The engine system service required message shows and the amber triangle and engine symbols are on
Poss coolant temp sensor or temp sender. PS, are u sure that switch is wired properly may also be a bad switch.
SOURCE: electric fans run all the time
The radiator and A/C condenser fans are triggered by high coolant temperature or when the A/C is turned on. Check to see if you have a relay sticking closed. The (ECT) engine coolant temp. sensor could also be defective telling the computer that he engine is too hot all the time. If you can locate the relay it's much like the others and you can swap it with a good one for a simple function check.
SOURCE: Why does the fan keep running on 2005 jetta after turning off
You are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off. Quite normal operation.

if computers arent picking anything up its not an electrical fault, sounds like your surging because of bad fuel or blocked injectors, run some fuel cleaner through the car and see if that makes a difference. fuel filters may need to be changed but try the cleaner first.

The exact same set of codes have just come up on my car, the same car and year. Did you solve it? I am thinking cleaning the throttle body first, any help appreciated....
