Re: turning off service light on dashboard 850 93

Well. I found out about this on this brickboard in the past.

I guess it is my turn to tell you how to do it.

There are two diagnostic units(it says A and B on the cover)

located adjacent to washer reservoir under the hood.

Turn on the ignition and open the module A and insert the flylead

into socket 7. Press the button on the diagnostic unit 4 times,

briefly but firmly. Then the LED illuminates and stays illuminated,

and the system is ready to accept manual code input.

A code number for resetting the service reminder light is 1-5-1.

To do this, press the test button once and release it.

And LED illuminates again. then press 5 times and wait for the

LED to illuminate. Press the button once and LED should

flashes several times in succession and the reminder should have

been reset. Switch off the ignition and replace the flylead in its

holder and close the cover.
