Hi,

I had a leak at the rear heater that turned out to be the o-ring where the
control valve is bolted to the core flange. When I opened it up I found
pieces of white plastic caught in the control valve that look like twisted
flat noodle about 3/16" wide. Where could this have come from? Is it of any
concern? The pieces are very brittle so I don't think it would hurt the pump
if it got that far. This van has an ALH TDI diesel engine.

Thanks for any advice, a great list,

Ray
