About 10cm/4" after the turbo, _before_ the corrugated pipe, under the
black metal intake boot to turbocharger pipe, next to the air cleaner
housing... hope I've given enough clue ;-)

Another lister recently suggested that applying +12V to the oxygen
sensor wire will prevent the ECU from generating error code, also
applying 500mV or something like that to the wire will make the ECU
happily think it's running stechiometric all the time.
As to my liking, your VW/Audi techs are talking b*lls**t and the lambda
sensor was never on this car.
