Yet another surprise today with my troublesome Boxster.....
Went for a drive with the wife, so gentle, about 30 miles to a couple of local sights, car started smoke-free (3 times in a row...wow!) and ran a dream, everything as it should be.
Parked up and went for a 2 hour walk and lunch at a National Trust (I'm retired!).
Got back to the car, started it, no smoke, gosh.
Then 'ding' the Check Coolant message came on and the temp gauge read 120+ C.
So the car had stood still, engine off for two hours and gone from 80 to 120+C.
Drove the thing out of the park for 1/2 mile and suddenly the message went and the gauge sank to 80 in 3 seconds or quicker.
1/2 mile or so later, ding, message and 120C in 3 seconds, a further distance and back to 80 where it stayed all the way home running sweet as a bird.
Must be a temp sensor.
Anyone with a similar experience and a solution please?
