If its any help I measured my old S8 (FL) current draw with everything shut off, key out, at 0.24A (in the battery compartment, multimeter in series with battery)
Get yourself one of those clamp amp meters so you dont have to keep disconnecting the battery to put a standard multi meter in series. I need to get one too.

(make sure sensitivity is enough for low currents)
If you already measured it to be 0.35A, that shouldn't be high enough to kill a 95Ah fully charged battery in a week.
95x0.8/0.35 = 217hours, or 9 days to go down to 20% capacity.
Although its 0.35A is a bit high, have you run a VCDS auto-scan with everything switched on including the radio? Radio will sometimes only show speaker-to-ground errors if its switched on whilst you scan it.
Also, some cars apparently go into sleep mode 15~20 minutes after the key is out, so may be worthwhile measuring current draw again to see if it reduces.
