How to Force DPF Regeneration on VW Touran 2016 1.6/2.0 TDI EU6 (Type 5T)

This guide shows how to perform a forced DPF (Diesel Particulate Filter) regeneration on the VW Touran 2016 1.6/2.0 TDI EU6 through the Engine Control Module hot functions.

Forced regeneration burns off accumulated soot when passive or active regeneration hasn’t completed typically triggered by DPF warning light, limp mode, or high soot mass readings.

Technical overview

Item	Details
Vehicle	VW Touran (Type 5T) 1.6 TDI EU6
Year	2016
System	Engine Control Module 1 (Address 01)
Procedure type	Service regeneration, particle filter (hot function)
Difficulty	Medium
Time required	~20-60 minutes
Prerequisites	Battery > 12.4 V, fuel ≥ ¼ tank, coolant at operating temp, transmission in P (auto) or N (manual), parking brake on, engine hood closed, outdoor/ventilated area

Step-by-step procedure

Step-by-step procedure

1. Park outdoors or in a well-ventilated area. Parking brake on, transmission in P (auto) or N (manual), engine hood closed. Exhaust temperature reaches up to 300 °C at the tailpipe – keep flammables away.
2. Connect the OBD2 scanner to the OBD2 port, switch ignition ON, and wait for VIN identification.
3. Navigate: Volkswagen → Automatic selection → Hot functions → Engine Control Module 1 → 01 – Engine electronics 1.6-2.0 TDI EU6.
4. Select 0001 – Service regeneration, particle filter.
5. Confirm test requirements (fuel ≥ ¼, parking brake set, hood closed, transmission in P/N) and read the safety warning about exhaust temperature. Press Done/Continue.
6. Evaluation during idling: let the engine run at idle. Scanner reads differential pressure at idle (in this case ~26 mbar).
7. When prompted, slowly raise RPM to ~2,500. Scanner reads pressure differential at increased idle (in this case ~92 mbar). Press Done/Continue when “Test successful” appears.
8. Initiate regeneration: depress the brake pedal when prompted. Scanner starts monitoring temperatures (before turbo / before DPF).
9. If a “Error during control unit communication” message appears but the RPM has risen and temperatures are climbing past 300–600 °C — regeneration is active in the background. Press Continue to keep the test running.
10. Monitor temperatures until they exceed ~600 °C and regeneration status shows “Warm-up phase 2” or further stages. Do not interrupt the cycle.
11. When regeneration completes, exit the hot function and run 0001 – Adapt Diesel Particle Filter (DPF) adapt. values. Confirm with Yes only if the DPF or related component was replaced — otherwise select No.
12. When prompted, switch ignition OFF, wait ~20 seconds for the ECU to save updated soot counters, then ignition ON.
13. Verify soot mass has dropped and no new DPF-related DTCs are stored. Clear any codes.

Additional Information & Compatibility Notes

On the Touran 5T 1.6/2.0 TDI EU6, the scanner may briefly display an “Error during control unit communication” message during the regeneration phase. This is a known quirk: as long as RPM stays elevated and exhaust temperatures rise above 500–600 °C, regeneration is actively running.

Pressing Continue keeps the session alive. If soot load is critically high or ash saturated, the ECU will refuse the forced regeneration and the DPF will require off-car cleaning or replacement.

Before using or purchasing any diagnostic tool for this procedure, always verify compatibility with your exact vehicle model, year and system configuration. Supported functions may vary depending on software version, hardware revision and regional limitations.
