[s-cars] turbo @ 200000

[David Giannandrea]

 This time I also sent the injectors off for a cleaning. I think it was NO2
that was the high reading.

It is perfectly normal for oil to collect in this hose. It is the low point 
of the system. It will soften the hose over time, resulting in leaks. Good 
time to inspect it, once it's off.

Replacing the 02 sensor and plugs every other year to pass inspection does 
not sound normal. My (chipped) 94 S4 has always passed the California test 
with flying colors. I'd think that there is something else at work in your 
case.
