Volkswagon passat 1.6 1997 - Engine speed sensor - stevep1421

My passat was missing, lack of power etc and when put on the diagnostic it showed an intermittent signal from the engine speed sensor (G28). I then purchased a replacement but cannot for the life of me find where the sensor is. I certainly cannot fid one that is the same as the one purchased and I believe that this is correct as the car registration was used in order to get the correct part.

Can anyone please help me locate where the engine speed sensor is on this 1.6 engine?

Thanks, Steve.

Perhaps a manual would be best; it includes torque settings if there are any!
