Just had a look around the forum on the topic of replacing the matrix, I was doing some work on my cabriolet today and noticed a bit of what I think is coolant in the plastic vent pipe near the handbrake, I have a good bit of the dash out anyway so I think I'll bite the bullet and do it, any good sources for a new one? I presume water from outside can't find it's way down that far! although given the last few months here nothing would surprise me. I rather do it now than be left on the side of the road somewhere in Europe!
