Frequently Asked Questions: OE 18321112-00
How do I know this is the left sill panel and not the right one?
This listing is for the left side, fitted in the engine bay area of the BYD Yuan PLUS. Before ordering, check the OE number 18321112-00 against the number on your old panel, since the alternative reference EM2E-5101251Q/77 may also appear stamped on the original part. If you want the fitting confirmed against your specific car, use the quote route on this page and give your vehicle details there. That way the side is checked before the order goes through, rather than after the panel has arrived.
Why does this only fit one model and what if mine is close but not exact?
No other model is shown against this OE number, only the BYD Yuan PLUS. If your own car is a similar model, do not order on that basis alone. Check the side, the position on the body and the fixings on your own car against the part before you buy, since a close model is not the same as a matching one. That comparison, done before you order, is the only way to be certain the panel in front of you is right for the sill you are replacing.
What do I do if the number on my old panel does not match this one?
If the number stamped on your old panel does not match 18321112-00, do not fit this one anyway. Find and read the number on the part you are taking off the car, since that is the figure that decides whether this is the right replacement, not the model name or the year of the car. Write it down exactly as it appears, including any letters, and compare it directly against this OE number. If the two still do not agree, hold off ordering until you have checked further, rather than guessing and hoping it fits.
How is a part this size actually delivered to me?
The packaging details for this panel are shown on this page. Delivery time is confirmed with your quote. You can also check this part against the alternative reference EM2E-5101251Q/77, which is a quick way to confirm you have the right item before it arrives. The shipping cost is confirmed with your quote.
What is the left sill inner panel made of?
This is a metal panel, new and not a reconditioned part, made to fit the BYD Yuan PLUS on the left side of the engine bay. Being metal, it holds its shape under the trim and fixings around it rather than flexing like a plastic moulding. Match the OE number 18321112-00 against the number stamped or marked on the panel you are removing before you order, since the alternate reference EM2E-5101251Q/77 may appear on some listings for the same part. Check the fitment table on this page to confirm it suits your specific build.
