If you slightly bend a valve it will eventually break off at the stem, destroy the associated piston and rod, destroy the block, destroy the head, then take out the turbo as pieces exit the motor.

Not always. Had a friend that ran for like 3 months on a bent valve before we fixed it.
If it was bent though, you'd know by the exhaust sound usually immediately

You can always check VCDS for over-rev flag, that may be of some indication if you're liable to have damage.

Yup....mine ran fine for like 5 minutes after it happened, then went into "sounded like a diesel" mode, and then it finally just died on me while trying to limp it back home
I have an appointment with my local APR VW/Audi private mechanic shop on Thursday. Asked for compression test and pull any codes via vagcom. 3 times, It will be peace of mind knowing everything is okay and I'm gonna drive like grandma from now on 
I will update on the outcome

Newbie to this forum, but I've been trolling for a little while.
It is what's known as a "mechanical over-rev" and it can cause damage if the engine is an interference engine (pistons and valves collide). If the EA888 is a non-interference engine, the computer may still show the accidental over-rev and register it.

I hope my reaction time was quick enough! - all 3 times. Thanks to the fellas on this forum, I'm practicing the better way to shift. I've really lost my touch since I've got a company truck - the gti is a weekend car.
Dropped it off today, the shop looked at me like I was crazy wanting a compression test done at 12k. Peace of mind is all I want, especially with winter coming. Will update with results.
It almost like getting struck by lightning 3 times and living to tell about it .
All is swell with the gti, compression was good on every cylinder. They did find over rev codes, a cam code and a few other mis-communication codes - they weren't sure if those where due to the tune.
They cleared all codes and test drove, nothing popped up again. I'm just happy everything is okay mechanically. Phew !!

See, like I said you were more than likely fine, but I guess better to have it looked at and get the reassurance that it's all good.
