When should I change the gearbox oil on my Audi A1 S tronic?

I have owned an Audi A1 1.4 TFSI 185PS for 3.5 years and overall am very happy with it. However I am confused regarding the maintenance and servicing for the S tronic automatic gearbox. My servicing booklet mentions oil and filter changes from A3 right through the range up to A7, but no mention of the A1. My dealer says the A1 S tronic doesn't need any attention as far as oil change is concerned, but this just doesn't seem to make any sense to me. Or am I just being over cautious?
This is the dry clutch seven-speed s-tronic that was designed to be maintenance-free on synthetic oil. But the synthetic oil can become conductive if it gets too hot, so there was a worldwide recall to change it to mineral oil, which has probably been done to your car. That won't last much more than three years.
