U0575 code meaning
Invalid Data Received From Lighting Driver Control Module B
What U0575 means
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 Glare-free high beam or light animations may be withdrawn, while basic low and high beam should remain.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.

Symptoms of U0575
- Glare-free high beam switched off with a lighting message
- Individual LED segments dark or flickering
Common causes of U0575
- PossibleSoftware of driver module B outdated or inconsistent with the other modules
- PossibleDefective LED segment producing fault reports the receiver cannot match
- Less likelyLighting driver control module B internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0575 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 75 | The exact fault in that area. |
What to do next
- Note U0575 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0575
What does U0575 mean?
U0575 means "Invalid Data Received From Lighting Driver Control Module B". U0575 flags implausible data from lighting driver control module B. It is a generic code, so it means the same on every make.
Is it safe to drive with U0575?
U0575 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0575 fail an emissions test?
U0575 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0575 to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. This is a job for a workshop.
Will U0575 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
