More info would be useful

A few suggestions

Have you got fuel in the tank
Checked for a spark
Check fuse for fuel pump (common problem on Audi 80's)

Does the car start when jump starting it?

Most likely be a starter motor related problem?

Have you checked the current drain?

How long is "a period of time"? For elderly cars, immobiliser and clock can drain a battery over a couple of weeks, but not over a couple of days.
