Hi everybody. Firstly nice to meet all of you. I was recommended to this forum by a friend who used to post on here when he had a BMW. I have had my 320d 3 series e90 (06 plate) for about 6 month. Due to going through my mid life crisis this is the first bimmer. Love it and no major problems as of yet. The service light come on today which after watching a few clips on YouTube, I felt confident to clear them myself. The first one was air con which I managed to reset. The last one was the back brake sensor service but when I reset it come up with --------- it was as if it wanted me to input mileage to let it clear. After an hour of trying I gave up. Am I completely wrong in my assumption? Many thanks in advance.
