Are those sophisticated electronics sending you any warning messages?
I hear Sprinters have a "Limp Home" mode and wonder if something kicked it into it.
A fuel filter's always a possibility. Ford - I could tell you what to buy and what tool you need. Sprinter - Nope.
I've seen this with gas engine vehicles and don't know why diesel couldn't do it also: Clogged Exhaust...
1. A pipe could have gotten crushed. Have you hit anything?
Even pipe can collapse. Some vehicles had double-walled exhaust piping. Outside looked good but inside had buckled. I really hope those days are over!
2. Catalytic Converter clogged by contamination or the monolithic media broke apart and chunks blocked the outlet.
3. Muffler with lots of internal rust. Rust breaks into flakes, clogs muffler internally.
4.0Screened tailpipe outlet plugged with rust from upstream in the exhaust system.
I went back and numbered these because I've personally dealt with all but Item 1. which I've only read about. In each case, the correction was field-expedient violence. Remove Converter, Beat till Pieces Fall Out. Chop hole in Back of Muffler with Claw Hammer. Punch Tailpipe Screen out with Tire Iron. Then replace parts as needed at home.
A lot of this was from when I used to transport rental trucks. We'd do what it took to get the truck where it could be fixed.
The symptoms were as you describe: More Throttle for Less Power. Kick an automatic into passing gear and the engine would rev but the truck would slow down.
Listen to the exhaust at the tailpipe. Should have a healthy "pulse." If you hear a "hiss" or "wheeze" then something could be blocked. Mechanics have tests to evaluate exhaust blockage.
