Not at all unusual for a 12 valve 103 motor to read 110C on start-up after its been driven and left to sit for a bit. Some call it heat expansion.

You now have all this heat build up and no longer have coolant circulation or air turbulance to cool things down.

After you restart the car, things should start to cool down considerably. Mine runs around 87C on the higway; occasionally around 90C if the A/C is on and it's REALLY hot outside.

In the past year I've replaced just about everything related to the cooling system and have found that a reduced coolant concentration did more for lowering operating temps than anything.
