B5 1.8T Engine Diagrahm
So, the previous version of this diagrahm I have is labeled all wrong, so I was trying to get this filled out right, i'll start it with the easy ones I know and hopefully with everyone's input, it can be complete (and correct) shortly. Thanks.[/align]

RE: B5 1.8T Engine Diagrahm
Ok, I found my Bentley manual page (for B6, I'll match up to your B5 diagram best I can)
Thing on the far left (unnumbered and cut off in your diagram) is the secondary air injection pump
3-EVAP purge valve (N80)
7-Combination valve for secondary air injection
9-Goes to brake booster
13-Secondary Air Injection Solenoid Valve
18-To EVAP leak detection pump
19-Recirculating valve for turbo
21-Vacuum diaphragm for boost pressure regulation
22-N75 (Wastegate Bypass Regulator Valve)
23-DV
24-Pressure regulator valve for crankshaft housing ventilation
