Good morning SpookyZalost
Of course, it is possible to control permanent positive (30) to ignition positive (15) via a normal working relay, I don't know exactly the Jetta, but if there is now a permanent positive on the engine, it is easy, it is controlled via minus from Thermal switch on the cooler. I have a Golf 5 built in 2008 and the fan power supply is controlled directly by a control unit via a relay. There is only electricity plus at the fan motor when the control unit is working everything by Can-bus
My tip, read the errors from the memory, I have the workshop programs such as VCDS or VCP for VW and Audi Porsche. A cheap tool like this one, for example, is sufficient:

Important, simply delete non-open or closed errors, read them out first, write them down, then post them here and only then delete them
