Cooling fans on constantly

Post by Chrisg1980 » Sun Jan 04, 2015 10:26 am

Now then fellas, just bought an 07 TDi and the radiator fans seem to be running constantly. Anyone got any ideas as to what it could be or had this fault themselves?

Cheers, Chris

I have had this problem before...
Has the outside temp.display gone too?
The wire to the sensor in the front bumper breaks...the engine then has no outside air temp,so that makes it activate the fans.
Common fault.

Hello mate, thanks for the reply. The temp gauge is working fine. Hmmmmmm, the plot thickens

On a lot of vag stuff, if it has the control module bolted to the rad, these can fail. First thing is get it code read with live data to see what it thinks is going on. Do you know anyone with VCDS?

I am just looking at getting a maxi, so can't tell you any more than that unfortunately as not had a lot to do with them, yet!! :-)
