Hi anyone out there know how to reset the service spanner on a mk3 micra, 1st told it had to go onto the machine, then had a word with a Nissan tech. who said bring it down, I'll do it for you now. I said i thought it had to go on the computer, no was the reply, I'll just do it outside. Any help would be appreaciated.

On French cars pushing and holding the trip reset button while switching on the ignition usually does the trick. (Does on mine, anyway!)

That's the most common way to reset a service indicator on a wide range of cars.
