Frequently Asked Questions: OE 12581809-00
Is this the left or the right rear regulator?
This one is the left rear unit, mounted in the rear door on that side. Left and right are called from the driver's seat looking forward, so the side does not change with where the steering wheel sits. The quickest way to be certain is to take the door card off and read the number on the fitted regulator, then check it against OE 12581809-00. If your car needs the other side, that is a separate listing under its own OE number.
The number on my old regulator is not 12581809-00. Is this still the right part?
It can be. Besides the OE number 12581809-00, this regulator is also known as EL-6204100. Suppliers and repairers use both, and a label carrying the second reference does not mean you have a different component in your hand. Clean the old unit and read every number printed or stamped on the body, including anything on a sticker. If one of them matches either reference here, you are on the right listing. If neither matches, send the numbers you can read through the quote route on this page and we will check them for you.
When will this regulator arrive?
Allow 8 to 28 days for delivery, counted from your order to your door. If you need the car back on the road sooner than that, say so through the quote route on this page before you order, so the timing can be confirmed against the current position. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12581809-00.
What is this regulator made of?
This regulator is made of metal. In practical terms it arrives rigid, so it wants to be kept flat and supported when you lift it out of the packaging instead of being bent to clear the door aperture. Line it up carefully against the fixing points rather than forcing it into place. Metal will mark if it is dragged across a painted edge, so protect the door skin while the unit is going in. Check the OE number against the old regulator before you order, to confirm it matches your BYD e3.
Why is only one version of this regulator offered?
Only the Original/Genuine version is listed for this one. The manufacturer for it is BYD, and no Aftermarket equivalent has been sourced and priced for this OE number, so there is a single option on the page instead of two. That reflects the supply position and says nothing about the part itself. If you would rather be quoted on an alternative, ask through the quote route on this page with OE 12581809-00 and the details of your car, and you will be told what can be found.
