1.8T sludge poll

[David]

I'm calling BS on some of what he said. It's the part about the K03 not needing a cooling off time and not having a coking problem. Early Passats and A4s with the 1.8T were RECALLED due to the problem. I ended up with a new turbo from the problem. Coking was a very significant problem with early B5 1.8Ts...
