This seems to happen only in very warm weather. After driving for about half an hour the car seems to go sluggish and does not change up into the higher gears - revs stay high and overtaking on the motorway is impossible. Changing into manual mode seems to help. The yellow engine block warning light comes on at this time. This first happened 2 or 3 years ago during a rare warm spell, but my local (non-saab) garage couldn't identify a problem. No probs until now, when we have hot weather. Any ideas please?
