Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.
What's the reason for changing it? Eratic temperature readings?

TO CHECK OR ADD TRANSMISSION FLUID TO JETTA IT HAS TO BE BROUGHT IN TO A VOLKSWAGON DEALEALER THERE IS NO DIP STICK EVERYTHING IS SEALED SO ONLY THE MECHANIC CAN CHECK IT.

check to see if your brake lights are working.usually the stop light switch fails and is the cause.but before buying a new one check the stop light fuse.its a common problem with a simple fix.hope this helps.

unless there is a ESP button (some cars have this feature, yours does not) no u can't turn it off. Have the system scanned by the dealer for trouble codes to help isolate the problem
