[Vwdiesel] the core of the Problem?

[Roger Brown]

I'm not sure if the A1s have that setup in the heater box.  I've never run into that 
problem or needed to replace that foam on any of the A1s I have owned and the last two 
have had 250K+ miles on them.  I have heard that is a common issue on the A2s, though.
