Overheating while driving?

(2008 Volkswagen Jetta)
in Brandon, FL on July 01, 2014
I have a 08 Jetta never had an issue with it, and today while driving on the highway the thermostat light went on – beeping and blinking- however the actual gauge showed no movement and remained where it always is “normal temp”- any ideas what this could be? Im reaching out for advice before I take it anywhere and someone try to take advantage of a girl here--  any input will be greatly appreciated.

It could actually be overheating. I know it sounds wrong, but the placement of the sensor for the gauge in a jetta for some dumb reason often won't indicate an overheat if the coolant is low. It'll usually go up a little more than normal, but not always. The other sensor that screams at you and illuminates the dummy light will see the overheat. Check the coolant level, you might just be low. If the coolant looks nasty and oily you're probably looking at an oil cooler, common on these, so don't let the mechanic tell you the engine or head gasket is toast.
