      Ok the car is a OBD II MkIII Cabrio with a VR6 swap. The problem we are having is that the ECU is failing emmisions due to it's readiness state. It was fine and it checked out the last time it was at the referee, so I think it was somehow reset when the col pack was changed along with the 02's and the cat...

      From what I understand you can force this state of readiness through the VAG-COM... Does anyone know the steps to do this?

      You cannot force the readiness. The readiness state changes as certain self-tests are performed.

      There is a procedure that will allow the car to run these self tests and if they all pass your readiness will be properly set. That procedure varies from engine to engine, you will need to find the documentation for your particular car.

      Maybe we should have a sticky thread on performing the readiness test on a variety of engines. Though this is not the procedure for your car, the generic title you've got serves to become such a thread.

      This is the procedure for the AWV, though I would think it would be the same for APH, AWD, AWW, and AWP as well (MkIV transverse 1.8T) -- someone with Bentleys for those engine codes can confirm:

      1. Turn on car but do not start engine.
      2. Connect VAG-COM and go to 01 - Engine Module
      3. Clear DTCs
      4. Perform Basic Settings, Group 060 - Throttle Body Alignment
      5. Start the engine
      6. Go to Measuring Block Group 034
      7. Wait or rev engine around 2200 RPM until catalytic converter is over 350 degrees C
      8. Perform Basic Settings, Group 034 while revving between 1800-2200 RPM - O2 Sensor Aging Test
      9. Go to Measuring Block Group 046
      10. Wait or rev engine until cat is over 440 deg. C
      11. Perform Basic Settings, Group 046 while revving between 1800-2200 RPM - Catalytic Converter Test
      12. Perform Basic Settings, Group 077 with engine at idle - Secondary Air System Test
      13. Perform Basic Settings, Group 070 with engine at idle, if Reed Op. shows briefly open and close gas cap then repeat test - EVAP System Test

      PanEuropean had posted how to set the readiness for the BAP (W12) engine in this fourm. Could someone dig it up?

      Readiness code [for AWW and AWP 1.8t engines]
      Readiness code [for AWD 1.8t engine]
      Readiness code [for TDI: ALH, BEV]
      Readiness code [for 2.0l: AEG, AVH, AZH]
