Sprinter Diesel Power Loss Resolved

My 2015 Mercedes Sprinter diesel is having power loss issues, a check engine light, smoking during acceleration, rough engine performance, increased fuel consumption, and jerking with a hissing noise. Could this be the EGR valve?

That sounds bad. Hissing and smoke are never good signs. EGR valve problems are common on diesel engines. Does it have a rough idle? It could be a vacuum leak, but the EGR is a prime suspect. Are there any specific error codes?

Yes, the idle is sometimes rough. I haven't checked the codes yet. If it's the EGR valve, does it need professional attention, or could I do it myself?

Given the symptoms, especially the hissing and rough idle, and potential catalytic converter issues, I'd recommend a workshop visit. A messed up EGR can cause serious problems. It could be other things, so better safe than sorry.

I took it to a mechanic, and it was the EGR valve. The replacement cost 355€. The hissing is gone, the engine runs smoothly, and the power is back. Thanks for the help!
