Help needed!!!

[Glenn Luther]

Hi I'm new this this forum
And any help with my issues will be greatly received

I've bought a 2008 mercedes viano 2.2
And quickly found out it has a few issues but I'm stuck with one I've done a diagnostic and a fault has appeared


Atmospheric pressure between engine control module and charge pressure sensor is implausible

I'm shrugging to find the answer as apart from the sensor attached to the turbo ive changed all the others
Any help will be great thanks

I would venture a boost leak is the issue.

Read the actual values of the charge pressure sensor, vs the atmospheric pressure value, when the engine is not running.

They should be close to one another. If the atmospheric pressure value is wrong, then the ECU needs repairing.
