What Causes BMW Particulate Filter Blockage?

[GiaLynn]

BMW particulate filter blockage occurs due to unfavorable operating conditions for the particulate filter, preventing timely regeneration. Here are specific details about the particulate filter: 1. Resolving the particulate filter warning light: When the particulate filter warning light illuminates, it indicates the filter is blocked. For diesel models, there is a regeneration button on the center console. Pressing it will cause the vehicle to operate at high RPM for a period, after which the particulate filter will automatically clean itself. For gasoline vehicles, you can appropriately increase RPM while driving or take the vehicle on the highway to raise exhaust temperatures, burning off the particulates inside the filter, thereby resolving the warning light. 2. Impact of removing the particulate filter: All China VI gasoline vehicles are equipped with particulate filters. Removing the filter will cause the vehicle to fail annual emission inspections. Although the particulate filter may slightly reduce vehicle output, the overall impact is minimal. For diesel vehicles, the particulate filter cannot be removed either, as it plays a significant role in controlling diesel vehicle emissions.
