    Forced OBD readiness with VCDS

    I have done a repair on a 2012 Touareg TDI with the help of VCDS but my OBD readiness is not resetting.

    I saw some postings that tests can be run with the old Vag-com but my VCDS interface does not support those in Basic Settings.

    Is there a way to force OBD II readiness with VCDS.

    right now, when I click "readiness", in the engine module, it is stating that all systems are ready, however when I click OBD-II functions and hit on OBD readiness, two of the modules are not ready

    O2 heating
    Catalytic Converter

    Does anyone know how to force them to be ready with a test or something? I have driven 300 miles already and they have not reset.

    There is no way to "Force Readiness" on any vehicle. You may be able to force certain tests, but there's always the question whether all proper conditions have been met.

    Looking at the data for your ECU, there don't seem to be tests explicitly for O2 Heating or the Catalytic Converter, but there is:

    IDE00553 -- Automatic test sequence

    However, I don't have an actual procedure for it.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    So the two monitor had not shown ready after driving 500 miles BUT CA BAR rules say that a Diesel can pass smog with two monitors ready (only EVAP for gas cars) which the smog guy didn't know. So all set and roadworthy finally! Thank you and VCDS for making this project succcesful !!

    Reset my service interval and and may have deleted some codes and now I can't get car inspected because of OBD readiness issues. Any clues how to speed this up to return to inspection station ?

    That's this car, right?

    I would try this Basic Setting in the Engine:
    IDE00553 -- Automatic test sequence

    After initiating Basic Settings, the hold a foot on the brake pedal and floor the accelerator pedal. The ECU will then holdd different RPM points and run through all of the tests. While in Basic Settings, the Show Measuring Data button be used to display "IDE00727 Test steps still to be performed" or similar to watch the remaining steps count down to zero.

    Thanks for the quick response, it is in fact the same car but it has a manual transmission, can I put it in first with e brake and wheel chock and perform the same procedure just letting up a little on the clutch? I have also read that if you have a full tank of gas the evap monitor may not perform a test.

    On an automatic car, this would be done with the shifter in Park. On a manual car: Neutral. Service brake must be held. There should be no need to touch the clutch.

    Yes, but only after initiating the Basic Setting, and while holding the brake pedal firmly with your left foot. Assuming the Basic Setting is active, the ECU should then run the engine at the speeds it deems necessary to conduct the tests.
