This genuine OEM Audi tail light bulb socket / holder (4M0945221A) is a used, stock part removed from a donor vehicle. It secures the bulb and completes the electrical circuit for the tail, brake, or turn signal lights. When this socket fails, common symptoms include intermittent lighting, a bulb-out warning, or a complete loss of function in that portion of the taillamp—often without a blown bulb.
