Hey guys I'm going to be tearing off my bumper this weekend and replacing what I assume is a bad xenon control module from moisture in the headlight and resealing it. I'm aware that the M3's did not get the LCI headlight upgrade but I'm seeing two types of ballasts that both say they fit my 2012 M3 with adaptive headlights.

This is what I already ordered - https://www.ebay.com/itm/262368841626

After looking around I noticed there's also this one with an additional 01 at the end of the number that also supposedly fits my model - https://www.headlightexperts.com/hea...xoCfbUQAvD_BwE

This video at 6:33 says you need the one with the 01 at the end or it won't power the lights. - https://www.youtube.com/watch?v=HqYYPFRohV4&t=431s

Some of the guys on the e9x m3 facebook page are saying I need the one I already purchased without the 01.

Anyone have any knowledge on this?
