I have a 2006 A3 Sportthat I bought last Aprilfrom out of state. Ithasbeen tuned by APR and has a KO4 turbo, full exhaust, and ecu upgrade. When I brought the car home it passed emissions with no trouble.

On October 1the St. Louis area adoptedOBD II testing for emissions. This weekthe carfailedemissions due to the readiness of theCatalytic Converter monitor. I believe it's throwing an error code because of the high flow catalyst.Previously APR wrotecodeso it wouldn'tilluminate a check engine light for this problembut the monitor still sees thehigh flow.

Icontacted APR and was informed that for my areayou can have onereadiness failure and the car will still pass as long as there's no check engine light. I checked the Gateway Vehicle Inspection Program website and this is true. However, it also states "All gasoline-powered vehicles will fail the readiness portion of the OBD test if either the Oxygen Sensor and/or the Catalytic Converter monitors are “Unsupported”. If a vehicle fails an emissions test with a recorded catalytic converter related DTC (P0420-P0439), the vehicle will fail its retest if the catalytic converter monitor is unset". This tells meif yourcatalytic converter monitor fails the readiness test, thecar will fail emissions, period. The readiness portion of the test has to be passed before continuing.

In an email I received,APRwrote "Our programming does not disable the secondary oxygen sensor... It simply prevents the car from throwing a CEL for the error code 16804/P0420 (Catalyst System; Bank 1: Efficiency Below Threshold). The secondary sensor should still work and operate as if the car were stock, but readiness will not be passed because of the higher flowing catalyst".

I'm having problems convincing Corporate APR that there's a problem. The local APR dealer, Jon with Reid Vann has been great and is trying very hardto fix the problem. He's had the car for 4 days but can't get it to pass. I'm frustrated because I know the car will pass the particulate emissions standards if we can get to that point. Anyway, if there's anyone who doesn't have to worry about emissions testingthat is looking for a very fast clean black 2006 A3 with 28,xxx miles, let me know. I'll sell it to you for what I owe on it which is around wholesale according to Edmunds. My only other option may be to put an OEM catalyst back on and I'm not sure that would work. The crazy thing is, it's my wifes car and she never drives it fast. What a waste.

Just wanted to let the locals know that if you have a high flow catalyst, you may have some issues with the newest area emissions testing.

 

have you vagged the car?

if not i have vag... mabye you can clear it and try again


also if you are avaliable...we are having a meet tomorrow 4-5 in des peres

Thanks for the invite but my car's still in the shop.

 

Peek I really want to know what comes of this, At the meet we were talking about you because I'm looking to gut my pre-cats and want to know what needs to be done not to throw a CEL. I get my emissions done in the next few days so it shouldn't be a problem till 2010, but still would like to know how to fix it.

 

i was also thinking about this at work........ when i got the car done....... tp that is, i was throwing a rediness code, but when i got my apr tunning upgraded and tp software they had to clear all my codes......


well, when i vaged it today i had no readieness code..... might tell john that as, he told me that apr said no one in mo was passing the emissions with the apr tp software

 

turbo how much is the tp software and does it work for the piggies?

 

i think it is a free upgrade, you just have to pay reid vann 50... 1/2hr is what they call, for labor...... if it will get rid of the rediness code... you might wait till you get the piggie to get the software.... he has to clear your ecu of stored codes

 

Just spoke to John on the phone. He's tried everything and we're still failingdue to the catalytic converter monitor. He's faxed everything to APR butthey haven't responded. We're now looking atgoing back to stock with the catalytic converter. Not sure if auniversal one wouldpassor even be worth putting on. Anyone have any suggestionson a manufacturer? Thanks.

 

you need one to fit in the stock location.... so an "aftercat" cat probably won't work....


i know there were/are alot of lsX guys(f bodies) running a plug in device that is escaping me right now

 

try an 02 sim... duh, my mind isn't working

something like this might work
