Side Impact Sensor for BYD e3 & e2, OE 12458489-00

This sensor fits a fair spread of BYD variants, so the badge on the boot lid is not enough on its own. Use the fitment table on this page and find the row that matches your exact build and year. Then compare OE number 12458489-00 with the marking on the sensor already in the car, if it can be reached safely. Airbag and restraint components are not parts to order on a guess. If your build is not in the table, send us the vehicle details through the quote route first.

The marking on your old sensor may read M6-3658500A-D1 rather than 12458489-00. Both belong to this same item, so either one confirms you are in the right place. If what you can see matches neither, do not order against a similar looking number. Send us the characters you can read together with your vehicle details through the quote route and we will check them against our fitment data. With an airbag system component it is better to lose a day checking than to fit the wrong reference.

Yes, and firmly so. This sensor is safety critical and belongs to the airbag and restraint system, which is not an area for work at home. No fitting procedure or wiring detail is provided for it, and we will not supply either from elsewhere. Book it with a qualified technician who can follow BYD's own procedure for your model, handle the system safely while the work is done, and confirm afterwards that no fault remains stored in the car.

The delivery time is 8 to 25 days, from order to door. Book the workshop time from the later date. The packaging details are shown on this page. If your car is in for restraint system work and the timing has to be pinned down, ask us through the quote route before you order and we will tell you where things stand.

This sensor is plastic bodied, coloured blue, and supplied new rather than reconditioned. Leave it sealed in its packaging until the technician actually has the car open, because a plastic housing that has been knocked about in a toolbox is worth nothing to anybody. Hand it over still wrapped, along with the OE number 12458489-00, so the technician can check it against what is coming out.

This sensor is offered in one version only. Nothing is listed at the Aftermarket tier against 12458489-00, so the Original/Genuine BYD part is the entire offer on this page. Where a second tier exists for a part, both appear together and you choose between them, but that does not arise here. If you would like us to look for another supply route to the same reference, send your vehicle details through the quote form on this page and we will tell you honestly whether anything is available.
