1.9l/2.0l 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.

  • Enable Regeneration by Entering 21295.

[Do It!]

[Meas. Blocks - 08]
Select both Groups at once 070 and 075.
[Go!]
MVB 070.1: Regeneration Status (xxxxxxx1 = Normal Regeneration active, xxxxxx1x = Forced Regeneration active)
MVB 070.3: Regeneration Counter/Timer
MVB 075.1: Exhaust Gas Temperature before Turbo Charger
MVB 075.2: Exhaust Gas Temperature before Particle Filter
MVB 075.3: Particle Filter Load
MVB 075.4: Exhaust Gas Temperature after Particle Filter

Now Start the Driving Cycle and keep watching the Measuring Blocks (2nd Person required).

[Done, Go Back]
