flashing light on my temp. guage
 

Hey everyone. hope you can help, there is a red light on my temp guage flashing. the car is full of coolant and never overheats. it i let the car heat up and then turn the engine of and back on again the flashing light stops. the car feels like its driving perfect and i can't figure it out! any help would be apreciated!!
Cheers

it sound like you have a fault engine compartment fan. i would check that first.

thanx for the advise. another problem has just popped up so if you can offer any suggestions it would be great . my boxster wouldn't start today, the battery is fine just the starter wouldn't turn over when i turned the key.I thoght it might be a loose wire in the ignition so i took of the instrument cluster and checked. it was fine so i tried starting it again before i reconected the instrument cluster and it started.But when i reconnected the instruments it would not start.i narrowed the problem down to the connection (cluster of wires) that provides power to the dials, the one on the right side with the black cover(left hand drive).if this is connected i cannot start the car but if i disconnect it the car starts as normal and i can reconnect it when the engine is running and it causes no problems. Cheers
