Have a Tesla-experienced technician complete the repair and the applicable software checks. The job includes protecting the paint, replacing the correct side, reconnecting the camera and lamp wiring, checking the view and signal, and completing the required reset and calibration procedure. 01 Fit the correct side. Remove the failed unit and seat the replacement securely in the fender opening. 02 Verify camera and signal operation. Confirm the camera feed, turn signal and connector security before closing the repair. 03 Clear calibration data and complete calibration.

Keep your fitment details, order and after-sales support together with TESERY. Review our shipping policy and return policy for your destination and order. Before you order Questions, answered. Is this the camera assembly or only a cover? It is the complete side repeater camera, turn-signal and molded housing assembly shown. It is not a decorative overlay. Does it fit a Model 3 2023.10+ or Model 3 Highland 2024+? Yes, for the refreshed Model 3 application with HW4/AI4 side repeater hardware. Choose the vehicle's left or right side. Does it fit a Model Y Juniper 2025+? Yes, for the Juniper refresh application with the matching side-camera hardware. For a pre-Juniper Model Y, send TESERY a photo of the removed part label and connector before ordering. Does it fit a Model Y 2023+, 2024+ or 2024.5–2024.12? Yes, for those Model Y applications with 4.0 Version Camera hardware. If your vehicle sits near a production change, send TESERY a photo of the existing part label to confirm compatibility. Is left always the driver's side? Only on a left-hand-drive vehicle. On a right-hand-drive vehicle, the vehicle's left side is the passenger side. Imagine sitting in the car and looking forward. Will I receive a pair? No. Left Side and Right Side each supply one assembly. To replace both sides, add one of each to the cart. Is this a genuine Tesla part? No. It is a new aftermarket replacement supplied by TESERY. The OE reference numbers identify the replacement application. Is calibration needed after replacement? Yes. Plan for the applicable DAS reset and camera calibration procedure after installation, followed by the required manual-driving self-calibration. Can this upgrade an older Model 3 or Model Y to HW4? No. The camera replaces compatible existing HW4/AI4 side repeater hardware. It does not convert legacy camera architecture or unlock software features. Made simple Your refreshed Tesla. Your side. One complete assembly. Select Left Side or Right Side—and send TESERY the current part label if your vehicle sits near a production change.
