How to read diagnostic error codes on the Opel Corsa display

Model: Vauxhall Corsa Corsa E - Years 2014-2019
Part: Onboard computer

In this video, we will see how to read the Diagnostic Trouble Codes (DTC) on Opel/Vauxhall vehicles, through a hidden diagnostic menu: to access it, we must press and hold down the accelerator and brake pedals while turning on the instrument panel. Wait for the error reading mode, which will be indicated by the engine light flashing in sequence, thus communicating the error code through the flashes: each number is represented by 4 flashes, and zero is represented by 10 flashes. Therefore, we will need to be patient and have a notebook to keep track of the flashes and note down the resulting number.
