Heater Matrix / Bulkhead Foam... October 26, 2021, 07:09:47 PM You'll maybe have read elsewhere I'm in the throws of changing out the heater matrix.Was going to just reverse the foam gasket affair that seals the 2 x pipes as they pass through the bulkhead but Heritage are doing them so cheaply got one of theirs.Unlike my original it has a third much smaller hole and it seems to line up with the 'V' channel on the matrix that's on both the original Valeo and the replacement Mahle.You could very easily run a pipe from the engine area into the cabin using it.Don't know enough about non-Gti's to recognise if it's there for something I don't have.
