C108000 Code: Meaning & Diagnostic Guide

“Left-/right hand driving switch-over active,” reported in the Headlamp Range Control module. The source confirms the code and description on a 2015 Audi A7, but does not establish applicability to a 2021+ BEV or PHEV.

Reference status: This page preserves source-backed code definitions for discovery. Manufacturer/model applicability, repair steps and safety conclusions are not treated as verified unless a manufacturer-specific verified report is available.

What does C108000 mean?

  • GENERIC: “Left-/right hand driving switch-over active,” reported in the Headlamp Range Control module. The source confirms the code and description on a 2015 Audi A7, but does not establish applicability to a 2021+ BEV or PHEV. Source

Is C108000 generic or manufacturer-specific?

C108000 has a generic source-backed definition in this database. The exact vehicle make, model, year and powertrain should be confirmed before using a definition for diagnosis.

C108000 symptoms

A diagnostic code identifies a detected condition; it does not by itself prove which component has failed. Symptoms can differ between vehicles. Record the exact warning message, any additional codes, and the operating condition when C108000 appeared.

Possible causes of C108000

Possible causes depend on the vehicle-specific definition and test results. Do not conclude that a named component has failed from C108000 alone; wiring, connections, control conditions and component tests should be evaluated using manufacturer procedures.

How to diagnose C108000

  1. Confirm the exact C108000 reading with a compatible scan tool and record any accompanying codes.
  2. Confirm the vehicle make, model, model year and powertrain before applying a reference definition.
  3. Prefer a verified manufacturer-specific report when one is available.
  4. Follow the manufacturer diagnostic procedure before replacing parts.

How to fix C108000

There is no safe universal parts-replacement fix for C108000 without vehicle-specific evidence. The correct resolution depends on the confirmed definition and diagnostic test results.

Can I drive with C108000?

A universal drive/no-drive answer cannot be inferred from C108000 alone. Follow the vehicle warning and manufacturer instructions.

C108000 frequently asked questions

What does C108000 mean?

“Left-/right hand driving switch-over active,” reported in the Headlamp Range Control module. The source confirms the code and description on a 2015 Audi A7, but does not establish applicability to a 2021+ BEV or PHEV.

Can different manufacturers use C108000 differently?

Yes. Generic definitions and manufacturer-labelled definitions can coexist, so vehicle context matters.

Should I replace a part immediately?

No. A code is a diagnostic starting point, not proof that a named component has failed.
