Not sure if this is the same on the newer 9-3 models, but my OG9-3 recently had similar symptoms and it turned out to be a faulty circuit in the ABS unit. It can also occur if the speed sensor is not sending signals to the speedometer. On the OG9-3 this sensor is on the right rear wheel and can get corroded or gummed up with salt, road grime, etc. If you live in a snowy climate, maybe that is it? If so, cleaning the sensor can fix it. From there the signal goes through the ABS unit and then to the speedometer, so if the sensor is OK, then the ABS unit could be a culprit. Either way, codes should have been thrown that your Saab mechanic can read to get the details.
