Mercedes Vito dtc p2526

[pinheiro]

Hi friends

I have a Mercedes Vito, model 639, 2007, 150 Cv, 115 Cdi.
The vehicle, sometimes, lost power. By diagnostic it appears the following dtc trouble description:

P2526 Vacuum Resevoir Pressure Sensor Circuit Range/Performance

I have allready took off the turbo and it has been tested, including the Turbo Eletronic Actuator. It was ok, only needed to be clean.

But the problem remains.

What coulld it be?!

Regards

Hi
dont have understand why you have check the turbo if dtc are :
P2526 Vacuum Resevoir Pressure Sensor Circuit Range/Performance

check all that small hosses from vacuum ,can be from egr or in any other place something broken...also vacuum pump can be broken or maybe vacuum reservoir are broken/crashed
first of all check the vacuum pump with vacumm tester...

Hi friend

Thanks, but this car doesn't work with vacuum, the turbo and egr are eletronic.
Only the brake system uses vaccum.

Proper code definition for that vehicle:

P2526 Boost Pressure Servo Motor

Because you say it sometimes loses power, it's probably an intermittent internal fault in the servo motor, to replace it you have to get the whole turbo.

Tug on each wire at the connector to make sure there are no broken or corroded wires.
