How to Reset the Service Light on a Volkswagen Passatby Jody L. Campbell
Some Volkswagen dealers would have Passat owners thinking they need to bring their cars to them for oil change services or purchase a special tool to reset the "Service" light illuminating on the dashboard. This is a mileage interval light that trips every 3,000 to 5,000 miles that indicates an oil change is necessary. You do not need a special tool to change your oil, nor do you need to bring the car in to the dealer.
Sit in the driver's seat of the Passat and close all the doors.
Position the trip/odometer button to display the odometer mileage reading, then hold it down with the forefinger on your left hand.
Turn the ignition key to the "key-on/engine-off" position to turn on all the power options for the Passat without actually starting the engine. At this point, a service indicator light will display (in the form of a wrench).
Press the minute adjustment button on the clock (or turn the knob clockwise on European manufactured Passats) and release the trip/odometer button.
- On 2007 and newer Passats, there are some that have a "wrench button" to the right side of the trip reset. You would hold this button down instead of the trip/odometer, turn the ignition key to the "key-on/engine-off" position, release the wrench button and press the "min" (minute adjustment) button on the clock to reset.
