Hi Guys
Looking at the owner manual and the fuse schedule.
Fuse 34 (bottom right hand) is a 30 amp fuse and is definitely listed as ' Electric windows front' That lines up with the graphic on the lower fascia panel also.
Fuse 30 is the diesel ECU fuse
2 members have now directed me to the bcu behind the glove box and the potential for a loose harness.
When replaced , Fuse 34 operated the windows fine for the first 10 minutes..
Just after 40 minutes of driving they wouldn't work and the fuse was blowing.
This suggests to me that the power supply is shorting out somewhere whilst driving and the cable is swinging around and earthing somewhere.
Let the search begin:)
