Took it straight to my local SAAB Specialist, and they couldn't find a problem. Checked engine mounts, exhaust mounts and bolts, belt pulleys etc etc. It went away after a week, never explained it, and nothing has gone pop since it went away. Not a great help I know, but I would suggest you let her "bed in" or a few hundred miles first. Al
