I did the A32-A37 diode trick on a friend's '98 S70 that was throwing a P0410 CEL (SAS). At first, I was afraid because it wasn't passing the drive cycle readiness checks - this normally was done within 30 miles of an ECU reset. After the diode, it took 165 miles of driving but it finally did complete the readiness checks and the CEL is long gone (remember, if the readiness checks don't complete, it can't be smogged!).
Thank you for taking the time to figure this trick out.
