Default Coolant Fan Not working

Hello all,

On a recent trip to the city of Melbourne I had the coolant level alarms come on in the dash. I check levels frequently and have not had this happen previously. The stop start of the city caused the car to overheat as the fan was not engaging. Upon returning home (temp is fine on the highway as airflow is good) I ran a VCDS scan that returned the following:

Address 01: Engine Labels: 077-910-560-BFM.clb
Part No SW: 4E0 910 560 S HW: 4E0 907 560
Component: 4.2L V8/5V G 0030
Revision: 00000000 Serial number: AUX3Z0E3363303
Coding: 0005773
Shop #: WSC 10080 959 93516
VCID: 313FEB0E8D28031F213-8064

3 Faults Found:
17544 - Fuel Trim: Bank 1 (Add)
P1136 - 001 - System too Lean - MIL ON
17546 - Fuel Trim: Bank 2 (Add)
P1138 - 001 - System too Lean - MIL ON
18080 - Coolant Fan Control 1
P1672 - 004 - Open or Short to Ground

Readiness: 0000 1001

I am aware of the fuel trim alarms but the coolant fan is a new one.
Ross Tech does not offer a solution for the P1672-004 code but I gather it could either be:-
Fuse - checked and OK
Relay - Unaware of location, Can anyone advise Pls
Fan Control Module - I believe it is integrated into the fan
Loose Connection - Could very well be as I have just had the timing belts replaced.

Can any offer any advice on any of the above points or if they have experienced the same problem. It would make life a bit easier rather than pulling the front of the car...Thanks in Advance.

Regards

Chris
