There’s no great ”trade secret” as to how to reset the service indicator lamp on most VW’s, simply refer to pages in the Owner’s Handbook!
For reference of those interested in such matters, but who might not have access to an owner’s manual, this is the procedure to follow:
Note: the Service Reminder Indicator displays 3 messages: OEL, IN 01, and IN 02. These display to alert the driver to follow the items listed under the manufacturer’s service interval.
To reset the message displays, turn the ignition switch on. Press and hold the odometer reset button “A” located below the speedometer. Turn off the ignition while holding the button. “OEL” will display on the indicator. Press and hold the lower digital clock reset button “B” until five dashes appear in the display. If needed, press the odometer reset button until “IN 01” appears and then press the clock reset button until five dashes appear. If needed, press the odometer reset button until “IN 02” is displayed and then press the clock reset button until five dashes appear.
To exit reset mode, turn the ignition switch on and when “IN 01” appears, turn the ignition switch off.

To the best of my knowledge, the above service light reset procedure applicable to most Volkswagens
1. To reset MAINT reminder light after engine oil replacement, turn ignition switch to OFF position with odometer showing ODOMETER READING. Turn ignition switch to ON position while holding down trip meter RESET button.
2. Hold trip meter RESET button down for at least 5 seconds until odometer indicates “000000” and MAINT reminder light goes out.
