GPF regeneration with Snap-on diagnostic testers

With the latest Snap-on Software 25.4, technicians can now perform GPF regenerations directly on a wide range of petrol models. The update enables safe regeneration of the Gasoline Particulate Filter via the diagnostic tester, including live data, pressure measurements and status checks. This prevents unnecessary replacement, maintains engine performance and ensures compliance with OEM specifications. Snap-on once again delivers a practical, workshop-ready extension for everyday diagnostic practice.

GPFs capture soot particles produced during combustion, which are then periodically removed through a process called regeneration. Understanding how GPFs work—and how they should be monitored and regenerated—is essential for accurate, efficient diagnosis.

Although GPF faults occur less frequently than with some other emission systems, clogged or overloaded filters can affect performance, activate warning lights and cause recurring faults if misdiagnosed. Thorough coverage and knowledge of regeneration procedures will ensure you can tackle these issues confidently and efficiently.
