Rear floor left closing panel for the BYD Qin PLUS DM-i, OE 18299117-00 (BYD HAD-5101390/70).

Supplied in grey primer as a genuine body repair panel, the rear floor closing plate welds into the original location to restore the floor section after damage.

Frequently Asked Questions: OE 18299117-00
How do I know this is the left side and not the right?
This listing is for the left side. If you are not certain that matches your car, look at the photographs on this page alongside the part you have taken off and compare the shape and where it sits. The left and right panels are mirror images of each other, so getting the side wrong means it will not sit in the underbody the way the old one did. Confirm against your own car before you order, using the OE number 18299117-00 as your reference point.
What if the number on my old part does not match 18299117-00?
No, do not fit this panel if the number stamped on your old part does not match either the OE number 18299117-00 or the reference HAD-5101390/70. Take the number from the part you are removing, the one physically stamped on it, and compare it directly against both references here before you order, rather than going by the car model alone.
How will a panel this size actually turn up at my door?
The delivery time is 8 to 28 days, from order to door. The packaging details are shown on this page. Before you place the order, take the old panel out and match it against the OE number 18299117-00, checking the number carefully rather than judging by eye, so what turns up is the panel your car actually needs and not one that only looks similar.
What is the rear floor left closing panel made of and does it matter for my BYD Qin PLUS DM-i?
It is metal, which is right for a panel fitted into the underbody structure of the car rather than a plastic trim piece. This one is listed in grey and comes new, listed under OE number 18299117-00, also shown as HAD-5101390/70. Before you order, take a look at your registration document and confirm the model and model year against what you have there, since that is the detail that decides whether this closing panel matches your Qin PLUS DM-i.
Does this panel need painting to match my car?
Beyond the grey finish it is supplied in, no painting or finishing details are given for this panel, so there is nothing here to say whether further finishing is needed. If you want to be certain of the exact specification before you order, check the reference HAD-5101390/70 that this part is also listed under, alongside the OE number 18299117-00, and compare both against what is on the old part you are replacing.
