Do you intercept the glideslope from below? That is to say: do you see the glide slope indicator (little diamond) on the top of the instrument, as you wait for it to gently come down when you enter the ILS?
I suppose it could be a layman’s error to intercept the ILS from too short a distance, so just veryfing that. It’s not impossible to intercept a glideslope from above (pretty standard in Amsterdam Schiphol for instance) but it sure is less comfortable.
