This guide shows how to run a forced particulate filter regeneration on a VW Passat B7 wagon through the OBD2 port, including what to do when the tool reports no DTCs and how to handle a regen that cancels mid cycle.

Step-by-step procedure
Open the guided regeneration function
Connect the Autel IM608 Pro 2 and navigate to Volkswagen > Automatic selection > Pre-Scan > 01 Engine Control Module 1 > Guided functions > 01 Particle filter service regeneration.
The tool runs two things under this function: it checks the event memory for regeneration-hindering entries, then runs the service regeneration itself.
Confirm the transmission and parking brake
The tool then asks two confirmation questions directly: is the manual gear in neutral, and is the selector lever in position P for automatic cars. Confirm the one that applies to your transmission.
Next it asks to confirm the parking brake is set. Answer Yes.
Read the safety instructions
A safety instructions screen follows. It warns that exhaust temperature at the tailpipe can reach up to 300°C during emergency regeneration, with a duration up to 40 minutes. It also asks you to check whether an exhaust extraction system can be connected, or to run the test in an open area if not.
Check the event memory
The tool checks the engine control module for entries that block a regeneration and asks whether to end the test.
Run the regeneration
Once confirmed, the car raises engine RPM on its own to build exhaust temperature. The dash shows guided prompts through the process, and the tool logs live temperature readings before the turbocharger and before the DPF, along with a countdown timer and a running regeneration status.
