it seems to vary by smog station.
the state recognizes that computer problems shouldn't prevent you from passing, and they've set up a process to address this. but it's, as i mentioned, a process, so i avoided it.
if i'd gone that route at the outset it probably would have been easier than...
thanks for the encouraging perspectives, vince and andy.
i'm determined to get to the bottom of this. with little time, less knowledge, and limited access to tools, it's become a saga.
thanks for the input and patience, everyone!
i'll give that a shot.
many thanks for all of these tips!
(i've been concerned that the ongoing ccm unreadiness may be a sign of an expensive problem in the actual crank shaft.)
i suppose i could have performed the clear codes function with the scanner, but i didn't think to do it because it said "no codes" or something like that. (it was only when i went inside one of the menus that i discovered the message that said "ccm: not ready.")
as for the question about...
it was indeed a 9mm 12-point bolt.
i replaced the crank shaft position sensor. then i drove it about a hundred miles. then i checked it with an obd scanner. it still says "ccm not ready."
i suppose the problem could be in the wiring harness someplace after the spot where the csp sensor...
when i took a look at the bolt holding the sensor in, i originally thought it had a hex head.
i just went in to remove it and discovered that it's a star head.
anyone happen to know what size?
i got my hands on an obd scanner today and tried to clear all the codes. the ccm still shows up as "not ready."
i checked the wiring on it (thanks for the great tip, stdoubt), and it has no obvious defects.
i'm going to order a new one on monday and replace it when it arrives.

hello.
this started with a problem getting smogged that i described here: https://forums.tdiclub.com/index.php?threads/2006-tdi-golf-mk4-ccm-problem-cant-pass-smog.535324/#post-5876781
possibly salient context:
the car runs fine.
no check-engine lights.

i just checked the car with an OBD reader. comprehensive control is still incomplete.
is a VCDS likely to diagnose the cause of this problem?

thanks, everyone, for your replies.
i understand that the sunroof and alarm problems aren't causing me to fail my smog test. i shared that information because i thought it might be useful context.
the vehicle inspection report's section entitled "OBDII Monitors Not Ready" lists one item...
wow! i appreciate it!
i did a detailed (and strange) driving procedure that i read about. it's supposed to reset the CCM. not sure if it worked.
before i go to the smog shop, i'd love to meet up and see if it did.
i'm heading out of town, but i'll get in touch with you next week.
many thanks!
When I went to get it smogged, the technician said he couldn't pass it because of a CCM error. I had just replaced the battery. He thought that driving it for 60 miles might reset the CCM. I drove it many more miles than that, brought it back twice, and the error continued.
The car has...

thanks for the replies.
i drove it about 100 miles and went to retest it today. they checked the OBD2 and said the comprehensive component monitor was still not ready.
any advice?

I see that there's a stickied thread on this, but I'm having trouble navigating the responses.
If you're in the Bay Area and you have a vag-com, are you able to help me diagnose a Check Engine Light (CEL) on my 2006 Golf TDI?
Many thanks.
Really?
I thought the difference in the lubricity of the fuels causes some gaskets (or fuel pumps) to fail when you do an abrupt transition.
I've heard that they recommend you mix the fuels and change over gradually.
Thanks for the reply.
the place where i get biodiesel is no longer going to carry the fuel because of a decision, i believe, by california's air resource board.
we need to transition the car to petro diesel and would like to do so as smoothly as possible.
here are the details that i believe are relevant:
