Audi Diesel Particulate Filter (DPF) - Genuine Audi 4H0254750HX

Product Information

Your vehicles diesel particulate filter, also known as DPF, is responsible for removing soot and particulates from the exhaust. On diesel vehicles the combustion process is "dirtier" than conventional gasoline powered engines. Due to environmental regulations all modern diesel engines are equipped with a DPF system. Some modern vehicles have the ability to clean out the filter using a process called active regeneration which essentially burns off the soot and debris that builds up inside the filter. In some cases, active regeneration cannot clean the filter adequately enough which can cause an array of performance issues. If this occurs you will get a CEL warning on your instrument cluster with codes associated to a failed or blocked DPF.

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Audi parts box and find an OEM branded part inside, simply with the addition of an Audi logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
