I don't see any other open connections, and I couldn't decipher the PET - since it shows everything exploded and not actually on the motor.

Do you mean the T looking up at us?
What about the connection to the AC valve on the cross brace - hard to see if the connection is complete on the back side.

Winner-winner, chicken dinner!

Thanks, Roger. I might not have ever found that.

Next question(s): What is the effect of having it missing, and what size is the line?

It increases the tick over to compensate when the AC kicks on.

It does indeed go to the AC valve Shawn. Check the orange lines in my photo to the left. I believe you will have a HUGE vaccum leak if it is not connected and your AC willnot work though I have not tested that assumption.

So I thought hanging a valve on the cross brace was an exclusive S3 thing.
I never liked the concept, it always seemed like Porsche did it as an afterthought.... just slapped it on there to save time and energy.
I relocated my diverter valve just to get it the hell out of the way.

I'm pretty sure there's a vacuum leak - I think I can hear it at times. But, the AC blows ice cold.
