P2279 - Intake Air System Leak Detected
(11) - Present
When I follow the live data the pressure in the intake manifold is persistently elevated.For example, the default is 1.2 and the actual 1,6.The same happens at higher engine speeds and loads.The car normally goes until the engine warms up to operating temp.The pressure in the intake manifold is the same as a cold engine.At one point, just turn on the MIL lamp and starts horrible black smokes.
Error is only one
P2279 - Intake Air System Leak Detected

Turn the engine off and re-start the car normally goes and no black smoke.In the next accelerating all repeats.
In monitoring of the data, I noticed that this happens when the pressure in the intake manifold increases over 2kPa.
But it happened so fast that I do not notice of the current set and the real pressure in intake manifold at the moment of writing errors.I was changed swirl actuator that was faulty.I tried to close the EGR valve.I tried wastegate valve and actuator.Everything works but the error keeps repeating.

I saw on another thread that this can be solved by a software.

EGR Mate strip and clean out. Check the solenoid pin that operates the valve, if stiff strip it and clean and grease and rebuild it.

I tried it with a new EGR valve and again the same. Note that the pressure in the intake manifold is constantly higher than the nominal.At one point,in the higher engine loads and pressure in the intake manifold encounter this error.Map in engine ECU is original.
