I noticed that one of the ports to a solenoid on my motor was broken. The solenoid is mounted near the exhaust valve cover near the 4-5 cylinders. It is bolted to a air chamber of some sort and opens a flap to the box.

I haven't had a chance to look at my repair manual to see what it is. Can anyone tell me what it controls, if it affects performance/emissions/etc, and if it is worth trying to find a used one (i.e. is this something people remove from their cars?).

The solenoid is pictured below:

And here is the best pic that I could find online of the location of the solenoid. It is just below the cruise control cable bracket near the 4-5 cylinder just outboard of the exhaust valve cover.

Exhaust gas bypass valve for #2 turbo.

^yep pretty sure thats right^ so it pumps up the actuator to pre-spool the second turbo before it comes online completely - worth fixing, it could be giving your second turbo a hard time
