Frequently Asked Questions: OE 15831815-00
This is listed against a long list of models. How do I know it fits mine?
This actuator fits a broad spread of models rather than one, which is why the fitment table on this page matters more here than usual. Find your own model and variant in that table before ordering, and treat the vehicle you actually have as the test rather than the name in the product title. The surest check is the marking on the unit already fitted to your car, which should read 15831815-00 or TA-3502310WXS. If your model is not shown, or you cannot read the old marking, send us your vehicle details and we will check it for you.
The number on my old actuator reads differently. What now?
That is common enough. The OE number for this actuator is 15831815-00 and it is also known as TA-3502310WXS, so either marking can appear on the unit fitted to the car. Get the old part clean enough to read and compare what is there against both of those references. If neither matches, do not assume the part has been changed at some point in the car's life. Send us the number you can read along with your vehicle details, and we will check it against the fitment table on this page before you commit to an order.
Does this need to be fitted by a professional?
Yes. This actuator is safety critical and belongs to the parking brake group, so it should go to a qualified workshop. There is no fitting procedure available for the BYD Sealion 05 EV, and we will not print one we do not have, so the garage should work from the vehicle manufacturer data for the model. Book the labour first and order the part around that booking. Give the garage the OE number 15831815-00 so they can confirm the unit they remove is the same reference.
How quickly does this actuator ship?
The delivery time is 8 to 25 days, from order to door. If the car is booked into a garage on a set date, tell us that date with the order so we can say whether it works. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 15831815-00.
What is the actuator made of?
This unit is made of metal and it is supplied New. It is listed as a motor drive assembly, so keep it boxed until the car is on the ramp and do not store it anywhere damp. Before fitting, hold it against the unit coming off and check that the OE number 15831815-00 matches what you can read there.
Where is this actuator mounted?
The mounting position for this part is the underbody. It is reached with the car raised rather than from inside the cabin, and it belongs to the parking brake and EPB group. This part is not split into a nearside and offside item. Confirm the position of the unit you are replacing before ordering, and check your own model against the fitment table on this page so you are matching the right part to the right car.
Why is there no second version of this actuator?
Only the Original/Genuine part from BYD is priced against this reference, so the page shows one option rather than two. There is no Aftermarket equivalent listed for it at the moment. That reflects what we have priced today and is not a judgement on the part. If you want us to look for an alternative reference for the BYD Sealion 05 EV, send the OE number 15831815-00 with your vehicle details through the quote route, and we will come back with whatever can be sourced against it.
