I'm retrofiting climate control on my B4 TDi, almost all done using S2 schematic, but I can't seem to find any specific schematic for TDi. I'm still missing idle control for ECU, compressor speed sender wiring and proper radiator fan wiring. I know s2central.net had some AC schematics for TDi, but that part of page is missing in s2central.com. Anybody maybe have a copy of that part of site or any air con schematics for TDi or any 4cyl or 6cyl engine?
