Well, I wish I read this thread before I went for my second test.
For reference I have a 2010 GTI with APR Stage 2 tune, APR CAI, and APR down pipe. I do not have a check engine light on.
I went for my first drive clean test last week and failed on two counts. Catalyst - "Not Ready" and Oxygen Sensor - "Not Ready". The guy at Mr. Lube told me it was either a. because you don't drive enough or b. because you have a tune. So, thinking by some long stretch it may have something to do with me replacing my battery recently and not having driven enough I waited a few days and drove a bunch, and got re-tested today. Failed again, same issues.
So, now I’ve paid once for nothing and I’ll have to pay again before it’s resolved. So I’m a little annoyed to say the least but that’s my own fault for not looking into this beforehand. I figured with no engine light on and my car running fine I would have been good to go. Nope.
I was thinking the solution was to switch to stock mode but seems like that’s not the issue based on ferrariF60’s experience and Blakcard’s comments. Although I am stage 2 with a downpipe... Maybe I need to reflash to stock? Maybe the downpipe is causing the issue...
Any help or thoughts here would be greatly appreciated.
Thanks in advance.
