My 07 Sprinter has a chronic problem with the turbo going

Customer Question

My 07 Sprinter has a chronic problem with the turbo going into safe mode.

Hello. My name is ***** ***** I will be helping you today.

What do you mean by safe mode?

Have you checked it for codes? If not that is the best starting point here.

Customer: replied 11 months ago.
Turbo shuts down and usually doesn't trigger the engine light. If I stop, turn off the engine and then re-start, the turbo resets itself.
Expert:  Wayne Crawford replied 11 months ago.

Have you checked the codes? Its most likely a leak in the turbo plumbing but I would check codes before wasting time checking all the plumbing.

Customer: replied 11 months ago.
Within the last 6 weeks we have replaced the turbo, swirl actuator, egr valve, rear wheel tone ring, plus other things. Code comes up just saying lack of boost.
Expert:  Wayne Crawford replied 11 months ago.

It doesnt give you a number? What kind of scan tool are you using?

Customer: replied 11 months ago.
I don't know the number. My mechanic (s) see it.
Expert:  Wayne Crawford replied 11 months ago.

Have you tested the turbo hoses for a leak?

Expert:  Wayne Crawford replied 11 months ago.

Did the old turbo and new turbo have the same classification/correction codes stamped on them?

Customer: replied 11 months ago.
Tomorrow a mechanic is going to use a smoke machine to kook for that, but doesn't really think that is the problem since the shutdown is so intermittent. A year ago my engine light came on and it was for the diesel particulate filter. Nobody new what to do about it. It stayed on for a week then went away. Could that be a source of the problem?
Customer: replied 11 months ago.
Turbos were the same.
Customer: replied 11 months ago.
I can find out the code number tomorrow.
Expert:  Wayne Crawford replied 11 months ago.

I dont think that would have anything to do with it. Without knowing the EXACT description of the code or code number I wont guarantee it though.

So you personally verified those numbers on the turbo were the same?

Customer: replied 11 months ago.
Expert:  Wayne Crawford replied 11 months ago.

Then I think its safe to say you have a leak in the turbo plumbing.

Customer: replied 11 months ago.
The code comes up PO299
There are no leaks in the turbo system.
Expert:  Wayne Crawford replied 11 months ago.

How did you check for leaks? I still suspect a leak for what its worth.

That code is not valid on the sprinter.. it is sometimes flagged by a cheap code reader but it shouldnt be. I would get a decent scan tool and see what the real code is.

Customer: replied 11 months ago.
That code comes up for the Sprinter even on YouTube. It shows all the different places that can cause the problem. The leak test was done with a high- pressure smoke machine. Showed no leaks. Right now my guess is the mass air-flow sensor.
Expert:  Wayne Crawford replied 11 months ago.

Perhaps. That doesnt make it any more valid of a code.

Regardless that code does indicate a leak. If its not the hoses I would suspect the EGR cooler.

The only common denominator I can find is HEAT. We drove on the interstate half the day yesterday with no problems, even down-shifting to get over the hills. The problem started as soon as the temp hit 81 and we got in stop & go traffic.. the turbo shut down 4 or 5 times before we got to our destination.
Expert:  Wayne Crawford replied 11 months ago.

Is it ambient temp or engine temp that changes it?
