Sitting at the service station in my SL500 after filling the tank, I did the usual reset of the trip meter.

Then I thought I should change the clock that was lagging by 20 minutes. So while the engine was running I pulled the clock knob out and turned it to start the hands moving.

As I did this, there was a flash from the warning lights at the bottom of the dashboard... about half the lights on the lefthand side blipped on and off quickly, and all the needles (fuel, amps, revs etc dropped to zero then came back up again.

Happened twice each time I changed the clock hands. What's going on here?

Nothing to worry about at all, in my opinion, Ken. The affected gauges and warning lights are controlled by a microprocessor which simply reset due to a voltage anomaly caused by your adjustment of the clock. Same thing happens on many cars when the turn signals are used. I'll guess your engine was not running when you saw this and that it does not happen when it is.

Thanks Bob, that's a relief. My 'good service' MB shop has sold out and changed ownership, and to get a warrant of fitness which is now due I have to go to the franchised dealer. I was going to take up this fault with them, but will leave it alone and save some serious money :)

(Unless it is as serious as Carlo$ suggests. I may just leave it until something happens - but I hate the thought that there's a fault lurking, waiting to get me in some unsuspecting moment on a highway far away).
