Astra H 1.7 diesel

[Andy B]

Starting another thread for clarity 
0683 code by the pedal trick on a 1700 diesel Astra H
Googling says Glow Plug Control Module to PCM Communication Circuit anyone any ideas. My diesel Astra G gave a similar fault code which turned out to be a failed glow plug, but the car used to stutter a little for a minute after starting, this car though apparently is running fine from cold.
Suggestions on a post card please.

3 glow plugs at 3 ohms & one open circuit  New plug ordered from Vx, see what happens when fitted this afternoon!

Aren't pedal tests/tricks great!

Too many pedals

A £13 glow plug later & sorted.
