The "Service" lamp lights up in my 1989 245 when I start it and goes off within one minute of driving. I might also had a failing ignition switch and wonder if they might be related. Thanks for any ideas.

If I recall correctly, that lamp is lit by a device that measures 5000 miles travelled since the last time it was re-set.

When it is triggered, it is supposed to be on for jusy a few minutes after start-up.

On all my 240's over the years I have disabled that system. On my 960's I have to (1) assure wife it is not an engine problem, and (2) prise out a little plug on the front of the instrument cluster, reach in a bit with something like a straigtened paper clip and push the button in there, replace plug and get the service done - oil & filter change at minimum.

I can't see any link to an ignition switch problem.

Good Luck,

Bob
