U0575Invalid Data Received From Lighting Driver Control Module B
- Generic OBD-II code · Network
- How the car detects it
- U0575 flags implausible data from lighting driver control module B. Matrix headlamps split the high beam into many LEDs that a control unit switches individually; Audi introduced the first such glare-free system on the 2013 A8 with 25 segments per lamp. With several driver modules on board, the controller in charge expects regular and consistent status from each of them. Lincoln's 2025 Navigator names four headlamp driver modules, lettered A to D, and updated them over the air in October 2025; where each letter sits is not stated. Neither U0575 nor partner U0274 is documented by a manufacturer. Glare-free high beam or light animations may be withdrawn, while basic low and high beam should remain. No MIL.
