Can you remind me the engine code again, I accidentally erased the first post.

I have some problem finding an image of the ECU's pin out configuration. It appears to have over 100pins - does quite match the current audi/VW ECUs (two compartments)

Can you take a picture of the pin out side of the ECU?

I have got the wiring diagram but no reference to the actual ECU outline.

This is great, I can now do a proper drawing. Most probably during the weekend.
