Welcome to the Mercedes sprinter 2012 year 2.2 cdi ambulance. A problem arises with the boost pressure at high outdoor air temperatures, the turbo has been cleaned and the flow meter checked. Negative pressure in the engine, everything is ok, I know that with these engines, the Intercoolers...

Hello. The pressure is too high or low? Did you check the flow while driving? What are the indications?

Pressure during driving about 3-3.5 bar flow rate was checked by the Authorized Service. Error P2263 - turbocharger pressure control error (description of CDIF 3)

So it looks like overloading so cleaning the geometry will help solve this problem.

In this rub, new turbo from ASO

Do you have the option of making dynamic logs taking into account turbine pressure, revolutions and flow indications, preferably until the error is thrown and reported on the forum? because that would explain a lot.

I drove today from 5 am and an error occurred 3 times from an hour Ok 12 zero error nothing completely I have done the parameters high pressure turbo gives max 3.3 bar and low pressure turbo gives max 2.2 bar error lit at a speed of 100- 120 km / h I replaced the boost pressure sensor, temp sensor and further lime

Hello, I have the same problem as you. I have already done almost everything that is possible. Another thing we bet on a cracked suction manifold, as soon as I know something more I will let you know. What course does your Sprinter have? 316?

I wonder if the turbines complement each other well, maybe one is wrong.

Excavates the subject. Gentlemen, have you come to terms? More people have such problems in these sprinters: p

Welcome to the Mercedes sprinter 2012 year 2.2 cdi ambulance. A problem arises with the boost pressure at high outdoor air temperatures, the turbo has been cleaned and the flow meter checked. Negative pressure in the engine, everything is ok, I know that with these engines, the Intercoolers liked to swell, But unfortunately I can't see it so my question is where to look for the cause, whether it is the flaps in the collector or something else. I will add that when I deleted the error, it did not come back on when it is over 25 degrees outside and it gets sharply into the pipe and how cool it is

Topic summary

The discussion revolves around a 2012 Mercedes Sprinter 2.2 CDI ambulance experiencing a boost pressure error, particularly at high outdoor temperatures. The user has already cleaned the turbo and checked the flow meter, noting that the engine shows negative pressure. They suspect potential issues with the intercooler or intake manifold flaps. Responses suggest checking for overloading, the condition of the turbochargers, and the possibility of a cracked suction manifold. The user has replaced several sensors but continues to encounter errors, particularly at higher speeds. There is a consensus that dynamic logging of turbine pressure and other parameters could provide further insights into the issue.
