Dear customer, in these 420 models when it comes to locating spare parts there is a problem, because BMW just made 420 models until March 2015, just in March 2015 the new models arrive, but it is not difficult to solve in your case, because as it is an external part, simply by observing visually you can determine which is the exact replacement for your 420, If you already buy the parts, and you need more help please let me know.
My goal is to give you the best advice i can based on your description, I hope to be helpful, if you have any doubt please do not hesitate to reply back.Kind regards, Sebastian.
Dear customer, I really agree with you, if the fuses are correct and the light bulb is correct, the only thing that is necessary is a diagnosis to check the status of the control module, but if you do not have diagnostic access, I do not recommend spending unnecessary money on the diagnosis , locate a tester or multimeter and place it from the connector to check if there is indeed electrical signal in it and if there is, it directly replaces the headlight.
