Thank you. Just found it and wanted to report. You beat me to it.

It is the "Throttle Valve Tube". I read what generally it does. Seems necessary.

So... it came with the Tiptronic. I'll assume, unless otherwise corrected, that the manual tran arrived absent that pipe.

Does that mean that the Pedro mod won't happen on the Tip, or only with some additional fabrication to accommodate that valve tube?

Finally, if you know, what exact function is that valve tube providing?

Thank you.
