they tested all the sensors (all clear) tried a new ecu unit still code 42 done a few other tests and said i needed a new convertor new speedometer
had a new one fitted still the od light blinks
they have now done another diagnostics level 1 to 10 i think they said and they have come up with a voltage fluctuation on the overdrive and i need a new piece between the gear box and engine torque i think they said
if anyone else has had a similar problem or know anything about this subject then please enlighten me
almost forgot the car drives great and the gear box is really smooth

thanks for any help much appreciated

Is it an n/a or a tt?

For US-spec, code 42 is "No. 1 Vehicle Speed Sensor Signal"?

Unfortunately I haven't heard of this specific problem before, but I'll ask a couple of friends I have with auto tt's. Please be patient as this may take a few days for me to get in touch with my buddies.

Also, please keep us informed - as I have a 6spd, I haven't had this code before on my mkiv.
