Auto parts stores aren't allowed to use or rent code readers in California any more, so unfortunately that option won't work. I have not hooked up the demo of vol-fcr again, but neither of my OBDII tools see the CEL, so I am pretty confident the light is for the transmission and not the engine. I went through that before, when I had one code for ELCD and one for transmission, and my code reader only saw the ELCD code. That issue is fixed and that code has not come back.
I guess I should hook up vol-fcr again and see what it says. That software is a big PITA - largely because it makes me mess up my VAG-COM/VCDS software so it'll see the cable. :grr:
The "symptom" of the light is the same as it's been since I got the car... when I start the car, no CEL. About 5-10 seconds after the car has been running the CEL flicks on. Previously, there was only one code stored for the PnP switch (eg "range sensor fault") but it survived numerous battery disconnects. I'm pretty sure it's burned into some NVRAM and needs to be forcibly cleared at this point.
The good news is that after idling for about 5-6 minutes tonight (with new coolant hose & coolant) and shifting through gears to circulate transmission fluid the SERVICE light went off of its own accord, so now I just have the CEL.
I'll torque down the wheel bearings tomorrow and see if some friendly open-on-Saturday repair shop will reset the code. I doubt it. Those guys have a fortune in their tools and charge for them, especially since the state outlawed parts store code readers. Now the average citizen has no choice. :( Sadly, since I rarely take cars anywhere for service, I don't have a relationship with any of them.
