Angry Coolant fans run all the time, VW

Coolant fans run all the time, VW

VW Golf TDI 07 plate,

This is in fact common to see, fans run all the time with key on, on running a scan test you may find no codes, but first check 01 engine and elecs:1 and the air con system, test the live data for the coolant temp is right for the temp of the engine.

Check the temp sensor in the bottom hose, grey plug, you can get at it by removing the air box.

If all is ok the fault may well be the fan it's self, the big one to the near/side.

This fan is more than just a fan, it has a module built in and it can fail, making the two fans run all the time

It's a new fan, no other fix
