KUFATEC Lane Change Assistant Wiring Harness – VW ID.3 (E11) / Cupra Born (K11) (46376)
This specific wiring harness from the German retrofit expert KUFATEC (part number 46376) is designed for retrofitting the original Lane Change Assistant (Blind Spot Monitor / Side Assist) and Rear Cross Traffic Alert for VW ID.3 (E11) and Seat / Cupra Born (K11) electric vehicles.
The harness premium-connects the radar sensors located inside the rear bumper corners to the main vehicle gateway and the warning indicators in both exterior wing mirrors. The system monitors the blind spots at speeds above 30 km/h, while the integrated Rear Cross Traffic Alert helps you safely back out of parking spaces by detecting oncoming cross-traffic.
If there is a wiring failure, loose connection, or radar fault, the car's digital cockpit will display:
Yellow Assistant Warning Icon: Two cars side-by-side with a yellow exclamation mark.
Dashboard Message: Text warnings such as "Side Assist currently unavailable" or "Fault: Lane Change Assistant and Rear Cross Traffic Alert".
Diagnostic Fault Codes (OBD): Scanning the blind spot radar modules (addresses 3C and CF) will log errors like "No communication with control module", "Short to ground", or "Databus missing message".
Important Installation Note: This package contains the wiring harness only. Additional hardware components (such as radar sensors, bumper brackets, and mirror glasses with LED indicators) are required to complete the installation. After hardware fitting, the system must be software-coded using the KUFATEC coding dongle 42288.
