Frequently Asked Questions: OE 12278356-00
Which side is this trim panel for?
The right-hand side, and specifically the front door B-pillar on that side. Right means the offside as you sit in the driver's seat of a right-hand drive car looking forward. The panel is shaped to its own pillar, so it will not turn round and serve the opposite side. Stand at the car and identify the pillar between the front and rear doors before you order, then check the fitment table on this page. The left-hand equivalent is a separate listing under its own OE number.
What if my old trim shows HAD-5402840-00BX?
Then it is the same panel. The marking on a trim panel is usually on the reverse, near a clip, so you will only see it once the panel is off the pillar. Read the full string including the suffix, because the suffix is often what separates one finish from another. Anything you cannot match should go through the quote route with a photograph of the old part and its label.
When can I expect this trim panel?
Delivery takes 8 to 28 days from your order to your door. Plan the bodywork around those dates. A missing pillar trim leaves the car usable in the meantime, which gives you room to order both sides together if the other one is also marked. If a body shop slot is already booked, put the date to us through the quote route before you order.
What is this trim panel made from?
Plastic. The panel is long, in keeping with the length of the pillar it covers. Store it flat and on its own until fitting, since a long plastic panel will take a bow if it is leant against a wall for a fortnight. Keep the protective wrapping on the visible face while you offer it up, and only remove it once the clips have taken along the full length.
Does this panel need painting to match the car?
No. It is supplied in piano black, a gloss finish that is meant to be seen, and it mounts on the exterior of the pillar where everyone will look at it. That finish is the same across the cars it is listed for, so there is no body colour to match and no paint work to arrange. Do not attempt to lacquer or polish it before fitting. Handle it by the edges, keep it wrapped until the last moment, and check the fitment table on this page first.
Is this trim available at a second price level?
No. Only the Original/Genuine panel made by BYD is offered for this trim, so the page carries one tier and the price shown on this page is for that part. Where a part has an Aftermarket version, both appear together and you pick between them. For a gloss exterior panel there is often no equivalent to offer. If you want us to look anyway, send the OE number 12278356-00 through the quote route and we will tell you what is out there.
