BMW 3 Series F30 LCI (B38 Engine) Boot Lid Inner Taillight | Genuine OEM

Description

If your BMW F30 3 Series equipped with the 1.5L B38 3-cylinder engine (typically 318i LCI models) has a cracked lens, failing LED light bars, or water ingress inside the boot lid light unit, replacing the inner taillight restores both factory rear aesthetics and electrical reliability. We supply workshop-vetted, original boot-lid mounted inner taillights specifically designed for the F30 LCI platform.

Because these are original BMW OEM assemblies, they feature the exact LED optical tube alignment, lens clarity, and internal weather seal perimeter that aftermarket copies lack, ensuring seamless light bar continuity across to your outer fender tail lamp.

• Factory-Spec LED Illumination: Restores the crisp, even light signature of your reverse lamps, rear fog lights, and running light bars without bulb-out dashboard errors.

• Weather-Tight Sealing: Built with factory rubber gasket perimeter profiles to prevent rain water from leaking through the mounting holes into your boot lid latch and wiring loom.

• Condition: Premium workshop-vetted original component; inspected for clean acrylic lens condition, crack-free mounting studs, intact wiring harness connectors, and 100% functional LED light guides.

Critical Considerations for F30 Inner Taillight Replacement:

• Pre-LCI vs. LCI (Life Cycle Impulse Facelift): The B38 engine was introduced during the F30 facelift transition (2015+ LCI models). Pre-facelift (Pre-LCI) models used halogen/incandescent inner bulbs, while LCI models utilize full LED light guide signatures with distinct plug configurations. Providing your VIN is mandatory to verify whether your car is a factory LCI or a Pre-LCI conversion.

• Side Specificity (Left / Passenger vs. Right / Driver): Inner taillights are asymmetrical and strictly side-specific. Always specify whether you require the Left (Passenger Side) or Right (Driver Side) inner boot unit.

• Check for Water Corrosion on the Plug: If your old light leaked internally, inspect the 4-pin electrical connector plug. Corroded pins will cause the new light to flicker or throw a “Rear Light Failure” warning. Clean the pins with contact cleaner before plugging in the replacement unit.

Workshop Pro-Tip: Don’t overtighten the 8mm plastic holding nuts! The inner light unit is secured through the boot lid sheet metal by small threaded plastic studs or metal clips. Overtightening them will snap the studs directly off the light’s plastic housing or deform the rubber gasket, causing instant water leaks into the boot lining. Snug them down firmly by hand with a nut driver until the gasket compresses evenly!
