Jim,
I've been considering the purchase of a new Mercedes-Benz 2025 Sprinter van with the 4-cyl. twin turbodiesel engine. It's performance specs are great, I haven't read or heard anything yet about its holding up though.

Mercedes-Benz also increased the number of gears in the AT, (automatic transmission)

The engine had been the 3.0 liter V6 turbodiesel, for years and years.

When I saw the thread title, 4-cylinder.....that's why I posted my interest.

I drive a 24 Mercedes 2500 4 cylinder everyday. Good truck. Engine is resilient. User interface is dumbed down (no dipsticks). One odd thing is the owners manual states it’s normal to burn a quart of oil every 600 miles. I have been staying on top of the level via the dash display but it’s a weird combo for an admitted burner not to have a dip stick.

It also empties the DEF tank every three tanks of fuel. My 2016 would go through 5 tanks of fuel per DEF refill.

Another quirk is the touchpad on the steering wheel. It’s real easy to brush it and change the display. I have tape over mine.

The engine seems well designed as far as endurance though.

Talked to acquaintance that has a GLx with the turbo four. The engine had a catastrophic failure at 65k miles. Reported on the paperwork that valve broke then connecting rod came through side of block. Jackson Automotive, Macon, Ga replaced the engine at no cost to the owner.
