Saab 9-3 Sedan/Combi/TurboX/AWD(2003+)/Conv(2004+)
Went out today, everything fine, car hasn't driven this well since I bought it.
When I got home i left it idling in the yard for about 10 minutes while I potted around. Then the car started making a funny noise, a bit like something clicking on off very fast, but the car was still idling fine...
