    Immobilizer measuring blocks ERROR

    2001 TTQ has (recently) new battery. Worked OK for some time but now will not start. Has a 17978 Engine Start Blocked by Immobilizer code. Cleared the code and it doesn't come back after subsequent start attempts (also still doesn't start). Went to check the measuring blocks (link below) and it showed "ERROR: Group xxx Not Available" for the ones shown 022, 023, 024 and surfed around to discover some but all were ERROR. How can I see these values?

    Also, checked clutch switch and it changes state. Car key arms immobilizer when car is locked (red LED flashes). Will also try key #2 when I get my hands on it (currently it is out of town).

    And... any other advice for success (have not shorted battery cables together yet)?

    Please advise,
    Jon

    Are you checking those blocks in 25-Immobilizer? IIRC on that car, you need to look in 17-Instruments instead.

    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.

    Sorry to hear of your troubles. Could you post a complete autoscan of the TTQ please? We'd like to see what VCDS is seeing...

    Good call and thank you, was incorrectly looking at 25. Here are results for 17-Instruments:

    022 - 1114
    023 - 1116
    024 - 0000

    And scan:

    Does not seem to be an obvious problem with the immobilizer:

    That is not the immobilizer. That's the alarm, handled by 35 -- Centr. Locks

    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.

    In this model immo does not affect starter control.
    Check starter, wiring to it, IGN switch terminal 50.

    I believe 35-Central Locking can keep it from cranking if it thinks the car has not been unlocked appropriately.
