i had the back caliper over extend on me as well. Thankfully there is an easy solution.
1) use a c clamp carefully push to piston in till it rests against the extended internal parking brake screw. Push on the center.
2) Now the dash control will let you go to the retracted service position.
3). Use the c clamp again to push the piston all the way in.
4) replace pads and put back together. Use dash menu to put parking drake in operating position. All good now.
Dealer as usual is full of it. Easy fix!!

Man i made an account just to thank you for this!
I was in all sorts of anger after being stupid and pressing okay on the pad change function before i was finished resulting in the over extended pistons.
after a few tantrums I gave up went inside and happened too read this, I went back out put a C clamp against the piston a thick rag too cover the casing behind, after that i applied just enough pressure to trick the dashboard into thinking I had the pads installed this then allowed me to activate the pad change sequence again and push the piston in the rest of the way by hand with ease
THANK YOU MAN!!!!!!!!!

Hello there! I am in the exact same predicament. I have a 2017 C63 s. I tried changing the rear brake pads. The initial activation of the 'brake fitment mode' worked. But when I placed the new brake pads in, the caliper obviously needed more space. what i should have done at this point is manually wind the piston in. But stupid me though that maybe the fitment mode had reset so I attempted to enter the fitment mode again by first coming out of the fitment mode (this made the e-brake engage and the piston came way out.

The question I have for you sir is that c-clamp did you use to push the piston is? As on the AMG TRW brake systems, the calipers have a name plate on top.
Any help is appreciated! thank you.
