A3 8V 2018, DSG, leak on engine to gearbox/driveshaft

Hello All,

During routine maintenance of oil change, I've noticed some sort of leak/oils what seems to be a connection between engine and gearbox/driveshaft assembly? Pardon my inexperience, I have no knowledge on FWD Audis cars.

We are not aware how long it's been there or how fast it's progressing. 

Car is A3 8V from 2018, 1.5 TSI motor with, presuming, DSG DQ200 gearbox. Mileage is around 145k km 

I've cleaned that up and after driving the car for 50 km and then letting it rest overnight, here's how it looks on very next day:

Local workshop mechanic have a quick glance and he said, the only way he's going to fix it, is by having total gearbox service, which would cost around 1000 GBP including labor, thus we backed off for a moment. 

Anyone knows what it can be? As far as I'm aware, the 1.5 TSI and DQ200 is a common combination among VAG cars.

Thanks in advance.
