Hello Everyone and Happy New Year! Back on the board with my 2015 S3, the same one that had transmission issues that you guys helped me out with, and AOA ended up replacing under goodwill.
Now I have been having misfires for the last few months. Let me list the issues // problems in proper (or as close to) JPPSG:
1. 2015 Audi S3
2. Car is modified - Unitronic Stage 2 ECU Tune and Stage 2 DSG Tune as of 60,000 miles. Aftermarket catted downpipe with O2 Sensor still in place, and cold air intake.
3. Problems started around 73,000 miles. Here's the latest scan:
4. Once again the CEL went on and i ran a scan. I got the above misfire codes and a "small EVAP leak" code. So i changed the N80 valve, spark plugs and coil packs, all parts were OEM and stock to car (S3). Cleared the codes and was good to go for about 73,000 miles. The CEL went on again with misfire codes. This time i went with "upgraded" coils (RS3) and plugs (colder RS7), reset the code and was good to go for a few miles. Then AGAIN i got a CEL.
With my mileage i suspected carbon buildup. I went to a reputable car repair shop (not sure if i can post their name) and they ran a diagnostic. I DID not tell them i suspected carbon buildup so as to get a "transparent" diagnosis. They said the car needed a carbon cleaning and showed me photos of what appeared to be a bat cave (probe photos via intake manifold). I went ahead with the carbon cleaning and i noticed a MUCH smoother idle and acceleration. These guys also replaced the injector gasket and the intake manifold gasket as well as replaced the water pump (had a small leak and they gave me a GREAT deal on replacing it since they were in there already).
That was about 3,000 - 4,000 miles ago and here we are with MORE misfires. The above scan is the latest.
5. Here is what i am thinking about doing: flash car back to stock. Perform a smoke test and find the cause of the EVAP leak (need to buy a decent smoke machine that won't break the bank, opinions are welcome). I was thinking it might be the PCV also? Maybe replace that?
Thanks for any help!

End----------(Elapsed Time: 01:41, VBatt start/end: 12.2V/12.2V)-----------4. Once again the CEL went on and i ran a scan. I got the above misfire codes and a "small EVAP leak" code. So i changed the N80 valve, spark plugs and coil packs, all parts were OEM and stock to car (S3). Cleared the codes and was good to go for about 73,000 miles. The CEL went on again with misfire codes. This time i went with "upgraded" coils (RS3) and plugs (colder RS7), reset the code and was good to go for a few miles. Then AGAIN i got a CEL.
With my mileage i suspected carbon buildup. I went to a reputable car repair shop (not sure if i can post their name) and they ran a diagnostic. I DID not tell them i suspected carbon buildup so as to get a "transparent" diagnosis. They said the car needed a carbon cleaning and showed me photos of what appeared to be a bat cave (probe photos via intake manifold). I went ahead with the carbon cleaning and i noticed a MUCH smoother idle and acceleration. These guys also replaced the injector gasket and the intake manifold gasket as well as replaced the water pump (had a small leak and they gave me a GREAT deal on replacing it since they were in there already).
That was about 3,000 - 4,000 miles ago and here we are with MORE misfires. The above scan is the latest.
5. Here is what i am thinking about doing: flash car back to stock. Perform a smoke test and find the cause of the EVAP leak (need to buy a decent smoke machine that won't break the bank, opinions are welcome). I was thinking it might be the PCV also? Maybe replace that?
Thanks for any help!
