I believe an oxygen sensor is a possibility, and unless the turbo had failed previously it is more likely to be an O2 sensor than a failed cat converter. I would find a Saab independent mechanic and they could say for sure. An exhaust leak somewhere might also cause this.
Take it with a grain of salt though, I don't have experience with this code yet. (knock on wood)
If you want to clear the code and see if it was a random thing (my rear O2 sensor triggered a CEL on the way home from passing my annual state inspection LOL and has not returned in the last month since).
Autozone should be able to clear the code for you, I have a scanguage2, which is a handy $150 toy.
