Audi A6 Quattro
Report: Brake Light Switch Failure
Audi A6 Quattro Problem
Model Year Affected: 2003
Break light switch becomes inoperable, causing ABS and No traction control light come on, causing brake lights to stay on even with the engine shut off and car locked (as if someone is stepping on the brake pedal). Problem corrected by replacing the brake light switch (located in the driver's side compartment, above the brake pedal).
