BYD ADAS sensors: which parts are orderable, and why replacement is not the whole job

Driver-assistance hardware generates a particular kind of ordering mistake. A car comes in with a damaged sensor area — a broken cover, a cracked bracket, a unit knocked out of position — and the order that goes out is for the sensor. What arrives is one component of a set. The brackets, the cover, the retainers and the sealing pieces are separate lines in the catalogue, and they are the lines most often left off the order. Then a second problem appears, which is not a parts problem at all: after ADAS-related parts are replaced, the system typically requires a calibration or a learning procedure on diagnostic equipment. That belongs with a workshop, not with a parts supplier. This page is about the first half of that — what is purchasable, what gets forgotten, and why the VIN decides the number. No calibration procedure, no sequence, no condition and no value of any kind appears on it.

1. What "ADAS parts" means on an order

The term covers more hardware than buyers expect, and the hardware does not arrive as a kit unless the reference says it does.

Read down the third column and the shape of the problem is obvious: the one line everybody orders is the one line nobody forgets. Everything else in the set is a candidate for a second order.

2. The mistake: ordering the sensor without the mounting set

Two assumptions cause it. The first is packaging — the belief that a sensor arrives with the bracket it sits in and the cover that goes over it. In this catalogue it generally does not, and there is direct evidence for that in our own index: Sensor Fitting And Protecting Elements 13246638-00 and Sensor O-Ring 10500252-00 are listed as their own lines rather than being folded into the sensor reference. If the fitting around a sensor is a separate line in the data, the bracket and cover behind it should be treated the same way until a reference proves otherwise.

The second assumption is cosmetic. A cracked cover or a broken bracket looks like trim, so it gets ordered as trim, late, after the sensor. But the cover and the bracket are not decorative in this context: they are what holds a sensing unit at the attitude it was calibrated at, and they are what the unit sees through. Substituting a look-alike part from a different trim level is not the same as fitting the right one.

The cheap way to avoid both mistakes is to build the enquiry as a set. List the sensor, the bracket, the cover and any sealing or retaining pieces on the same request, with the VIN, and let the numbers be confirmed together. Bundling them into one consignment costs nothing extra on your side and removes a second round of questions when the car is already on the ramp.

3. Calibration is a separate matter, and it is not a parts question

This is the part of the job buyers most often discover late, so it is worth stating plainly.

When ADAS-related parts are replaced — a sensing unit, a bracket, a cover, or the trim in front of a sensor — the system will typically require a calibration or a learning procedure on diagnostic equipment afterwards. That is a workshop task. It needs the right equipment, the right environment and technicians qualified for it. It is not something a parts order can cover, and it is not something this page describes: no procedure, no sequence, no condition and no value appears here, and nothing on this page should be read as one.

What that means for purchasing is narrow but real: the cost of a driver-assistance job is not the cost of the component. A workshop quoting the work needs to know that the part is one line of several, and that the post-replacement procedure sits outside the parts supply entirely. Buyers who plan the order as a set and confirm the VIN first do not discover the second step after the first box arrives.

4. What our own index shows

Our index carries the sensing and fitting layer rather than a separate "ADAS" category, and the pattern there is the same one that runs through the whole BYD catalogue.

In our own data we see four references under Abs Sensor and three under Sensor, Coolant Temperature, and the published index carries no fitment column. Two consequences follow. Wheel-speed sensing is handed by definition at the corner and the index does not print side, so the number plus the VIN is the only safe route; application confirmed per enquiry against the OE number and the VIN. And within any one family, neighbouring references are not substitutes — 13640051-00 and 13640918-00 share a name and nothing else that we can see.

The dispersion is the argument for number-first ordering on driver-assistance work specifically. This is the category where a wrong number is most expensive to absorb, because the part arrives, the trim goes back on, and the discrepancy surfaces at the calibration step rather than at the goods-in desk.

5. Why the VIN is mandatory on ADAS work

Driver-assistance equipment is specification-dependent to an unusual degree. Two vehicles of the same model can carry different sensor suites, different camera positions and different exterior trim in front of them, and the differences are trim-level differences rather than model-year differences that a name would reveal. Add the naming situation — the same vehicle is marketed in Europe under more than one designation, and bodies are shared across models sold as Dolphin, Atto 3, Seal, Seal U, Sealion 7, Tang and Han — and the model name alone is not a specification for anything in this category.

So the VIN is not a formality here; it is the only thing that identifies the build. Send it with the first enquiry, alongside the number read off the old part or a photograph of its label, and state whether the vehicle has the driver-assistance equipment the enquiry concerns.

6. What to send

The VIN, which fixes the build and the equipment level. The OE number from the old part including the -00 suffix, which is part of the identifier in this format. Photographs of the part, its label and the surrounding trim, because a cover or bracket is identified as much by what it sits against as by its own shape. And the full set — sensor, bracket, cover, retainers and any sealing or protecting pieces — so the whole list can be confirmed in one pass.

We confirm, part number by part number, whether we can supply it. Minimum order value is €50 per shipment; guide prices are shown on the parts pages, and trade and volume pricing on request. Typical dispatch time is confirmed on the quotation; transit depends on the shipping method you choose. If the line you need does not appear in the published index, send us the part number or a photo of the label, and we will check whether we can source it. Browse the electrics and sensors category, start from the BYD-compatible parts — OE reference index, or use the enquiry page.

Short answers

Can I order just the sensor? You can, but it is rarely the whole job. Brackets, covers, retainers and sealing pieces are separate lines — Sensor Fitting And Protecting Elements 13246638-00 is listed on its own in our index, which is the pattern to expect.

Does the sensor come with its bracket and cover? Treat them as separate until a reference says otherwise. Ordering the set in one enquiry is free and avoids a second round when the car is already on the ramp.

Is calibration needed after these parts are replaced? Typically yes — a calibration or a learning procedure on diagnostic equipment is normally required after ADAS-related parts are replaced. It is a workshop task for technicians qualified for it, and this page does not describe it.

Why are there four Abs Sensor numbers in your index? Because wheel-speed sensing runs across the range and our index carries no fitment column to separate the references. 13063067-00 and 13089079-00 share a name; we do not assume they share an application.

Do I really need the VIN? Yes. Driver-assistance equipment varies by trim level, and the model name does not reveal it. The VIN is what identifies the build.

Will you publish the calibration procedure? No. This page covers parts identification and purchasing only, and it carries no procedure, no sequence and no values.

Where this comes from.

The references and group counts quoted above are taken from GNSGO's own parts index for BYD vehicles — the same list at BYD-compatible parts — OE reference index. Application is confirmed per enquiry against the OE number and the VIN; the published index does not carry model-year fitment, so we do not infer it here. Model names follow the export designations listed for this project, and we do not assert naming relationships beyond them. We have not drawn on BYD's copyrighted workshop documentation, and we do not reproduce any manual or wiring-diagram pages. Where our own data does not carry an answer, we say so rather than filling the gap with a plausible one.

This page is general information only. It is not a repair instruction, not a diagnosis of a particular vehicle, and not a substitute for professional advice. Restraint-system and high-voltage parts are outside the scope of this page. Work on high-voltage systems, restraint systems and structural repairs belongs with technicians qualified for it. Confirm the application against the VIN before ordering. Have any work carried out by a suitably qualified workshop.
