fiasco

Yeah, everybody laughs about having to have the fan relay and solenoid functioning for the diode trick to work...but when you're desperate to get a car functional and inspection sticker ready, it's tough to get to the fine print. So I'm going to put this here: MAKE SURE YOUR SAS FAN RELAY AND SOLENOID ARE FUNCTIONAL BEFORE DOING THE DIODE MOD!!!!!!!!!! Turns out my Hecho en Eire relay had a smoke escape issue (the Irish relay was no good). Once I put a new aftermarket relay in (Hecho en Deutschland from eEuroparts.com) and cleared the codes, I now have nearly 100 miles of stop and go driving w/o the P0410 code. Unplug power from relay to SAS fan. Plug vacuum lines from solenoid to air pump check valve. Be very careful of your 17-year-old vacuum tree, that plastic is brittle.
