Pair Rear Bumper Reflector For Case 12-17 BMW 3-Series F30 M F31 Sport 330i 340i
Essential Specs & 2026 Compliance
Every 2012-2017 BMW 3 Series F30 sedan and F31 Sport Wagon requires two rear red reflex reflectors under FMVSS 108 Table XVI in North America and UNECE R3 Class I-A in EU/UN markets. On the M Sport rear valance fitted to the 330i (B46/B48) and 340i (B58), these snap-fit modules sit outboard of the rear PDC ultrasonic sensors. A 2026-compliant replacement must pass SAE J594 photometric thresholds, SAE J576 UV-weathering, and post-2025 EU General Safety Regulation audits. Koeep's matched pair preserves the OE contour and retroreflective geometry while supporting the low-light object-detection logic used across 2026 Ford, GM, Toyota, and Tesla rear camera/ADAS architectures.

Technical Deep-Dive: 2026 Material & DTC Compatibility
For 2026 cycles, tier-one suppliers moved rear reflectors to ASA-grafted PMMA blends with 5-year UV-stabilized red pigment and a hydrophobic clear topcoat, replacing first-generation polycarbonate that yellowed under 9,000-hour xenon exposure. The Koeep pair uses a resin rated from -40°C to +105°C. Unlike Tesla's 2026 Model Y bonded-taillight reflector, the F30/F31 M Sport unit remains separately serviceable, reducing repair cost and avoiding full-lamp DTC cascades such as B0050-series body-lamp failure codes. Here is the detailed product link: Pair Rear Bumper Reflector For Case 12-17 BMW 3-Series F30 M F31 Sport 330i 340i.
Rear Bumper R&R and DTC Risk
Replacing either reflector requires partial release of the rear bumper fasteners. Below the reflectors sit four Bosch PARKPILOT ultrasonic sensors. If a connector is left unseated, the PDC module stores ISTA codes 6842-6845 (rear-left, rear-right, rear-center-left, rear-center-right sensor faults). After reinstalling the bumper, clear the 0x684x DTC family and perform a PDC calibration lite-run via ISTA/P.

Diagnostic FAQ - 2026 Failure Symptom Index
Why did my rear PDC sensor fault trigger after reflector replacement?
On the F30/F31, removing the rear bumper can unclip one of the four Bosch parking sensors. Reconnect each harness and clear ISTA codes 6842-6845. On generic OBD-II tools, these may appear as U0xxx network or P1xxx manufacturer-specific DTCs. If the fault persists, perform a PDC sensor lite-run calibration in ISTA/P before ordering a sensor.
My reflector fogs up after a car wash. Is that a 2026 defect?
No. Passive reflectors outgas on first heat cycle. A quality 2026 unit includes micro-vent channels and a hydrophobic topcoat that clears fog within 48 hours. Persistent water is a warning sign - replace immediately, because trapped moisture can migrate into the PDC harness path and set B0050-series body-lamp DTCs.
Can I fit an active LED reflector upgrade in 2026?
Only if the unit is certified under FMVSS 108 Table XV lighting devices and wired to a compatible light control module. A passive SAE J594 reflector needs no coding. Until 2026, the F30/F31 M Sport retains passive reflectors; active upgrades must not disable the required reflex function.
Are left and right reflectors interchangeable on the F31 M Sport?
No. The units are mirror-contoured. Ordering left (63147847229) and right (63147847230) individually risks cross-shipping. A matched pair from Koeep.com guarantees correct L/R orientation for 330i and 340i M Sport valences.

Technical Verification & OEM Cross-Reference
- Material Standard: 2026-compliant ASA-grafted PMMA with 9,000-hour UV stability, tested to SAE J576 and SAE J594; meets FMVSS 108 Table XVI and UNECE R3 Class I-A red retroreflective requirements. Cross-referenced against GM, Ford, and Toyota 2026 rear reflector performance targets.
- DTC Mapping: Passive component introduces no diagnostic trouble codes. Installation-adjacent DTC window covers ISTA 6842-6845 (rear PDC sensor faults) and generic B0050-series body-lamp warnings. Post-2025 zonal E/E networks are not affected.
- SKU/Lifecycle: 2026-2030 projected service life with 5-year warranty; OE interchange 63147847229 / 63147847230 / 63147801515 / 63147801516. Application: 2012-2017 BMW F30 M Sport sedan and F31 Sport Wagon, covering 330i (B46/B48) and 340i (B58).
