It is possible that the pressure in the expansion bottle is precisely because of the matix radiator, that could be clogged? or is it because of the cylinder head gasket or maybe even from the cylinder head?

Hi everyone. I have the same problem with the increased pressure in the expansion tank of the cooling system, and in addition to this, the clip holding the antifreeze hose to the heater matix is the 3rd time I have changed it. If I drive the car over 2500 rpm, I lose cooling liquid very quickly and if I drive faster, the egr hose enters this plastic part breaks. Has anyone encountered this phenomenon? The people from the Skoda service have so far changed 3 rows of hoses to the heater matix radiator, 2 times the cover from the expansion bottle, once they changed t he expansion bottle and the last time they changed also the exhaust gases radiator. I still have the same problem. It loses cooling liquid and creates pressure in the expansion bottle. And if I increase the speed, the egr hose that goes into that plastic clip that leads to the heater matrix breaks.
