Frequently Asked Questions: OE 18299123-00
Is this the left or right side panel?
This is listed as the left side. Before ordering, sit in the car and work out which is left and which is right as you face forward in the driver seat, not as you look at the car from outside. Check the position of the panel behind the front door on that side and look at the fixing points on your own car to be sure they match before you commit to this one.
The number on my old panel does not match 18299123-00, what now?
Look for the number stamped directly on the reinforcement panel you are removing, rather than relying on a workshop manual or invoice. That stamped number is the one to compare against the OE number listed here, 18299123-00, or against the alternative reference HAD-5401260/70. If neither matches what you find on the car, do not fit this panel. Use the quote route on this page and send over what is stamped on the old part so it can be checked properly before you order.
How will a panel this size actually reach me?
The packaging details for this panel are shown on this page. Delivery time is confirmed with your quote. Before you order, open the fitment table on this page and match it against the BYD Seal 05 or Qin PLUS you are working on, so the panel that turns up is the one your car actually needs. The shipping cost is confirmed with your quote.
Is this panel metal or some kind of plastic composite?
It is metal, which is why it is treated as a structural body panel rather than a trim piece. Have your registration document to hand and check the model and model year shown there against the fitment table on this page before ordering. This part is listed for the BYD Seal 05 and Qin PLUS, so matching the year on your document to the listing keeps you on the right one.
