What is the reason for the Audi Q5 not responding when starting and the dashboard not lighting up?

Audi Q5 not responding when starting and the dashboard not lighting up requires checking whether the battery has an "open circuit". Apart from wiring faults, it may be that the battery has an open circuit fault. The following are specific reasons: Audi Q5 not responding when starting due to battery open circuit: Open circuit mainly refers to the phenomenon where the internal connection of the battery is disconnected, rendering the battery ineffective. The main manifestations are: the charger shows a green light when charging, and when starting the vehicle, both the dashboard and the entire vehicle show no response. There are two special forms of open circuit: micro open circuit: refers to the phenomenon where, during the driving process of the vehicle, due to a loose connection inside the battery, the vehicle intermittently has power and then no response, which is a battery quality issue; 0V open circuit: refers to a battery with a measured terminal voltage of 2V or less, mostly caused by high current, and is not a quality issue. Other reasons for Audi Q5 not responding when starting: When the electric vehicle has power but does not respond when starting and the dashboard does not light up, apart from the battery open circuit phenomenon, it could also be that the electric vehicle's fuse is blown or the ignition lock is broken. It is recommended to push the electric vehicle to a nearby repair point for inspection and repair, and avoid dismantling the electric vehicle privately to prevent further damage.
When the Audi Q5 fails to start and the dashboard remains dark, my first thought is a battery issue, such as aging or loose connections causing a complete power loss. I’ve experienced this before with another car—dead battery leading to ignition failure and a blank dashboard, which was resolved with a jump-start from a friend. Now, with the Q5, I’d check for corrosion or looseness at the terminals and use a multimeter to measure voltage; if it’s below 12 volts, don’t force it. Another common culprit is a blown fuse, especially the main power fuse located in the engine bay or driver-side fuse box—if it’s burnt out, the dashboard won’t light up, and the car won’t start. For smart keys, a depleted battery or signal interference could be the issue, though a dark dashboard usually points to the battery. In any case, stay calm, perform basic checks first, and call a professional if needed—safety comes first to avoid getting stranded at night.
