Good day Gentlemen


I have one of the most frustrating problems on my Audi with my brake lights


When the ignition is off position my brake lights(tail lights) work perfectly. If you step on the brake pedal the lights comes on and if you leave the pedal the lights go off.
But when you turn the ignition to on the brake lights comes on and stays on while driving,


I have changed the brake lights switch twice, looked at all fuses.


Nobody can advise me what is wrong, can anybody please assist?


Best regards
Alwyn
