Here is a link to the original codes and methods, but later versions since 95-97 have variations all on the same theme;

Later models don't always need the light added as they flash the code on the glowplug light itself, even later versions use a 4-digit code and the mast few years also had genuie OBDII sockets down by the drivers LEFT knee under the dashboard.

Thanks for the reply. I did see that site but I don't seem to have the same layout or an engine one.

Can you elaborate on that ? The box is mounted upside down so you need to invert the diagrams, maybe that's the problem ?
