Ray Komar, the P0116 code on the VW means that there are issues with the " Engine coolant temp circ. range/performance Coolant" It is most likely that the Temperature Sensor (CTS) is failing and/or a new water pump is needed. Hope this helps, good luck.

Ray Komar, the P0116 code on the VW means that there are issues with the " Engine coolant temp circ. range/performance Coolant"
+
Possible causes
+
- Low engine coolant level
+
- Faulty Engine Coolant Temperature (ECT) sensor
+
- Faulty engine coolant thermostat
+
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
+
- Engine Coolant Temperature (ECT) sensor circuit poor electrical connection
+
Coolant temperature signal sent to the engine Control Module (ECM) is not within specified range.
+
Symptoms
+
- Engine Light ON (or Service Engine Soon Warning Light)
+
P0116 Volkswagen Description
+
The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. from [http://www.carobdcode.com/p0116-volkswagen-engine-coolant-temperature-sensor-1-circuit-rangeperformance-problem#.UnrWOydjGSo|here]
