The BMW 3 Series F30/F35 sedan family and F34 Gran Turismo share a generation but do not use one universal headlight. Tangma lists a 2013-2018 F30/F35 LED headlight upgrade and a separate 2013+ F34 GT LED headlight assembly. Correct chassis identification is the first compatibility step.
Quick compatibility answer
Use the F30/F35 product only for the supported sedan or long-wheelbase sedan configuration, and the F34 product only for Gran Turismo applications. Verify VIN chassis code, production date, pre-LCI or LCI body, factory halogen/xenon/LED system, connectors, modules and driving market.
Why F30 and F34 lamps are different
The F34 GT has a different front-end shape, hood line and lamp housing from the F30 sedan. Similar lighting graphics do not make the assemblies interchangeable. Compare mounting tabs, outer lens outline and rear housing before discussing electrical compatibility.
F30 vs F35
F35 is a long-wheelbase regional sedan based on the F30 family. Some front lighting components may appear similar, but regional trim, production changes and wiring can differ. Confirm the VIN and original part number rather than assuming every F30-labelled lamp fits every F35.
Pre-LCI vs LCI
The Life Cycle Impulse facelift can change lamp design and electronics. Use the VIN build date and front photo, not registration year alone. A conversion across facelift versions may require additional front-end parts or a specific assembly version.
Factory-light checklist
- Halogen, xenon, standard LED or adaptive LED.
- Automatic leveling and headlight washer equipment.
- Adaptive/steering functions and high-beam assistance.
- Main connector, external modules and housing part number.
- Left-hand-drive or right-hand-drive beam requirement.
Coding and installation
Changing lighting technology can require adapters, module transfer, load management or vehicle coding. Professional installation should include a diagnostic scan before and after the work, function testing, moisture inspection and beam alignment. Test-fit both lamps before tightening bumper and fender interfaces.
What to send before ordering
- VIN and exact production date.
- F30, F35 or F34 chassis confirmation.
- Front and rear headlight photographs.
- Connector and module part-number photos.
- Country, steering position and current lighting faults.

Frequently asked questions
Will F30 headlights fit an F34 GT?
No. The F30/F35 sedan family and F34 Gran Turismo use different headlight shapes and mounting geometry. Choose the chassis-specific product.
Which year models are compatible?
The F30/F35 product is listed for 2013-2018 applications, while the F34 GT assembly is listed for 2013+. Confirm production date and facelift version.
Does coding require any changes?
It may. Requirements depend on the original halogen, xenon or LED system, adaptive functions, modules and the selected assembly version.
What modules are included?
Included drivers, ballasts, adapters and control modules vary by product configuration. Request a written packing list before purchase.
How difficult is installation?
This is an advanced retrofit when changing lamp technology or facelift version. Professional fitting, diagnostics, coding evaluation and beam alignment are recommended.
