  1. Before working on the high-voltage system of a VW hybrid or EV (e.g., ID.4), what is the first essential best practice?

    Answer: De-energize the HV system following the VW procedure and verify zero voltage with a rated meter

    Only a qualified technician should de-energize the HV system per VW procedure and verify absence of voltage before work.

  2. What PPE is specifically required when handling high-voltage EV components?

    Answer: Insulated gloves rated for the voltage, inspected before use, with leather protectors

    Voltage-rated insulating gloves must be air-tested for pinholes and worn with leather protectors for HV work.

  3. When flashing (updating) a control module with ODIS, which practice prevents module failure?

    Answer: Connect a stable battery charger/power supply to maintain system voltage

    A voltage drop during programming can corrupt the module, so a stable power supply is required.

  4. After replacing a windshield on a VW equipped with a front camera for Lane Assist, what is required?

    Answer: Calibrate the front camera using the specified procedure and target equipment

    ADAS cameras must be calibrated after windshield replacement so lane and collision systems aim correctly.

  5. A technician finds a worn part not related to the customer's concern. What is the best practice?

    Answer: Document it and inform the service advisor so the customer can approve or decline

    Additional work requires customer authorization, and documenting findings protects both customer and shop.

  6. Which practice best describes a logical diagnostic approach on a VW?

    Answer: Verify the concern, check TSBs, run Guided Fault Finding, test, then repair and verify

    A systematic process with verification avoids unnecessary part replacement and ensures the fix is confirmed.

  7. Why should a torque wrench be stored at its lowest setting (click-type) after use?

    Answer: To relieve spring tension and maintain calibration accuracy

    Leaving the spring compressed can cause it to fatigue, making the wrench read inaccurately over time.
