How do you reset service light manually on a 2004 525i?

Answer 1

Turn the key ON (all the way) but do not start the car. Press and hold the trip reset button for about 10 seconds and the central display of your instrument cluster will first show you the oil service, release the button, press and hold it again and the word "reset?" will appear, release the button and press it again until it shows"----", relaese the button at that moment and let the car recalculate the new value. Once it shows the new mileage value of the next oil service, press and release the button again and it will take you the front brakes and so on. Repeat the above procedure for each component. The order of the menu is the same as the one showed on the navigation display (under the menu Service). Note that it is not recommended to reset the brake pads (front and rear) especially if there's less than 2000 miles left as the computer might drop its "due" mileage to a negative number of -9000 miles. That car has a brake pads thickness self-monitoring system and will re-calculate the mileage left based on the actual thickness but it might stay on a negative mileage until you change the brake pads. If after this (after you changed the brake pads) you still can't reset it then you need to take it to somebody who has a GT-1 (BMW original computer) to reset it. You will save 1000s of dollars if you do this yourself. Have fun. Visitor
