No I did not added any refrigerant at all. Do you suggest to release some of the refrigerant to lower the pressure? If so to what value I should lower it? (now is 25 bar)

Paul, the cover is held in place by the following fasteners:
3 screws (2 located on the fabric portion of the cover on left and right side - where you have your knees when you drive, which the third one is new the hood release handle.
Then you have also a plastic nut located between the accelerator pedal and brake pedal, and a plastic philips screw which holds the lower vent grill attached to the console.
Finally there are also 3 snap-fit fasteners - you need to pull the cover towards the driver with some force. Do not use screw driver to pry it because you may damage the fabric. Good luck.
