1,5 TFSI 2023 A3 Antifreeze leak

[Grga 8Y]

The car has 21.000 km, a month ago I received the warning to check the coolant, and coolant was indeed low, I had to fill
a little bit more than 0,5l to reach MAX level.
I thought it was very hot summer, and after 30 days coolant is near the MIN line, it looks like it it leaking somewhere, from
outside I don't see any signs.

Anybody with similar situation?

I had exactly the same thing at virtually the same mileage.

Let's hope it's a chronic airlock

Yes, mines 7,000 miles on, and no further loss

Can be many things. In my case: pressure test hasnt shown any leak. Was looking below the car before each run, finaly single drops appeared under the water pomp.
Presure test was usless because it leaked only with engine started.
Careful inspection with white towel can help.

Hi, is this an 8Y problem you are referring to, as I thought the water pump leak was resolved during the 8V lifetime, so would be surprised to hear about it returning on the 8Y.
