No Heating E66

Hi Folks, looking for some advice. I finally got a E66 745Li but to say that i am getting to know it in a way that i was not planning would be an understatement!! But thats part of the fun..... When i got the car some 4 months ago the heater was working fine hot and cold, then the Drivers side stopped working i.e no heat then slowly the passenger side got weaker and weaker till no heat. I have confirmed the Aux pump is working and checked it for damage all ok removed the Control vales stripped and found one seal was broken, changed for a used one of ebay, pipes getting hot on the input and output side of the vales and have confirmed there is water flow through the heater Matrix

The car has had a new Water pump and thermostat fitted before i got it, i have stripped the Ebay Control valve and the seals are smaller but look serviceable. So am i missing something and should i be checking something else, Thanks

    Thanks, have been reading all of the chats in the forums and have come to that conclusion, looks like a trip to BMW spares and a hole in my wallet.
