EFK question.
I bought a neuspeed 190 fan switch so that the fan comes on sooner - more like when the OEM fan comes on fully.
You can also get a universal fan switch that can be adjusted to whatever temp that you want...
I did a search on this back then and someone posted that there is a rabbit or golf thermosdat that is a better temp - but I could not find the part number or exact application. Hmmm B6 1.8Ts have an electric primary fan - maybe see if the switch is the same design, that one may work, or just get an adjustable one - WYSIWYG has had good luck w/ his...
