s3 not passing emissions

Hey Guys, first time posting here and sorry if its the wrong place. I have a 15 s3 with a cts catted down pipe and awe track edition cat back with afe intakce. I had the downpipe put on over a year ago and instantly threw a cell. I wasnt to worried because i just had my car inspected. So its time for my car to get inspected since i am over due and wont be able to register my car with it not inspected. I bought the o2 spacer to see f that would clear the cell but it didnt. I had the check engine light come on about an hour after it was cleared. Soooo i said okay well now i will need a tune to clear the check engine light and get it inspected. I had my car tuned on Wednesday and drove about 80 miles since then. I went today to get my car inspected and it failed again. Not sure if anyone has had this happen to them before or can advise i should probably drive it more and let it set?

Thanks!!

If you're passing emanations with a totally extraordinary ECU, at that point Dinan is in fact bamboozling the discharges test except if they return your ECU with precisely the same tune and boundaries as the ECU you used to pass outflows. Other Dinan sellers that administration S3s may have discovered their own in house fix also.

You will want to flash back to stock. Need to drive the car around as well so all the ecu test pass internally, then you should pass normally. Make sure no codes are stored as well.
