reset

try this as we dont' have info on polo model. With ignition off hold the 0.0 button, turn the ignition on (do not start). While still holding 0.0 button, press the hour and minute buttons at the same time. The Wrench light should go out almost instantly. Release the buttons and turn the ignition off and remove the key. Wait for the IPC to power down (approx. 5-10 seconds). Start the car and make sure the wrench is gone.
