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 ?

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