Question about 2002 Volkswagen Jetta TDI
Volkswagen 2002 Polo
I take it you have the radiator full and the drive belts properly tensioned.
Here is the ordered check list;
1) Get the error codes read-out. Many chain auto part stores will loan a meter to get this for free. Call. They may be mis-leading because of other problems, but may still be useful.
2) Check the fuses
3) If the radiator fan is not running while the car is hot you may need to check the thermal switch. This switch will turn on the radiator fan. If the connection to the switch was good, you may need to replace the switch. I believe the switch is in the lower section of the radiator with wires connected to it.
4) Check the thermostat and its housing for damage. Water has to flow through it.
I believe the temperature sensor that you see displayed on the dash is located on the engine near the heater hose. if everything else checks ok you may check this for false readings.
The problem should be corrected for the temperature sensor. The engine can be in hot/cold start mode and Lambda probe would get the wrong info.

this sounds like a thermostat fault, but also could be the sensor switch to the radiator but is more likely the thermostat, it should be located at the front top of engine, follow the top water hose to the engine and you will find the thermostat housing, also just a heads up, these had a problem when first made, according to the known fixes and problems with VW's the hoses corroded inside and started loosing water, this could be wise to get the system presure checked to...hope this helps
