⚠️ CRITICAL BUYER NOTICE: The flagship Li Mega (W01) comes standard with factory electric motorized rear sliding doors. Therefore, this upgrade kit is custom-engineered and sold STRICTLY as a FRONT 2-DOOR SET (Driver and Front Passenger doors). It does NOT include, nor does it support, any components for the rear sliding doors.

💡 IMPORTANT SYSTEM NOTE: This premium upgrade kit is designed exclusively as an UPGRADE to your original factory car lock mechanism. It does NOT replace your original primary OEM lock assembly. By seamlessly integrating with and retaining your factory lock, your vehicle's original smart crash-unlock safety certifications, anti-theft tracking modules, central locking logic codes, and mechanical internal emergency override cables remain 100% intact.

✨ Premium Intelligent Modification by LiTanglee

Bring executive-level luxury and effortless acoustic comfort to the front cabin of your flagship electric MPV with the Electric Soft Close Door Upgrade Kit For Li Mega / Lixiang Mega (W01) Series. Meticulously engineered by LiTanglee to overcome the high cabin air backpressure common in heavily soundproofed and aerodynamically optimized MPV cabins, this premium front 2-door upgrade introduces fluid, intelligent suction mechanics that pull the doors completely flush without forceful, jarring slamming.

• 🤫 Smooth & Whisper-Quiet Suction: The LiTanglee soft close door system features high-torque DC operating motors tailored for flagship luxury MPVs. It draws the heavy front doors fully closed with whisper-quiet elegance, eliminating high-velocity slam impacts and protecting the interior plastic door panel clips.
• 🛡️ OEM Lock Retention Architecture: Engineered to augment your vehicle's existing structural frame without removing the underlying factory lock block. It pairs seamlessly with Li Mega's smart proximity keyless systems, motorized flush pop-out handles, and central logic networks without triggering BCM diagnostic codes.
• 🛠️ 100% Non-Destructive Installation: Designed specifically for clean, professional vehicle modifications. The kit features a fully plug-and-play wiring configuration with no wire cutting, drilling, or paint modifications required, leaving your original vehicle warranty fully protected.

🎥 Installation & Demonstration Guide

⚠️ FOR LI MEGA (W01) CRITICAL TECHNICAL INSTALLATION NOTICE

• [STRICT WARNING] Front Cabin Doors Only: This kit is designed solely for the front left and front right swing doors of the Li Mega (W01). It CANNOT be applied to the rear sliding doors. Attempting to fit these parts onto rear doors will damage both the kit and the vehicle.
• Flush Retractable Door Handle Coordination: The Li Mega features smart motorized flush-mounted door handles. The LiTanglee upgrade kit is fully calibrated to work in parallel with this factory micro-switch signal architecture. Do not pull or force the handle manually during the soft-close suction cycle to ensure system synchronization.
• Strict No-Load & Shipping Tie Warning: Never connect power to actuate or bench-test the system before the upgrade kit is completely bolted into the door framework. Running the system under zero-load conditions can permanently warp the lock mechanism. Ensure the shipping cable tie on the lock tongue is cut off before assembly.
• Sponge / Foam Strip Removal Required: Carefully inspect the OEM factory lock block. You MUST completely peel off the black factory sealing sponge/foam layer from the contact surface. If left intact, the sponge will bunch up inside the upgrade latch mechanism, creating immense mechanical friction that causes motor return or suction cycle failure.
• Bracket Tab Alignment: When integrating the upgrade lock unit with the custom-molded mounting bracket, make sure to slide the bracket tabs firmly into the designated lower slots. Ensure it does not slide out of alignment toward the upper frame before securing the screws.
• 无损对插取电 Window Lifter In-Line Interception (OTA/BCM Isolation): Power routing is fully localized to the front door's 12V auxiliary system. Unplug the factory wire harness connector from the power window lifter motor, and insert the LiTanglee inline T-Harness adapter directly between the factory socket and the motor to safely intercept fused 12V power. This isolates the kit entirely from the smart vehicle BCM low-voltage digital signal bus and high-voltage drive systems, completely avoiding battery leakage, fault alerts, or issues during vehicle OTA firmware upgrades.
• Chassis Isolated Grounding Path: The black ground (GND) wire must be secured directly to an authenticated, bare-metal factory chassis grounding bolt inside the door framework. Do not link to painted reinforcement brackets or tap into digital logic grounds to ensure complete isolation from sensitive smart vehicle sensors.
• Door Cavity Window Clearance Pre-Test: Because the window pane descends deep into the door cavity shell, you must completely roll down the window glass manually after mounting the kit to visually verify that the moving glass frame completely clears the upgraded motor housing and bowden suction cables inside the door panel to prevent any contact or scratches.
• Acoustic Sealing & MPV Cabin Air Backpressure Adjustment: The Li Mega utilizes premium acoustic-insulated double-glazed glass and high-density rubber seals to achieve ultra-low wind noise (0.215 Cd). This creates intense backpressure inside the cabin when closing the front doors. If the secondary suction pull stops halfway or encounters excessive resistance, loosen the vehicle chassis door striker bolt slightly and move it outward by 0.5mm to achieve a fluid and effortless soft-closing cycle.
