That's the one. The yellow cylinder thing with the fat steel braided line
coming out of it.

I believe the device in question is nicely visible in the lower right of
this picture:

It's the part (one of them!) that makes it really hard to raise the air
box top to change the air filter.

In this photo it is yellow.  This is not typical.

Of other amusing value, I suppose, is that this photo shows every single
component unique to CIS-E as used on the 5 cylinder Audis.
