Hello mate.

The P0400 that turns on is because it detects an anomalous EGR flow (it reads it with the mass air flow sensor and compares it with the EGR activation percentage controlled by the control unit, in fact with the diagnostic you can see the desired values in command and those read). sometimes it is given even if you repeatedly press the brake 6-7 times quickly dissipating the depression of the circuit, for that I say that in 80% of cases it is a loss of depression from the sheath dresses. However, check that your intake manifold is not clogged too much and that the flaps move by moving the actuator by hand, and that you have no leaks from the intake / intercooler hoses.
