts using a set of aftermarket shop tools. The key to removing the filter is to be precise with your procedure and aggressive with the cleaning process. You will need a set of shop tools, a diesel filter, and some basic knowledge of how the different parts work together. Before we begin, here are some items you will need: 1. Volkswagen DPF A diesel particulate filter (Dpf delete) is the third stage of diesel emission control in a diesel engine. An important part of the engine control unit (ECU), it cleans the air passing through the engine, removes all particles, including emissions, from the exhaust stream, and stores the clean air in a chamber to be used to optimize combustion and increase fuel efficiency.


Many people don’t know how to properly clean a Dpf delete. These devices are a great health benefit but need a lot of care, especially with the proper cleaning. After reading this article, you will have the knowledge you need to clean a DPF and have fewer issues down the line. Are you planning on buying a new car soon? Do you own a used car?
