2008 A4 2.0t 'lean at idle'

[David Giannandrea]

Although I read the TCB about 'lean at idle' I'm not sure whether it should
apply to the 2008 A4. I suspect this A4 has the upgraded Crankcase
Ventilation Valve, 06F 129 101K because of the model year, but haven't
checked and haven't asked a parts department if the -K version is also
superceded.

Any help on the part number or the 'lean at idle' problem would be much
appreciated, before I just blindly buy a new CVV.
