2014 a5 CEL and code check

[groovymaniac]

So I just took my stage 2 tune off my a5 to bring my car in for service, and on the way home the CEL popped on for seemingly no reason. The code I have is 013f, and after some searching I can not figure out what the error means. The car is running fine with no issues as far as I can tell. If anyone has any insight as to what that may be that would be great. Thanks.

I'm not sure what the code means, but are you running an O2 spacer on your HFC/TP? It could be that your car is warning you about the increased air flow. I would recommended not taking in your car for service with a CEL as they may begin to poke around. GL!

Yes I am running an o2 spacer, what would I have to do to clear the CEL and have it not come back?

[JesssMooo]

It's possible that the o2 spacer didn't do the trick for your setup. I've heard of some spacers working for some but not others. Maybe clear your current code and watch for how long it takes to come back, maybe you'll be able to make it through your service without detection. Another option is to try a different spacer, clear code, and hope the code doesn't return.

Alternatively, you can take your car to a trusted Indy shop and not deal with the stealership for service. It'll also probably be cheaper.

I've got the audicare package, have replaced my clutch and flywheel with a stage 2 setup, and have had minimal issues with the car. Even if they asked questions about the HFC and the CEL would I still be covered for all routine maintenance work for the 35k? Any idea on what would happen to my remaining warranty?

If the dealership finds that the modifications on your car are causing the CEL, they will not cover the repair. And in the case of your fault. P013F - O2 Sensor Delayed Response - Lean to Rich Bank 1 Sensor 2

Check the Oxygen Sensor 1 After Catalytic Converter -GX7-. Refer to → Chapter „Oxygen Sensor 1 After Catalytic Converter -GX7-, Checking“.


Sounds like your 02 spacers seems to be the problem. What tune do you have on your car, I suggest you get one that eliminates secondary 02 sensor faults.

I have the APR stage 2+ tune on my car and have no CEL or issues with the tune on, but when I got the tune flashed off is when I had this issue. Should I just try to swap out the o2 spacers and clear codes and hope for the best?

I have stage II as well with the O2 spacer. No problem with cel even before tune. I have 4 programs on my APR tune and all I did was switch over to stock mode which deletes the test pipe and I'm good for emissions. I bought my O2 spacer from 034 Motorsports but I think they discontinued making them.
