In this video, we see that there are several ways to reset the service light on a BMW R1250 GSA: the simplest method is also the one that doesn't always work. We insert the key and turn on the ignition: we press and hold the partial tachometer reset button (located at the top of the left handlebar lever). While holding down the button, we wait to see the wrench symbol or the word "reset" appear. At this point, we release the button and then press it briefly to confirm the reset. The light should turn off. If the method doesn't work, we need to follow the system indicated in the video using an OBD tool, such as OBD Link LX, which can be found on AliExpress with the code 32966913053 at a price of 98.39 euros with free delivery. We will also need an Android App like "MotoScan" with a "pro" or "ultimate" license, at a one-time cost. We connect the adapter, turn on the system, connect the app, select the motorcycle, and perform the reset in the "instrument cluster" section, then select "reset service", from where the app will guide us through all the steps to reset all indicators and set the new maintenance interval. This is the best solution for DIY enthusiasts, as using the official GS-911 tool is very expensive.
