Ok all you Audi fans. There is an Audi technical bulletin covering a condition that not only causes a smoking condition when the temperature drops below freezing but also causes blown cam seals and valve cover gaskets. Anybody out there hear of TB C1504-02 ?

No, but it sounds like there is a crankcase vent valve that suddenly ain't venting the crankcase, don't it?
Maybe this applies?

Exactly. Sucker valve, vacuum boost valve whatever. This thing cost me a lot of money and confused a lot of mechanics.
