The hell did the dealership do?

My dealer is excellent. YMMV.

I don't know about this specific car, but carbon build up on the intake valves on Audis and VWs is completely normal. Because of direct injection, no fuel runs over the intake valves to clean off the carbon build up. I'm a tech at an Audi dealership, and whenever we do a job that requires removing the intake manifold we almost always recommend a decarb. It can get pretty bad after maybe 100,000 km. I probably wouldn't have recommended it at 27,000 though.

Welcome to the gang -

Just for your information, as mentioned above, the FA20 engine is both direct and port injected, so the port injectors usually take care of most of any carbon that tries to buildup around the valves.

LOL
As Hum pointed out this should not be an issue with this engine.
As you pointed out even engines where it is an issue 27K miles is a ludicrous number to say it should be done. Hell, Granny's Impala that never see's over 30MPH could go longer than that.
As I pointed out if you have carboned up the intake on one of these engines you have bigger issues than build up to address.
As a few have pointed out this add on was a totally unnecessary up sell and the sort of stuff that gives all dealers a bad name whether they deserve it or not.

so was this issue resolved besides never going to a dealership for a tuneup

Apparently, it's related to the cleaner used on the MAF sensor. I'm waiting for it to clear itself, and it seems to have reduced slightly. When the engine warms up good, it still revs up when in gear and the clutch is pressed. If it doesn't stop by the weekend, I'll pull the battery cable and reset the ECU to see if that helps.

Good. I have 80k miles on my 2016. I recently had the plugs changed but only because I had to take my FRS in to get a new TOB. Yeah, i know the plugs and TOB are unrelated but I figured as long as the car was at the dealership, why not?

Only other maintenance has been oil and filter changes every 4k miles. Oh, and I changed the air filter once.
