💡 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, smart electronic touch-button releases, high-voltage battery cutoff response protocols, and mechanical internal emergency override cables remain 100% intact.

✨ Premium Intelligent Modification by LiTanglee

Infuse high-tier smart luxury into your lifestyle EV with the Electric Soft Close Door Upgrade Kit For Deepal S05 / C857 Platform. Meticulously engineered by LiTanglee to overcome the sudden air backpressure inside the tightly sealed cabin structure of the S05 series, this premium 4-door upgrade introduces fluid, silent suction mechanics that pull the doors completely flush without requiring forceful slamming.

• 🤫 Intelligent High-Efficiency Whisper Suction: The LiTanglee soft close door system utilizes premium, space-optimized high-torque DC operating motors tailored perfectly for the S05 framework. It draws doors fully closed with whisper-quiet elegance, eliminating structural stress from slamming.
• 🛡️ OEM Lock Retention Architecture: Engineered to augment your vehicle's existing structural frame without removing the underlying factory lock block. It pairs flawlessly with Deepal's digital keyless systems, intelligent door electronics, and central logic networks without triggering BCM diagnostic faults.
  
• 🛠️ 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

⚠️ DEEPAL S05 (C857 PLATFORM) CRITICAL TECHNICAL INSTALLATION NOTICE

• Side Passenger Doors Only Notice: This upgrade kit is designed exclusively for the **4 side-swinging passenger doors**. It does NOT include or support components for the upward-opening rear tailgate power lift system.
• 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: Power routing is fully localized. 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 EV digital signal bus, avoiding battery drainage or vehicle sleep network interference.
• 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.
• Compact Door Cavity Window Clearance Pre-Test: Due to the highly compact internal door shell layout of the S05 platform, clearance limits are extremely tight. You must completely roll down the window glass manually after mounting the kit to visually verify that the descending glass frame completely clears the upgraded motor housing and bowden suction cables inside the door panel to prevent any rubbing or scratching.
• High-Elastic Weatherstripping Striker Adjustment: The Deepal S05 utilizes resilient weatherstripping gaskets for acoustic performance. If the secondary suction pull stops halfway or encounters heavy compression resistance from cabin backpressure, loosen the vehicle chassis door striker bolt slightly and move it outward by 0.5mm to achieve a fluid and effortless soft-closing cycle.
