What is a Particulate Filter?

[DeBrayden]

A particulate filter is a ceramic filter installed in the diesel engine emission system, which captures particulate emissions before they enter the atmosphere. To comply with domestic environmental emission standards, Volkswagen has equipped many of its models with particulate filters. Examples include the Tayron, Tiguan L, and Sagitar. However, depending on the vehicle's power configuration and factory settings, not every car is equipped with a particulate filter. You can check whether a vehicle has a particulate filter using the following three methods: Check the and to see if there is a particulate filter function. Additionally, carefully review the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates that a particulate filter is installed. Look behind the three-way catalytic converter on the exhaust pipe to see if there is an additional cylindrical section. If present, that is the particulate filter.
