Hi, my 2008 Golf gti has developed a problem regarding the small cooling fan. It doesn't seem to work. This is most noticiable when I have the heating/ac on and the bigger fan starts turning at high speeds for 10 seconds then stops, then starting 10 seconds later. With the heater/ac off neither fan comes on when it gets up to temperature. I don't have access to a diagnostics machine either.
Does anyone know what this problem could be?
Thanks
