Lack of heat from heater

Hi, need a bit of help with cabin heating, I can put the controls to hot on both sides but I get a barely feelable warmth, engine temp never seems to get past a quarter on the gauge.
It's been bled but still no change, even putting a/c on in heating makes no difference, it's a 300tdi 1995, thanks

maybe your thermostat is stuck open, preventing the engine getting to temp

hi mine was exactly the same get new thermostat a good flush out with a hose up the pipes a good summer/winter coolent and am sure will be sorted mine has good heater now

Mine was the same due to heating matrix full of brown crap! Undo both top and bottom hoses to matrix and attach a hosepipe to one side leave to run for a few minutes and do on the other pipe aswell. My heating was cold for 2 month's prior to this lol
