Is redlining OUR C63's bad
Today I was on the freeway and decided to downshift in S mode into 3rd gear, well in the process of doing all the multitasking i forgot that i was not in shifting mode therefore redlining my car 
to the point where the car had to shift it self to 4th gear I want to know if i caused any harm to my engine or if redlining our AMGs is bad .... Is clicking noise normal for our cars too?

The car won't let you harm the engine. Running the car to the redline all the time will cause more wear and tear in the long run. But the car was built to be driven hard. As long as it's properly warmed up first, I wouldn't worry too much. As far as a clicking sound, can you elaborate? It sounds like you might be talking about lifter tick that goes away after the car is warmed up and oil pressure builds.

Just a small qualifier... bumping off the redline is not a problem for as long as the oil is up to operating teperature. You just don't want to do it when the oil is too thick to properly flow and lubricate (< 90 C / 200 F).

I tried to find a video of some work I did a few years ago on Chevrolet V8s hitting the limiter. If you watched the brutality happens with the timing belt (or in our case, chains); the crankshaft twist; the camshaft(s); the FEAD; & the unbalance introduced... you would avoid touching the limiter unless you really wanted to test the MB warranty.

That is all true and I completely agree. I think the OPs question was whether he had damaged anything by that single incident, to which the probable answer is no - that is, if you happen to hit the limiter on an upshft once in a blue moon (like every four months). Bouncing off the limiter all the time is certainly not healthy and is indeed going to shorten the engine life by a big margin.
I only get close when I hold down the left paddle to force a downshift and that never goes redline.
If I was to drag race I'd probably do it though
Not saying redline every gear out but these safety mechanisms are there regardless

The safety mechanisms are there so that your pistons don't become intimately acquainted with your valves or the conrods don't snap and punch holes through the side of your block. It certainly doesn't mean that just because the ECU won't let you destroy the engine by pressing the accelerator pedal too far, revving it near redline is without consequences when it comes to longevity and wear and tear. You are still beating the crap out of the motor.
