My 2019 GLI Autobahn started leaking coolant around 22k miles . Took it in to the dealer. Waited 2 weeks for the part. They replaced the water pump under warranty. Im at 25k miles now and im leaking again. Its still a really slow leak but I smell coolant when im parked or get out of my car. when I top it off, after about a week it goes to the bottom of the fill line. Going to call them tomorrow and see what they say. Tired of smelling hot coolant.
There was a class action lawsuit on this that recently settled. I'd look into that in the case that you get an flack.
You may have a leak somewhere else, or the thermostat housing wasn't seated properly when the assembly was put back together. That's normally where the leak comes from.
I agree with
@anotero. You are losing a lot of coolant if your tank needs a weekly refill. I'd look at all of the connecting hoses, turbo, etc. A lot of times, the dealership just assumes it's the water pump because of it being the common failure point. Also, get a second opinion at a different VW dealership if you have any issues.
