BMW 5 Series brake pad warning light reset method: 1. Turn on the ignition, press the reset button for 8 seconds until the multifunction display shows the oil symbol, then press again to display the rear brake pad system reset; 2. Select the option that needs to be reset, press and hold the reset button for 3 seconds, the display will show 'reset', then press the reset button again until the display shows 'OK', then turn off the ignition. Taking the BMW 5 Series 2021 525Li M Sport Package as an example: This car is a mid-to-large-sized vehicle under BMW Brilliance, with a gasoline energy type and meets the China VI emission standard. In terms of power, the car is equipped with a 2.0T turbocharged engine, model B48B20C, and an 8-speed automatic transmission. For the suspension system, the front suspension is a double-wishbone independent suspension, and the rear suspension is a multi-link independent suspension.
After driving for so many years, I've learned that resetting the brake warning light on a BMW 5 Series requires professional tools. After installing new brake pads, you need to connect to the OBD diagnostic port and use BMW's dedicated ISTA or third-party devices like OBDeleven to perform the operation. In the APP, proceed to reset the brake system warning. Remember to check the sensors—if they're excessively worn, they need to be replaced; otherwise, the light won't turn off. Don’t overlook brake disc thickness during regular maintenance; replacing brake pads every 30,000 kilometers is a hassle-free approach. I recommend going to a 4S shop or an experienced garage to ensure accuracy, as improper handling could affect the ABS function and compromise driving safety. DIY attempts are too risky and could easily disrupt the electronic systems.
I'm a hands-on amateur car mechanic. Resetting the BMW brake warning light isn't actually difficult, and I often use an OBDeleven scanner. After installing new pads, plug it into the car's OBD port, open the app, and select fault code clearing. The key is to ensure the brake sensor status isn't loose. If it fails the first time, don't panic—just check that the wiring connectors aren't corroded. To save money, you can buy the tools yourself for around a hundred or two, but tire shop labor services are also reliable. Brake fluid should be changed regularly too—safety first.
