SOURCE: VW Polo Classic 1.6 Radiator fan not going on

Try moving the fan blades by hand to see if the fan spins freely to see if the problem is frozen bearings in the fan motor. Replace the fan motor if it doesn't turn. If it spins freely disconnect the wires and hook the fan directly to the battery using a jumper. If it runs the problem is most likely the thermostatic switch. If it doesn't the fan motor is bad.

try disconecting the coolant temp sensor and then try, it may be faulty, also check the hall sender unit in the distributor, if it has one, the centre pin should be the signal wire if no pulse is present the sensor is faulty

SOURCE: VW Polo Classic 1997 IDLE Problems

Hello, VW polos 1.0, 1.4. 1.6, suffer from carbon bulid up in the throttle bodys causing bad idling, esp the Bosch Mono-Motronic (Throttle Body Injection systems), a good clean with carb cleaner should repair the problem, also engine temp sensor replacement and idle speed control valve replacement can help idle problems.

Has the car been serviced recently?
If not I would suggest getting it done.Not sure if you have diesel or petrol, but oil can thicken causing more load on the motor and airfilters get blocked and can cause a rich fuel mixture.

If petrol you can take out the plugs to check if they are a light brown colour, if very dark or black you need to check and adjust carb/injection settings/filter.Need to know what engine it is really.
