nedssx 0 Posted March 11, 2010 Going to be replacing the matrix in my c in the next couple of weeks. The previous owner has bypassed the supply from the engine what pipes do i need to reconnect with the new matrix? Any help please :shrug: Quote Share this post Link to post Share on other sites
davidwort 0 Posted March 11, 2010 heater matrix supply and return hoses! the recall on the 16v added the two bypass valves, a new hose needs to be cut if you want to retain these, but there's no need if you buy a new genuine VW matrix as the are redesigned. It's possible one of the 16v matrix hoses is no longer available though IIRC, try GSF etc, ot amke up the right hoses from an elbow reducer and straight lengths of silicon hose from samco or SFS or similar.
