    The main battery is dead and so the rear wheels are completely blocked and the Roadster cannot be moved even pushing it.
    Do you know how disengage the rear wheels with the HV battery dead?

    If a 2.x then you likely have a dead 12v as welll replacing that should allow you to get into tow mode through the VDS. If a 1.5 I do not know maybe feed power through the cigarette lighter but would wait for other comments first.

    In front of the right rear wheel under the splash shield is the junction box for the main 12v feed (large red wires). Hook 12v positive to that terminal and negative to the frame. That will give you enough power to put the car in tow mode.

    The 12V positive wire is only one or there are more of them?

    Bad news.... with a new service battery the VDS and the instruments panel remain dead, only traffic lights and exterior light are on. What else before disconnecting axales? I'm Ms 85D owner and president of Tesla Owners Club Italy, Ticino, San Marino. Thanks so much for your help!

    Inside the wheel well, under the splash shield,directly in front of the right rear wheel. The big red wire going into the little black box. You might have to remove the wheel. SAM_4088.JPG

    Your local service center should have, or can order, a Parking Pawl Brake Release dongle to use with their ProTool device to inject 12V power and a CAN signal to unlock the parking pawl. I recently dealt with the very same issue with a friend in Northern California who had a bricked Roadster, and the service center got the solenoid to disengage allowing the vehicle to roll freely. Let me know if the service center needs more information on the tool/dongle.
