Original BMW Turn Signal and High Beam Combination Switch for BMW 128i, 135i, and 135is (2008–2013)

Turn signals and the high and low beam headlights on the 2008–2013 BMW 128i, 135i, and 135is are operated through this Original BMW steering column switch unit, part 61-31-9-123-041. The combination lever sits on the steering column within easy reach of the driver's hand. Its turn signal function switches on the left or right blinker to signal a turn or lane change. BMW sells the unit as a single piece.

Original BMW Parts carry a 24-month parts warranty.

BMW released this unit in September 2007 as the replacement for 61-31-9-110-886 and rates the change as exchangeable retrospectively, so it goes into 1 Series cars built with the older number. On the engine side, BMW's data ties it to the 128i with either the N52N or N51 and to the 135i with either the N54 or N55. Because one switch unit spans all four engines, the engine code does not change which switch you order within this fitment.
