When a single worn part costs $110.99 and a replacement device costs many times that, the answer is usually a part swap — but not always. This guide gives the decision criteria, using the parts listed for DRL Boards FOR 2014-2017 BMW M3 M4 430i 440i 428i 435i Xenon (4 variants) as the working example.
DRL Boards FOR 2014-2017 BMW M3 M4 430i 440i 428i 435i Xenon: Compatibility
The compatibility string on the listing names DRL Boards FOR 2014-2017 BMW M3 M4 430i 440i 428i 435i Xenon verbatim. Closely named models in the same family are the main source of wrong orders, so read the model printed on your device (usually on a sticker or in the device's app/settings page) and match it character for character — "Pro", "Plus", "Ultra", "XL" and revision suffixes all matter.
