The Audi door chime is the stock warning tone built into Audi dashboards, heard when a door opens with the key in the ignition or the lights left on. It was never a meme sound on its own; car channels and TikTok creators started ripping it as a clean sample of a gentle electronic ding associated with luxury cars. Today it appears in vehicle walkarounds, 'POV you own a German car' jokes and edits where a premium chime undercuts a cheap or broken-down car on screen.
