I've got a 2010 Tiguan Sport &a Style 2.0 TSI 4Motion and the large fan has been coming on fairly loud (fast) in light traffic. Seems to come on for 30 sec, then off for say 10 or 15 then back on ...... once the car is shut off it runs for a little while as it always has then turns off which seems like normal cooldown.

I'd noticed the smaller fan come on with the AC when starting the car which also seemed normal but it didn't seem to come on when the cars hot to help the big fan. I took it to a local VW service agent, they did a code check which indicated "coolant fan control module No.2 faulty.

They replaced the small fan and cleared the code and the rescan was clear, but I still feel the larger fan is working harder than I remember.

Everything I've read indicates the fan controls are in the large fan which wasn't swapped out, am I worried over nothing or did they swap out the wrong fan?

Car temps (water and oil) and all fluids are good.

Any opinions would be most appreciated.
