Diesel Particle Filter Emergency Regeneration
1.4l/1.9l/2.0l R4 & 2.5l R5 TDI
Prerequisites (General):
- Ignition ON
- Engine ON (Idle)
- Coolant Temperature above 50 °C (see MVB 002.4)
- Particle Filter Load below Specification (see MVB 075.3, VAG-COM should give the specified value)
- If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.
- Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)
Conditions (Driving Cycle):
- Vehicle Speed between 30-60 km/h (18-37 MPH)
- Engine Speed between 1500-2500 RPM (4th or 5th Gear, Automatic Transmission in Tiptronic)
- Duration approx. 15-20 Minutes
- Exhaust Gas Temperature before Turbo Charger above 700 °C
Drive the car based on the above conditions until the Particle Filter Load is as low as possible (close to 0 %). In case the regeneration fails there can either be problems with the Driving Cycle Conditions or with the Engine Hardware.
