The method to reset the maintenance light on a BMW 520 is: 1. Turn off the ignition switch to shut down the engine, then press the button at the lower left corner of the instrument panel; 2. Turn on the ignition switch to light up the instrument panel; 3. Hold the button at the lower left corner for 5 seconds; 4. Release the button and press it again for about 5 seconds; 5. Release the button and hold it once more to display the new maintenance interval; 6. Press the button until the word "ENDSIA" appears. The BMW 520 is a 4-door, 5-seater mid-to-large-sized sedan with exterior dimensions of 5106mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 2888mm. It is equipped with a 2.2L naturally aspirated engine and a 6-speed automatic transmission, delivering a maximum power of 125 kW and a maximum torque of 210 Nm.

As someone who frequently tinkers with cars, I'm quite familiar with resetting the BMW 520 maintenance light. The basic method is: First, park the car and turn off the engine, insert the key into the ignition position but don't start the engine. Then hold down the ODO button on the dashboard without letting go—that's the small button that displays the mileage. Next, turn the key to the ACC position to power up the dashboard, and you'll see the maintenance light start flashing. Wait about 5 seconds, release the ODO button, and immediately press and hold it again for 5 seconds until the light goes out—that's it. From my experience, there are slight differences in BMW models from different years. For example, older 520 models might require checking the button position, while newer ones might have simpler operations via the central control screen. A safety tip is to do this in the garage; don't attempt it while driving, as it's easy to get distracted and make mistakes. If it doesn't work the first time, try a few more times or check the user manual—better safe than sorry. Remember, after resetting, the maintenance cycle starts anew, so don't exceed the mileage without servicing.

I've been using a BMW 520 for many years, and the maintenance light reset operation is actually not difficult. Usually: After turning off the engine, hold the ODO button, turn the key to the ON position but don't start the engine, wait for the maintenance light to flash, release the button and immediately hold it again for a few seconds to confirm the reset, and the light will go off. The whole process takes a minute or two, the key is to hold the button steady and not release it too early. I think it's easiest to do it right after maintenance, so you don't have to deal with the annoying light. Safety reminder: don't try it while driving, find an open space and take your time. If there's no response, it might be due to poor button contact or system delay, just try again. If it still doesn't work, refer to the manual or go to the 4S store for peace of mind. After all, BMW systems are quite sophisticated, so don't mess around and cause unexpected faults.

The method to reset the maintenance light on a BMW 520 is quite straightforward: After turning off the engine, hold down the ODO button without releasing it, turn the key to the ACC position, wait for the light to flash, then release the button. Next, press the ODO button again for a few seconds until the light goes out. The entire process is simple and quick, just make sure the buttons are pressed firmly and the key is in the correct position. If the reset doesn't work, checking the manual or directly consulting a professional mechanic is the safest approach—don't force it to avoid causing issues.
