That would be AGZ. I cannot answer that myself, however Adey might be able to help, based on his >>thread<<
Thanks yes it is the AGZ one I need. I had mis-read thread http://www.clubgti.com/showthread.php?253456-Whats-the-difference-between-the-V5-Engines-AQN-amp-AGZ Hopefully an ebay seller is measuring one for me today.
Did you get a measurement in the end? VR6 12v M3.8.1 "VDO" throttle module was 70mm the last time I checked.
Just arrived today. TB off a seat Toledo 2.3 v5 2000 reg. 70mm at the rear edge. 65mm at the plate so it's a 65mm TB.
