Report: Oxygen/Coolant Temperature Sensors May Fail
Volkswagen Jetta Problem
Exhaust & Emissions Affected: 2.0L 4 Cylinder
Average Mileage: 103,000 mi (78,000 mi - 130,000 mi)

CHECK ENGINE LIGHT- MULTIPLE TIMES WITH COOLANT SENSOR FAILURE
Visitor, 2004 Volkswagen Jetta, 130,000 mi
engine light came on and ended up being a coolant issue and was the themostate.
Temp Sensor failed, which made the engine light to go off. VW quoted me at around $600. Got it repaired at a private auto shop for less than $200 (if I remember correctly).
