Having spent a ridiculous 16 hours sorting Heater Matrix - including cleaning out air intakes of water, glycol and K-Seal - found that I still need to replace the Thermal Resistor to get fully functioning fan speeds.

I now need to identify a source for the persihed foam gaskets that covered the doors to the Heater Matrix Box to ensure that the air flow is suitably directed.

I have identified that the Foam Gaskets for the "doors" in the Heater Matrix Box have perished and I need to source some new material.

Does anyone have half a clue what and where I can source these little gems of technology ?

Are they something only VW can supply or should I look for them through a particular agency like RAM Gaskets http://www.ramgaskets.com/gaskets/foam-gaskets/ ?

Are the foam gaskets made from Silicone, Nitrile, Neoprene, EPDM, Polyethylene, Viton ?

Eager to find out so that I can fit - less than 16 hours this time - before the end of the short UK summer in time to heat my journeys.

Very much looking forward to a little less time with my head pushing the clutch pedal to it's fullest extend while I try to manipulate the metal spring clip onto the Heater Matrix Box on the driver side of the box with a screwdriver or something !!

Many thanks for kind replies.
