    I have an issue with my 2013 Mk7 GTD 50k miles. It seems I can get little to no hot air through the vents. After reading various threads it seems the silicon bag in the header tank may be the culprit. The bag is not in the header tank and the coolant is the correct colour, could it be something else...sensor? Or will the matrix defiantly be blocked?

    many thanks

    Can you get to the heater hoses to see if both are hot?

    I know on mk7s its a big issue that the matrix blocks up.

    Yes they both felt hot, there doesn’t seem to be an answer as some people say they change the matrix but it just comes back?
