    Cant start the engine. SAFE on Dashboard


    I have the car for well over 8 years. Once or twice a year when I try to start the engine nothing happens and it says SAFE on the dashboard. The only solution to this is to remove the positive terminal from the battery for 30 seconds. This is what I get with VCDS immediately after the issue occurred. Any ideas on where the issue is, I think that after 8 years it is time to be fixed.

    Removed. Data from a clone/pirate/hacked version of VCDS is not welcome here.

    That looks the likely culprit to me - it could be a communications glitch between the transponder in the key and the receiver ring in the ignition barrel.
    A friend's old Seat Leon used to do it occasionally.

    See if clearing that fault code will allow it to start.

    There's also more info here:

    Edit - having said that, something's not right here:

    Apparently I should put something witty or profound in here.....

    It's not unknown for the connections to the immobiliser sense coil to be intermittent, would be worth checking in that area.

    Hacked car. Hacked VCDS.

    Getting help on this forum requires the use of a legitimate VCDS system.

    They are available directly from us:

    ... Or from any of our authorized resellers:

    Let us know if/when you get one and we'll adjust your forum status.

    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.
