blue smoke indicates oil is burning in the cylinders. This is either leaky valve seals, (little blue smoke when engine first starts, but stops smoking shortly after) or the worse problem, worn rings. What happens is when your rings are worn, they let oil get past the rings and into the combustion chamber, AND it also lets out your combustion pressure (your power source) into the crankcase, so you have considerable power loss. Only way to fix worn rings is to rebuild the engine, as just replacing the rings would require complete teardown of engine anyways, and who wants new rings in a worn out motor.

The fans are run by rad temperature, not engine temp on a VW.Somewhere on the rad you should see a wire harness plugged into it.That is a thermo-switch which turns the fans on and off based on coolant temp in the rad. My car is a lot older than yours but this switch is virtually hidden on the bottom driver's side of the rad. It has 3 wires going into it.There could also be another sensor attached to the engine block or head to monitor engine compartment temps after engine shut off. This will turn the fans on or off as well based on air temp in the engine compartment.
