Does that seem out of the ordinary?

Default did ya do anything else? (edit)

Keep in mind, the ECU will store codes that won't necessarily trigger the CEL, so you may have something in there about your fuel trim, and it simply hasn't gone far enough out of spec/passed enough duty cycles to register a CEL.

You got a vag? Should log your fuel trims.

Default how much have you actually driven it since then? the sensors need to undergo a certain amount of

cycles before they will throw another code. I know many people that play that game all the time! ;-)

At least 10K. Going to VAG again this week and see.
