Front Impact Sensor I for BYD M3 & S2, OE 12464503-00

You have. This Front Impact Sensor I carries OE number 12464503-00, with TA-3658300-D1 as an alternative reference for the same part. One part, two numbers. Check the marking on the old sensor carefully and match it to one of the two references printed on this page, taking every character rather than the first few. If what you are holding matches neither, stop there and send the marking with your model and year through the quote route so the right part can be identified before you order.

Yes. This part is safety critical and belongs to the airbags and SRS group, which is not an area to work on by feel. A qualified technician with the manufacturer's procedure for your model should do the job. We deliberately publish no fitting steps here, because none exist for the part and guesswork on restraint components is not something we will put in writing. When you book the work, quote OE number 12464503-00 so the garage can confirm the part before the car is stripped.

Delivery takes 8 to 25 days from your order to your door. Neither is a fixed calendar date, and both are printed on this page so you can check them against the timing you need. If you are holding a ramp booking, ask through the quote route first and order with a margin rather than to the day. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.

Plastic is the material for this sensor. A plastic body is worth keeping boxed until the technician wants it on the bench. There is no further material detail available, and we will not fill the gap with assumptions. Compare the shape with your old unit using the images and the fitment table on this page.

This sensor mounts in the engine bay, towards the front of the car. That is as precise as we can be, so we will not describe the exact bracket or the route of the loom. The workshop information for your model covers that, and the garage doing the work will have it. Before ordering, use the fitment table on this page to confirm your model and year, and check OE number 12464503-00 against the marking on the unit that comes off the car.

Because no aftermarket equivalent exists for OE number 12464503-00. The item shown is the Original/Genuine part made by BYD. When an aftermarket version does exist for a part, it appears alongside on the same page, so the absence here simply reflects what can be sourced. If you have found another reference that is said to fit, send it with your model and year through the quote route and we will check it.
