Failed Thermostat Housing/Coolant Loss Info Gathering

Update for me.... I was "slowly losing coolant", maybe top it off every month just to be safe. Mid intercooler install and took a look at things. Dealer is about 2 hours away and I'm still under warranty but I already have the coolant drained and such, so I imagine it would be pretty easy for me to do myself at this point.... I'll start looking around, but does anyone have a best price/part number handy?

Since you're under warranty why spend your money?

dealer 2 hours away, and time is money. I got a recall done recently though and their 'fix' made the issue worse, so maybe I ought to make a trip out anyways I guess.

Audi--passenger airbag light goes on and off. I think it's something to do with a connector on the bottom of the seat for the weight sensor. It kind of comes and goes but when it's there it's like constant alarms on the dash, super annoying.

No other dealership options closer to you? I’d think any VW/Audi dealer could do this repair for you since it’s the same parts.

Is this now been put out as a recall, you really don't expect problems like this especially given people are shelling out their hard earned dosh on VW

Is the mk 7.5 also affected?

Are you asking if this is a recall? The answer is no. They’re covering it under powertrain warranty but that’s it. Owners of other generations with similar issues have had to start class action lawsuits as a result of failures to get any satisfaction from VW outside of normal warranty period.

Remember to report issues to NTHSA.

Well, I’m visiting my in-laws who own a 2017 Golf Wolfsburg. I drove it an hour yesterday to visit some other family, got out and walked by the engine bay and smelled coolant.

Sure enough, this is what I saw when I opened the hood:

Well, it looks like I may need to get this looked at again sooner rather than later... As seen above, the thermostat and both water pumps were replaced on September 3, 2019.

Yeah, this is important, there is a certain amount of expansion/contraction of the fluid. When monitoring my level, I was always looking at cold car, generally first thing in the morning.
Just a heads up and I know technically it's not supposed to happen but I've seen the fluid level change just form air temperature alone. I keep an eye on mine and it will raise when I come back from Michigan (to VA)
