Frequently Asked Questions: OE 12840329-00
My old switch carries a different number. Have I got the wrong page?
Not necessarily. This item is known under HAD-3402400B-E1 as well as under the OE number 12840329-00, and the same switch is labelled more than one way depending on who printed the label. Check the string you can read against both references above before you draw any conclusion. If it lines up with either, you are in the right place. If it lines up with neither, do not order on a guess. Send us the number along with a photograph of the old part and its label and we will confirm it against the fitment table for you.
When will this steering wheel switch arrive?
Allow 8 to 25 days for delivery, counted from your order to your door. Order the part first and arrange any workshop time once it is with you. If the dates are tight for you, put the question through the quote route before placing the order. 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 12840329-00.
What is the switch set made from?
This part is made from plastic. It comes as a moulded switch set rather than as separate parts. If a single button on your car has stopped responding, this page supplies the set complete. Compare the button layout and the connector on yours against the images before you order.
Where on the car does this switch sit?
The mounting position for this item is the interior, and the description places it as a steering wheel switch set, so it is a cabin part rather than anything under the bonnet or beneath the floor. No left or right side applies to it, so there is a single version to order for a given car and no handed pair to choose between. Before ordering, look at how your own set is fixed and how many buttons it carries, then match that to the images and the fitment table on this page.
Is an Aftermarket version of this switch available?
Not at present. BYD is the manufacturer of the Original/Genuine version, and no aftermarket manufacturer is available under OE number 12840329-00, so there is nothing to show in a second tier on this page. What you can see priced here is the genuine item. That reflects what we are able to source rather than anything about the part itself. If you want us to go looking under the alternative reference, use the quote route with a photograph of the old part and its label and we will come back to you with whatever we find.
