Let me preface this reply by stating: I'm not an FD guy.
I have messed around with a few FD throttle bodies though...
If we're all talking about the big blue spot on the "bottom" of the throttle body, then I can only guess it's some weird dead area.
I believe there's a largish hole right in that area?
Don't quote me, but I think it's some bypass passage for idle control?
So the big blue spot is caused by excessive accumulation of the wiper fluid and / or not enough airflow to keep it off the "floor"?
I wonder if you've got the same kind of residue in the throttle body elbow that precedes the throttle body in the intake system?
It looks like the blue spot could not just be isolated to the throttle body?
