Well, last year I was able to make through a FRIGID winter somehow with a clogged heater-core. Dealer flushed it a few times and it got slightly better but not perfect...whatever that means. Got an "old school" fix-it tip from a mechanic that told me to flip the in/out hoses into the heater-core. Did so yesterday. Thankfully, temp guage is looking good so far and hoping heat will be returning shortly. Anyone tried this?

Heard that the heater-core is plastic and could run the risk of damaging with a graden hose. Fact or myth?

With your reversed hose hookup you're essentially back-flushing, except the crud stays in the system.
Now thinking about it what I'd do in your case is back-flush the core with a hose and drain as much coolant as possible from both the radiator and the block. This is to get rid of the goo that *was* plugging the core but now is circulating in your cooling system, thanks to the reversed hoses.
Just don't open the garden hose valve all the way if you're afraid to damage the core.

Cause that's what I'd do. Flush EVERYTHING to get rid of any goo and then refill. Wouldn't jump into replacing the heater core yet.
Am I wrong?

Find a radiator flush safe for plastic, pour iot in the radiator and let it sit, then backflush.
You still have Audi coolant, right? None of that aftermarket crap?
And are you sure it is the core and not a blend door?

Your headlight/CC stalk replacement was more up my alley than a core replacement!
I live in St. Louis, MO. I am using GEEN-YOU-WHINE G12 coolant. Dealer told me it was a clogged heater core, then called an hour later and offered to "get me out of the car".
