Slow day getting home

MMMM makes me wonder if for the diesel in these rigs if Scan gauge will work. Having never driven one, do they have an OBII port? If so I would call Scan Gauge and see if they have a unit to read all the output from the motor and trans. At least one would have more info to go on.

Odd you didn't get an engine light with code for EGR failure.

Wow, surprised that lack of turbo boost affected power so drastically and that EGR valve was the culprit. Good to know.

So it's all OK now... Good! Glad you're back on the road in style.

turns out the problem was the EGR valve was sticking open and preventing the turbo from providing boost.

You are possibly experiencing limp mode. Could be the fuel filter, or could be a split air hose leaking turbo air out. If you are on the View/Navion forum, ask there, or on the Sprinter (NCV3) Forum.

We were lucky! When it happened to us, it turned out to be the gas cap. Replaced it (9.00), and the problem was solved.

Fuel filter would be our first thought, then fuel pump (had a failing one of those from being brand new!). Once our fuel pump was replaced we had no further problems after 18 months from brand new of limping everywhere overnight in the cool evenings, then resting for several hours somewhere during the day. Were told we had a dirty fuel filter on our first trip and they wanted us to pay for it until they finally acknowledged at manufacturer that we hadn't had it long enough to personally cause that and were using good quality fuel by the receipts, took almost 18 months to get resolved when we insisted they check the fuel pump = voila never a problem since and that was 13+ years ago.

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.

With a diesel engine, fuel pressure (fuel pump) is critical.
Let's hope for a clogged fuel filter.
