Shipping & Return

TESERY · HW4 replacement parts

Restore the side view.
Keep the repair precise.

Replace a failed side repeater camera and turn-signal assembly on your refreshed Model 3 or Model Y. Choose the vehicle's left or right side—without decoding the part yourself.

Left and right HW4 side repeater camera assemblies for Tesla Model 3 Highland and Model Y Juniper

Your fit. Already narrowed down.

For the refreshed
HW4 camera generation.

This replacement is intended for the newer side repeater camera hardware fitted to the refreshed vehicles below.

Your vehicle What to choose
Model 3 2023.10+ (3.0 Version Camera) Choose Left Side or Right Side in this listing.
Model 3 Highland 2024+ (3.0 Version Camera) Choose Left Side or Right Side in this listing.
Model Y 2023+ (3.0 Version Camera) Choose Left Side or Right Side in this listing.
Model Y 2024+ (3.0 Version Camera) Choose Left Side or Right Side in this listing.
Model Y 2024.5–2024.12 (3.0 Version Camera) Choose Left Side or Right Side in this listing.
Model Y Juniper 2025+ (3.0 Version Camera) Choose Left Side or Right Side in this listing.

Model year alone can be unreliable near production changes. If the car sits near a refresh boundary, the label on the removed assembly is the best confirmation.

One simple choice

Which side needs replacing?

Left and right are always viewed from inside the car, facing forward. Steering-wheel position does not change the vehicle side.

Left and right side selection guide with OE references 1820734-00-D and 1820735-00-D
LEFT SIDE · 1 PIECE

The vehicle's left fender.

Driver's side on a left-hand-drive car; passenger's side on a right-hand-drive car.

OE reference: 1820734-00-D

RIGHT SIDE · 1 PIECE

The vehicle's right fender.

Passenger's side on a left-hand-drive car; driver's side on a right-hand-drive car.

OE reference: 1820735-00-D

Each selection supplies one assembly. To replace both sides, add one Left Side and one Right Side to the cart.

HW4 side repeater camera, turn signal strip and molded fender housing assembly

One complete assembly

Camera.
Signal.
Housing.

The side camera, turn-signal light and molded outer housing come together as one replacement unit, with mounting features shaped for the existing fender opening.

Use it for a diagnosed failed camera, damaged repeater lens or broken housing. The vehicle wiring harness and installation tools are not included.

Keep the repair focused

Match the side.
Match the reference.

What arrives.

One selected side assembly, supplied as the camera, turn-signal light and molded housing shown. Order one of each side only if the repair requires both.

What the numbers mean.

1820734-00-D identifies the left application; 1820735-00-D identifies the right. Minor revision suffixes can change over time.

Accurate product status: this is a new aftermarket replacement offered by TESERY. The OE references identify the compatible applications; they do not mean Tesla manufactured the supplied part.

Use this part for a diagnosed failed camera, damaged signal strip or broken housing. A black camera feed or warning can also come from the connector, wiring or software. This replacement does not add HW4/AI4 capability or unlock Autopilot/FSD features.

Plan the installation

Fit. Reset. Recalibrate.

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.

Follow the vehicle-specific service procedure and complete the required manual-driving calibration before relying on affected driver-assistance features.

Calibration distance varies with road markings and conditions. Tesla notes that camera self-calibration can require up to 100 miles (160 km). Refer to Tesla's current service information for your exact model and region.

Why buy from TESERY

The right details.
Before you order.

A side choice you can understand.

Left and right options are named from the vehicle's point of view, with the relevant OE references shown beside each choice.

Support that starts with your car.

If your vehicle sits near a hardware change, send the vehicle year and a photo of the existing label through TESERY store chat. We will help confirm the application before purchase.

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 3.0 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.

If you encounter any issues after installation, please contact us before removing the product.
