How to Reset the Service Light on a BMW 3 Series G20/G21

Model: BMW Serie 3 G20 - Years 2019-2026
Part: Service warning light

Resetting the service light on a BMW 3 Series G20/G21 requires access to the diagnostic menu. Turn on the ignition without starting the engine, and press the start button three times in a row, then hold the "BC" button (on the outer edge of the wiper lever), or the "0.0" button on the dashboard - depending on the trim - until the display shows "Diagnose mode active". In the menu, select "engine oil" and hold BC to reset the oil. The display will show the new interval. For the brakes ("Bremsbeläge" = pads), the reset is only possible after replacing the pads and wear sensors. If the sensors are still old, the system prevents the reset. After replacement, repeat the procedure to reset the brakes as well. Exit the menu by turning off the ignition. The procedure is simple, but it requires that the components be actually changed before the reset.

How to Remove the Front Bumper of the Citroën C4 Picasso?

To remove the front bumper of the Citroën C4 Picasso, you need to take out all the rivets and screws that secure the piece to its housing: these screws are located inside the wheel arches of the front wheels and at the central upper part of the bumper itself. Once all these fastening elements have been removed, you can detach the bumper from its seat by disconnecting the connectors inside and then insert the new replacement part. The new part can then be secured and connected properly, ensuring it is correctly fixed in place.
