About This Part
This engine sound simulator is the external speaker that generates the low-speed pedestrian warning tone required on electric BYD models, fitting the Sealion 05 EV (2025-2026), Seal 05 DM-i (2024-2026) and 2nd-Gen Qin PLUS DM-i (2024-2025). Listed under OE 16059371-00 and reference HC2EA-3778020-W3, the sealed unit mounts by its two flanged tabs and connects through the moulded plug. Often called an AVAS speaker or acoustic vehicle alerting system, it plays the synthesised drive sound at low speed. Bolt it in as a direct replacement for a silent or faulty unit.

Frequently Asked Questions: OE 16059371-00
My old unit has a longer number on the label. Is this the same part?
It can be. The OE number for this one is 16059371-00, and the alternative reference we offer is HC2EA-3778020-W3. If the label on your old unit carries more than one code, compare each of them against both of ours rather than stopping at the first. Length alone does not tell you which code is the reference. Write down everything printed there before the old unit is thrown out. If you cannot match either, send us what is printed on it together with your vehicle details through the quote route on this page and we will identify it.
How quickly can this be sent out?
The delivery time is 8 to 25 days, from order to door. We would rather answer that in advance. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the OE number on your old part against the one on this page. If anything about the timing matters for a booked repair, ask through the contact page.
What is the housing made from?
This part is plastic and supplied new. Keep it in its packaging until the fitter is ready, and handle the connector end carefully when you do unpack it. Coding or setup once it is fitted to the car is not covered here, so ask your workshop about that before the car is booked in.
Where is this unit mounted?
The mounting position for this unit is the engine bay, so it is reached with the bonnet up rather than from inside the cabin. It belongs to the infotainment and instruments side of the catalogue rather than to anything mechanical. Which bracket carries it or how the loom reaches it is not described here, so we will not describe the fitting itself. Somebody who works on the model regularly will know where to look. Check the fitment table on this page against your own vehicle before you order, and keep the OE number 16059371-00 with the job sheet.
Why is there no second version to choose from?
Only the Original/Genuine part is offered here, and the genuine manufacturer is BYD. No Aftermarket equivalent has been sourced for this OE number, so the page carries a single item at a single price. On parts where both tiers exist, they appear together and you pick the one you want. This one has not been duplicated, and if that changes the second tier will be added to this same page. If you want us to look for an alternative reference now, use the quote route on this page.
