alex darcy 0 Posted October 1, 2003 my heater is not getting hot, it gets warm for about a minute then is stone cold. i changed the matrix which i assumed was blocked, but it wasn't!!! i'm wondering if that alloy 'T' piece is for on the pipe entering the matrix, looks like a non-return or something? its in the engine bay by the way, any ideas as winter is coming, the water is getting hot by the way cheers Quote Share this post Link to post Share on other sites

Fine wine, Belgian chocs. 1 Posted October 1, 2003 Had this problem with my old Mk2 GTI and I think you're right about the 'T-piece thing'. It's a pressure relief fitted on a recall to stop the possibility of the heater matrix exploding. Try removing it temporarily and linking the pipes up with some tubing and jubilee clips. If the problems solved then either get a new one from VW (about £30 if I remember rightly) or leave it out and don't worry about it. I left mine out of my Golf and never had any probs but I suppose it must be there for a reason. :D Quote Share this post Link to post Share on other sites
