The fans usually have two modes, high speed and low speed. Sounds like your low speed mode is not working. That could be because the fan is dying, which is not surprising considering it's now 12 years old. The other potential cause is the fan controller.
VW/Audi products start to fall apart around 10 years. My VW Golf which lasted 14 years started having issues around 10 years old. I had one of my fans replaced around 10 years, and the other followed soon after. It starts to really get expensive if you have someone else do the work. I was spending basically every weekend working on my Golf toward the end. Fan, fan controller, A/C compressor, dryer, EGR, fuel door release, ignition switch, coolant flange, thermostat, idler pulley, window switch, etc., etc.... and that was on the venerable ALH engine which can easily last 300K miles or more.
