if this were so, then why have i been able to get the readiness monitors all set previously? personally, i dont think I'm getting the drive cycle right, because i haven't once been able to follow it sequentially. so I'm gonna swap exhausts with my stocker and see if the ecu just doesn't like my tuv certified 200 cel cats

ha, some funny sh*t, right? imagine that was in '76. think it's better now? i think not

 

SUCCESS!

i am wearing a decorative pointed hat, and have ordered cake. once again, all is right with the world

 

What did you have to do?

 

drive....

....and drive.....

...............and drive.... some more lol.

 

Nice!

 

It's a good feeling !

 

I've experienced CELs in several cars that have come and then cleared themselves in a few days. Given the nightmare of the readiness prep on our cars, this makes me wonder if the approach of fixing the potential issue and immediately clearing the code is suboptimal. Could a better approach be to fix the potential issue, then wait to see if the CEL clears itself and thus avoid the readiness issue caused by the OBD code reset? Is there any info out there on how long it takes for a CEL to clear on its own if the underlying issue is resolved?

 

jay couple of points re the codes and cels ( though I'm sure you know this...) is that any stored soft code is enough to fail you. so even clearing the code ( fixing the issue ) isn't enough to allow you to pass the "test".

thats exactly what is so insidious about this whole process! is that you can have NO "problem" and still have the readiness monitors showing "not" ready!

the whole thing was a cluster*ck, but my perseverance has paid off.

and z06801.. yeah, what a relief and its great to be "legal" and reg'd for 2018.. i just hit redline to celebrate.. after eating cake ( but not humble pie ) woohoo!
