Default 4.2TDI radiator fan running constantly

I returned home after a week away and my car has developed an issue, basically the radiator fan is running constantly and continues to run for about 30 seconds after I stop the engine.

A quick scan revealed the following code:

Code:
                Address 01: Engine       Labels: Redir Fail!
Control Module Part Number: 4E1 910 409 A    HW: 4E1 907 409 
  Component and/or Version: 4.2L V8TDI  G000AGMª0070
           Software Coding: 0011773
            Work Shop Code: WSC 00503 503 81333
                      VCID: 22400330FD210608171
1 Fault Found:

006400 - Coolant Fan Control 2 
               P1900 - 001 - Open or Short to Ground
I am suspecting an electrical issue, bad contact or corrosion or possibly a faulty module, but before I start taking things apart I wondered if anyone had come across this before?
