These cars are passing the dealer pressure test because they all have the same small leaks in the same place and the dealership is not leaving it hooked up to the pressure test long enough to see the slow pressure drop, if they left it longer it would lose pressure completely, do what I did and get under the car and get some pictures of the residue on the thermostat housing then present these pictures to the service manager.2016 GTI S 26K
I have added about 1/3 liter annually since buying it new.
Dealer pressure tested the cooling system in January (just before the warranty ended) and it was within spec so no parts replaced but the loss continues...
"Coolant loss is normal with these cars"
This is currently in testing. We hope to have it released by early 2020

One positive is that there may be an aluminum housing coming. This was the reply I got from USP when asking about a housing similar to what is available for the Mk6.
Please clarify (feel free to edit your post) that it was the thermostat housing and/or water pump that was repaired under the powertrain warranty.
Our dealer claimed that only the WP was covered at 59,xxx miles.
VW care is reviewing the invoice and is supposed to get back to me soon - fingers crossed. If they say "no", I plan on referencing this thread, reddit and previous ones where the majority of owners had it covered under powertrain, specifically for the thermostat housing + thermostat.
thanks!
Well, the phone call to VW "care" didn't work. I forwarded them the invoice via email after the initial phone call for further review.
After a few days, they called back and said - nope, not covered under powertrain warranty.
So, I have written a letter, included the Reddit thread with highlighted posts of each person that confirmed they were covered under powertrain warranty and sent it via certified mail, hard copy. Not email. Usually old-school can help, along with threats of social media (new school) might prove helpful... we shall see.
My water pump thermostat housing failed at 50,000 miles. Was covered under existing drivetrain warranty.
