It all depends on the price. I got my 2013 with the same S-line Titanium Sport package as you with 46k miles for $13k back in December of 2019. keep in mind that at that mileage and time period, it still had the extended emissions warranty.
Obviously used car prices are still pretty weird and I'm out of the loop as far as what prices are now, but I probably wouldn't spend more than $6-7k on that, especially given that it's out of warranty (unless you plan on immediately deleting it/tuning it). At that price, provided the rest of the mechanicals are in good order and the body is free of rust, you'll be able to assume a bit of risk on the DSG and if it dies, you'll have the cash to drop in a low mileage used one.
