Hi all just wanted to know if anyone knows about a disco 200tdi heaters I've got warm air not hot through the windscreen and footwell vents but all my vents along the dash are ice cold and also when the heaters are on there's like a rumbling noise coming from behind the dashcheers

No ideas about discos but maybe an air lock? Have you checked for leaks?

Yeah I've only fitted a water pump yesterday as it was leaking through the weep hole and I've bled the system today but still same problem

sounds like yer heater motor is on the way out, as for the heaters blowing warm how hot are the pipes in the engine bay going to the heater, cus if there only warm aswell you might have a dodgy thermostat (stuck open) or even a stuck heater flap, or even a blocked heater matrix (little radiator in heater housing), another thing to ponder is the drop in temperature at the moment could be a combination of two problems, cold air going through radiator and a stuck thermostat means the engine is not at working temp and over cooling hence warm heaters,also check coolant level as this being low could cause warm heaters also, if your heater motor is on its way out th only way to replace it is to strip all of the dashboard out and then you can get to the heater, takes me about a day to change a heater motor/matrix, but then i jugle spanners all day long, happy tinkering

Did it do it before the waterpump change? If not I would say an air lrock, jack the front up and try bleeding it again?

before you strip the dash out check your thermostat only a couple of quid and easy to do as its right at the front on top, take it out when engine cold and if its open theres your one of your problems.
