Side Impact Sensor for BYD e5 & T3, OE 12464479-00

This sensor fits more than one BYD model, so the safe check is the fitment table on this page rather than the title. Match your model and the build year, which you can read from your registration document, then confirm the OE number 12464479-00 against the number on the sensor you are replacing. The alternative reference M6-3658500-D1 may be what is actually printed on the old part. If your car is not in the table, or the entry looks close without being exact, use the quote route and send a photograph of the old part so we can confirm the match before you order.

Both are right. This part carries the OE number 12464479-00, and M6-3658500-D1 is an alternative reference for the same side impact sensor. The same part is often marked with the alternative reference rather than the OE number, which is why the two do not look alike. Write down whatever is printed on your old unit and hold it against the two references shown here. Where neither matches, do not guess. Send the marking and your model details through the quote route and let us check it first.

This part is safety critical, and it belongs to the airbags and SRS group, so the honest answer is to leave it to a qualified technician. There is no fitting sequence or test procedure published for this sensor, and inventing either would be worse than saying nothing at all. Give the garage the OE number 12464479-00 and the alternative reference when you book the car in, so the part on the bench can be identified against the one coming off before any work starts.

The delivery time is 8 to 25 days, from order to door. Both are shown against the item on this page. If the car is off the road, say so when you use the quote route and we will tell you what the position looks like for your model before you commit. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.

Plastic is the material for this side impact sensor. Nothing else about the moulding is specified, so we make no claims about its grade or finish. If the old unit on your car looks physically different in shape, check the fitment table on this page and the OE number before ordering.

There is a single tier here because no aftermarket equivalent exists for OE number 12464479-00. What you see is the Original/Genuine part from BYD. Where two tiers exist for an item, both appear on the same page and are priced there, so one tier is a statement about availability and nothing more. If you have been quoted an alternative part elsewhere, put its reference into the quote route along with your model and year and we will look at whether it can be matched.
