Turbocharger emergency shutdown

Volvo Penta D3, 150HP

I was out on Sunday, cruising at about 1750 rpm, engine warmed, about 178 degrees. Increased power to 2000 rpm,where the turbo charger kicked in, slowly increasing power to 2400 rpm. About 10 seconds after, the engine completely shut down with an "emergency shutdown" notification on the helm display. I was able to restart the engine after swiping and reswiping the FOB. After restarting the engine, I simulated the same events and the same thing happened. The engine runs fine when the turbo is not engaged.

Anybody have solutions or have similar issues? The local shop wants $150 per hour, including travel time. Any help would be greatly appriciated.

I guess without the volvo tech and their propriety software we cant get the more detailed error code off the ECU?
is there a way to see the error codes on the volvo display after the fact - beyond emergency shutdown?

it could be the turbo but could as easily be fuel related as fuel rates go up at higher RPM.

a number of folks complaining on forums about the turbos on the D3. making sure you let them cool down from hot before turning off the engine and give them a blast at full RPM's regularily. (its not clear if the turbo is a variable vane or not from my reading)

It's not clear from you post what it is that indicates a turbo problem. Is there some information other than "emergency shutdown" displayed? Are manifold temperature/pressure(aka boost temp/pres) available on your display?

I am not familiar with the volvo, but I am sure there are similar. Can you check your panel to see hat your turbo pressure is increasing as you increase RPM? Is there a vacuum hose that goes to the waste gate and could it have disconnected? Can you check the vanes on the turbo and see that they are moving freely and none are missing?

At least those are a few things I would check.

I have A D3 and what Knotflying has stated is right on. You can see boost in the Volvo gauge. There is a vacuum diaphragm that adjust the vanes with a small rod the hose may have fallen off or split open. You can remove the air filter and do a visual inspection of the turbo vanes for build up. Good place to start.
