MVB 108.3: Particle Filter Soot Mass (measured) Alternate group 241.3 if 108 is blank MVB 108.2: Particle Filter Soot Mass (calculated) Alternate group 241.2 if 108 is blank MVB 099.4: Exhaust Gas Temperature after Particle Filter MVB 099.3: Exhaust Gas Temperature before Particle Filter MVB 099.2: Exhaust Gas Temperature before Turbo Charger The Particle Filter Load should be as low as possible (close to 0 %) This process may take up to 30 minutes.Ĭheck the following groups after the regen.

If either the calculated or measured soot mass is above 30g but below 40g you can initiate a regeneration while standing (Idle will be raised etc.), a forced regeneration while driving is also possible. With the newer CR-TDI engines there are 2 different types of regenerations available depending on the actual soot mass/load. Now Start the Driving Cycle and keep watching the Measuring Blocks (2nd Person required). MVB 075.4: Exhaust Gas Temperature after Particle Filter MVB 075.2: Exhaust Gas Temperature before Particle Filter MVB 075.1: Exhaust Gas Temperature before Turbo Charger MVB 070.1: Regeneration Status (xxxxxxx1 = Normal Regeneration active, xxxxxx1x = Forced Regeneration active) In case the regeneration fails there can either be problems with the Driving Cycle Conditions or with the Engine Hardware. Exhaust Gas Temperature before Turbo Charger above 700 ☌ĭrive the car based on the above conditions until the Particle Filter Load is as low as possible (close to 0 %).Engine Speed between 1500-2500 RPM (4th or 5th Gear, Automatic Transmission in Tiptronic).Vehicle Speed between 30-60 km/h (18-37 MPH).

Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control).

If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.Particle Filter Load below Specification (see MVB 075.3, VCDS should give the specified value).Coolant Temperature above 50 ☌ (see MVB 002.4).
