Hi All, I currently have a VS berlina and recently replaced the head gasket. Since then my heater has been very temperamental. Most of the time it only brows clod air but there are short times when it will blow hot air. I have already read the forums and I have bled the cooling system over last few days and does not seem to be anymore air in there. I have also checked the heater tap and it seems to be working fine with both in and out hoses feel hot. Im sorta stuck now as to what the problem might be. Any suggestions would be greatly appreciated. Thanks
