replacing the timing sensor {see graphic}, which is the procedure to properly register the new one?
Could not find the procedure in the workshop manual.

there is a mark in the body near the front bolt
this must be with the mark in the cylinder head
it is not exactly a mark...it is a corner made from 2 surfases
thanks Nick

The UK manual mentions a "reference notch" in the middle of the bolt hole near the electrical connector.
But not sure that matches anything on the head???

I found some notes how to mound this sensor properly, from my friend in Italy, concerning the sensor for the Evo2.
I'll translate them tomorrow {I'm by the sea right now with the family} and I'll post it here.
I believe the holes must coincide - see attachment - with engine at compression phase for the 1st cylinder {at PMS}.
I believe it can only be checked with an oscilloscope but ... I have not any to confirm this.

The "reference notch" I mentioned is below the "8", look forward to your translation as the diagram is pointing elsewhere

well, according to the notes from the guy in Italy, the proper setting is
- to have the hall sensor at 50 degrees from the PMS for an oem car.
Or, by
a} placing the 1st cylinder at PMS, compression phase
and
b} having the two holes in the red cycles in the graphic {4 mm diameter holes} align!
Thats all
Though still waiting for a confirmation
ps.
PMS = higher dead point - do not remember the term in English, sorry

Excellent, thanks...I'm about to check the valve clearances on mine so will check this at the same time

when you check this sensor with 1st cylinder at TDC compression phase, could you please take a picture from the camshaft? I'm interested on how the cam notches will stand - towards inside or towards outside the engine head.
Now you mention it I think I must check valve clearance in mine too. I hear a couple of valves knocking - one for sure.
Nick
Will have a go
