Run a VAG-COM on it. If you want to do some old school mechanics, run power directly to the fan and see if it spins, then you can rule out the fan.
It could be the relay... or perhaps the Coolant Temp Sensor, if it's buggered and not sensing the coolant is hot, it won't turn the fan on. The sensors are known to go in these, I just replaced mine for the opposite reason it would read high even from a cold start, and the fan would come on.
