No fancy tools needed.
With the key in the off position, press and hold the 0.0 button
Turn the key to the "on" position
While still holding the 0.0 button, press the "min" button and the service light will be reset.
It's a little like a game of twister, but easily done.
To see miles remaining before service is due, with the engine off, turn the key to "on" then press and hold the 0.0 button. The trip will reset but KEEP holding the 0.0 and you will then see the miles remaining till service is due. KEEP holding the 0.0 and after about 5 seconds you'll see another number. I believe this is engine hours remaining till service is due.
When your done, let go of the 0.0 button and the trip odometer will return to the previous reading.
BTW this is for my 2009 Jetta 2.5 SE without the trip computer.
