The car was showing different hidden errors like EGR , Intercooler Sensor , Charge Air Pressure so he deleted them from memory with another software. He then had to reset all the values of EGR , MAF , MAP etc. Car drives better now and the codes did not come back yet. Will have to drive for at least 100km or 200km so the car adapts agains the values. Fingers crossed
The 41AA code pointed to the Charge Pressure Sensor on the intake manifold - but lots of other issues can cause this to appear faulty. In your case, sounds like it might be the issue. time will tell.

It's not ISTA D that has the various fault memory locations - they are in the car itself. Different software applications (ISTA D, INPA, DIS, PASoft etc.) present the codes locations and values in slightly different ways and reading them etc. often requires some degree of interpretation.
