It's not an MB engine anyway. It's a Detroit Diesel (Michigan) engine, built prior to DDEC being bought out by FCA and/or MB.
Your timeline and assumption is way off.
Furthermore, if the compressor wheel is on the hot (exhaust side) any shrapnel would exit via the exhaust system / muffler. If the cold side (intake side) it would wind up in the ATA unit most likely. You always want any failure on the hot side.
You need to get your parameters straight. I worked on diesels for 35 years, the last 24 before I retired at a Freightliner dealership.
Irregardless, the turbo needs replaced because it has radial play which will at some point in the near future cause either of the compressor wheels to contact the housing and possibly explode.
One thing I always check on my 7.3 when I clean the K&N intake filter is shaft slop because accessing the cold side of the turbo is easy. Just takes a wiggle.
I've seen engines digest turbine wheels and it almost always results in an overhaul.
