Audi A3 2017. 1.4cc automatic

I have done only 45k miles & when driving in auto transmission, only in 1st gear, it slips in that gear only, can do this when cold or hot, there are no warnings on the dashboard, anyone help on this subject

When was the gearbox oil last changed? 

Id recommend getting it in to be inspected

Sealed gearbox, do not require oil change
