The dealer shipped a replacement switch (part #61-31-6-997-300) and it did not function at all. Then I reinstalled the first switch they sent and it functioned, less the led light illumination. I then carefully removed the top cover of both switches they sent and discovered on the first one that the LED was not centered in the hole so it would not appear to illuminate with t cover in place even though it was illuminated. I bent the LED so that it would align with the front cover hole, problem solved. The second (replacement) one had a different circuit board number yet the switches had the same BMW part number. Conclusion, this is a hit or miss so make sure you can return it if non functioning. Hope this helps!
