"Service Engine Soon" Light - turn off

I have a 2005 Z4, 2.5 with 55,500 miles on it. The 'service engine soon' light just came on. I presume this is in anticipation of 60,000 service. Other than taking to the dealer for service, does anyone know how to turn off this message light?

You should have the error codes read to determine the fault and have the proper repairs done. You could damage you car if you keep driving with the light on. It has nothing to do with the 60k service. Have you read the owners manual?

It says:
Exhaust emission values
The warning lamp lights up: the
exhaust emission values have worsened.
Have the car checked as soon as possible.
The lamps flash under certain conditions. This
indicates excessive misfiring of the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.

If someone does their own service how, then, is the service light reset?

1) With engine off and key not inserted keep pushing the left button on the instruments cluster ;
2) Insert key and turn to position 1 (do not leave the previous button) ;
3) Wait about 5 seconds (button alway pushed) until the service will show on the display ;
4) Leave the button for a moment and then push it again until the rESET on the display will start flashing ;
5) Now release the button and quickly push it again when rESET displays when flashing

Thank you. I don't remember seeing that information in the owners' manual. Is it in the service manual?
