Hello and welcome,
My name is ***** ***** it will be my pleasure to assist you today.
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
this is a coded part and requires programming upon replacement
sometimes you can get lucky and a used unit will work without coding, but I would not plan for this
programming can only be carried out with dealership-level equipment.
so, unless you know an individual or shop with such equipment and abilities, the dealer will need to do it.
In any event, you cannot avoide the need for specialized programming equipment to complete this step.
you may be able to find a non dealer with this ability on www.bimmershops.com or www.bimrs.org
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
