Please Help - Catalyst Monitor Inc - not ready
 

Hi, I have a 2004 A4 3.0L Quattro Avant. I live in California.

Recently the Check Engine Light has been on. I have to get a Star Certified Smog Check soon.
I reset the codes/monitors and 7 of the 8 are ready, the only one that is not is the Catalyst Monitor. I've driven in various conditions for over 300 miles the past 2 weeks and it's still not ready (CEL is still off, which is good).

I read somewhere that 2001 and newer cars can have 1 monitor not ready and still be able to pass the smog check, is that true? And if it's true, does that apply for a Star Certified Smog Check station as well?

How can I get it this last monitor to complete the drive cycle and have all 8 monitors ready?

Any help would be much appreciated. Thanks!

I'd suggest bringing it to an Audi shop and have them connect with VAG COM to force the system readiness. More info here if you want to do it yourself: 2006 Audi How to Complete a Drive Cycle and Get Monitors READY.
