BMW G30 LCI
Complete Conversion Checklist
Planning a complete BMW G30 LCI conversion? Use this master checklist to make sure the important parts, electrical work, installation requirements and final checks are covered before the project is finished.
Everything You Need To Check Before The Conversion
A complete BMW G30 LCI conversion is easier to manage when the whole project is planned before individual parts are ordered. This master checklist brings the main areas together so you can verify that no important part of the project has been overlooked.
Not every G30 needs exactly the same parts or electrical work. Production details, existing equipment, selected LCI components and market specification can change the final retrofit requirements.
Before You Buy
Start with the car, not the parts. Confirm the existing configuration and define exactly how complete the LCI conversion should be.
Identify The Vehicle
Confirm the BMW G30 model, production date, VIN information and current vehicle specification.
Check Existing Equipment
Identify the current headlights, tail lights and relevant exterior equipment before selecting the LCI parts.
Define The LCI Configuration
Decide whether the project is a complete facelift or a selected front, rear or lighting upgrade.
Check Market Specification
EU and US specification can matter for lighting functions, configuration and retrofit compatibility.
See Market SpecificationConfirm Component Compatibility
Match the exact target parts with the vehicle before ordering individual components.
See The Parts GuidePlan The Complete Project
Consider exterior parts, wiring, modules, coding, installation, painting and final testing as one project.
Read The Conversion GuideExterior Conversion Parts
These are the main exterior areas to check for a full G30 LCI facelift. The exact combination depends on the vehicle and chosen LCI specification.
LCI Front Bumper
Confirm the complete bumper setup, including related trims, ducts and mounting components where required.
Front Bumper & Grille GuideLCI Kidney Grilles
Choose grilles that match the selected LCI bumper and the intended front-end configuration.
Check Grille FitmentLCI Headlights
Confirm the exact LCI headlight version, physical fitment, connectors, wiring and possible module requirements.
Headlight Retrofit GuideLCI Tail Lights
Confirm the correct LCI rear light version and the wiring, electrical and mounting requirements for the vehicle.
Tail Light Retrofit GuideRear Diffuser & Spoiler
Check the LCI-compatible rear diffuser, spoiler and related mounting components required for the selected rear configuration.
Rear Diffuser & Spoiler GuideComplete Parts List
Do not order only the large visible components. Check the complete combination of exterior parts, lighting components and supporting hardware before starting the installation.
BMW G30 LCI Retrofit Parts GuideElectrical & Coding
The electrical side should be planned together with the selected lights and vehicle configuration. The checklist only identifies what needs to be checked; the detailed retrofit guide covers the technical implementation.
Wiring & Retrofit Harnesses
Check whether the selected headlights or tail lights require adapters, wiring changes or retrofit harnesses.
Headlight Wiring GuideConnectors & Electrical Connections
Verify the existing connectors against the exact target components before installation.
Tail Light Wiring GuideModules & Control Units
Determine whether the selected retrofit combination requires compatible modules or additional electrical components.
Modules & Compatibility GuideVehicle Configuration
Confirm how the new equipment should be represented in the vehicle configuration before affected modules are coded.
Coding & Configuration GuideCoding / Programming
Make sure the required coding or, where applicable, programming is included in the project plan for the confirmed hardware.
Read The Coding GuideDiagnostics After Coding
Allow time for a diagnostic check, fault-memory review and functional verification after the electrical work is complete.
Diagnostic GuideInstallation Requirements
The small components are easy to overlook. Prepare the mounting and finishing hardware before the car is taken apart.
Mounting Brackets
Confirm all brackets and supports required for the selected bumper, lights and exterior components.
Clips & Fasteners
Check clips, screws, bolts, retainers and other small fasteners that may need replacement or addition.
Trim & Supporting Parts
Look for surrounding trim pieces or smaller components that are part of the complete installation rather than the main part itself.
Tools & Installation Equipment
Have the appropriate tools and protection available before removing the original exterior components.
Fitment Before Final Assembly
Check alignment and panel gaps before committing to final installation and finishing.
Protect Painted Surfaces
Use suitable protection during disassembly and installation to avoid unnecessary marks or damage.
Painting & Bodywork
Painting is part of the conversion whenever the selected body components do not already match the vehicle.
Check Which Parts Need Paint
Identify bumper, diffuser, spoiler or other body components that require painting or refinishing.
Confirm Paint Code
Use the vehicle's correct paint information before bodywork or refinishing begins.
Check Panel Gaps
Verify fitment and alignment before final paint wherever possible so bodywork is not completed around an incorrect fit.
Complete Bodywork
Finish any required preparation, repair or adjustment before the final exterior assembly.
Final Installation & Testing
The conversion is not finished when all the parts are bolted on. Verify fitment, electrical functions, coding and warnings.
Check Exterior Fitment
Inspect bumper, grilles, lights, diffuser, spoiler and surrounding panels for correct alignment and secure mounting.
Check Front-End FitmentTest Headlights
Check the relevant low beam, high beam, daytime lighting, indicators and additional supported functions.
Headlight Testing GuideTest Tail Lights
Verify rear lighting functions and confirm that the installed lights operate correctly with the vehicle configuration.
Tail Light Testing GuideCheck Warning Messages
Do not rely only on a visual inspection. Check the dashboard and diagnostic system for relevant warnings or faults.
Diagnostics GuideVerify Coding
Confirm that the affected vehicle functions and installed retrofit equipment are correctly configured.
Coding GuideCheck Headlight Alignment
Verify final beam alignment and adjustment after headlight installation before normal road use.
