A3 1.6TDI Cabrolet 2014.
Battery has been replaced but when left for 4-5 days it goes flat and will not start the car.
Further investigation has shown that with the doors locked and everything off there is about 700mA of current being drawn.
By pulling fuses I have isolated it too F45 which is 5A. Current drops too 20mA.

ERWIN shows this as supplying the electrically adjustable seats which this car does not have. Also shows the fuse as 15A.

Anyone any ideas on what the fuse does?

Note fuse has been pulled and car drives and all functions appear to be there!

Many thanks
