Engine Fan always on, engine code p2181

I drive a 2014 Touareg V6 FSI and recently my engine fan has been on the entire time my Touareg is on. After a day or so a check engine light came on with engine code P2181.

I am guessing a relay or something electrical is out because I am having no issues with my actual engine temperature.

I have no idea where to start checking relays or where the fan relay module is.

Can someone please advise?

Thanks!

P2181=performance malfunction in cooling system. Check G62, engine coolant sensor and associated wiring for corrosion.
Go to Ross tech .com, wiki button at top of page, type in fault code in upper right box. This should point you in the right direction.

Not sure where you are but if you're in the US you have a 3/36 warranty. ?

2014 VW Touareg has a 10 year 100k mile powertrain warranty, don't waist your time and go to the dealership and have a Certified VW technician repair your issue.

In the photograph you are referring to it is located next to the water pump, however the G62 sensor is actually located on the coolant flange on the bulkhead side of the engine (opposite side water pump) and the photograph does not reflect this.
