The P0116 is a coolant temperature sensor trouble code. The most likely cause is a bad sensor, also check for corrosion on the connector and for broken or frayed wires. It is located in the coolant housing on the rear of the engine, be careful not to break the plastic clips that hold the sensor and note there is an o-ring that goes in place before the sensor.
The MAF ( Mass Air flow) sensor is located right on the intake pipe. Can't miss it.

Coolant Temp sensor on the 1.8T engine is located on the driver side of the block. Following the radiator hose coming from the radiator, your see a plastic housing that splits the flow of water on the side of the block, on top of that black plastic piping is a sensor with a black flat plastic clip. Once you see it, you'll know, its the only sensor of its kind with that clip. Just make sure the car is off and cool.
