No Heat..plz help!!

[SHAKSTER]

Its getting colder but i dont get any warm air . Ive changed the heater matrix but still no luck.

When i just start the engine, i get heat for the first say 5-8 mins but then it gets cold.

help!! plz!!

Does the car run ok? or does it overheat? Sounds like a blockage in one of the pipes going into the matrix maybe. Thats presuming there is coolant in the system

The car runs fine and their is coolant...

any more ideas?

Have you checked the by-pass valve between the 2 pipes that connect to the matrix, just a suggestion as this could be faulty. Run the engine for 10 minutes, then disconnect the inlet hose to the matrix , restart the engine and see if there is a good flow of coolant.

My car used to do the same as such but would probaly take a bit longer to blow cold.
after a while of head scratching a mechanic friend of mine noticed the rubber pipe from the metal pipe attached to engine going to the heater matrix (hope that made sense) was kinked,  it should have a bend anyway but not like this was, ?6 from vag and it seems to have been cured,
Definately worth a look at

I worked it out... it was the heater matrix by - pass valve. I get loads of heat now... theres a kink in the rubber pipe which i will sort out.. thanks mate
