    Hard top radiator hose. Please help :/

    Hello, ive been searching for an answear,why my top radiator hose is getting really hard(not even able to squeeze). Ive changed thermostats, (bleed out air few times now) theyr working fine, did a CO test, it is positive., no oil in coolant, no smoke, everythings good except the swollen radiator hose. Now im starting to notice, that when i turn on the AC (20C) heat, it blows kinda cold air, sometimes hot. I am really pissed with the car, cause i cannot find a problem, so any help would mean alot, thank you! Car: bmw e90 2006 2.0D. They have also suggested that my EGR cooler is not working. What do you guys think?

    By "CO test", I gather you mean you ran a combustion gas leak test on the cooling system? If that's positive, you've diagnosed the problem and explained all the other symptoms, so I guess... what's the question?
    Are you gonna eat that?
