Hi,
Does anyone have a guide to long code the 2022 S3 exhaust flaps open?
Thanks,
Paul

Got this to work yesterday. Start the car, put it in Dynamic. Listen to hear if the valves opened and the exhaust tone changed. Shut the car off, turn the ignition back on without starting it, pop the hood, attach OBDeleven and connect.
Go to Control Units, 01 (Engine), Long Coding, Byte 9, Bit 2. Check or uncheck it (can't remember which, just whatever is the opposite of what it was set at). Start the car, drive around in Comfort like a boss.
While you're at it, go back to Control Units, then A9 (Structure Borne Sound), Adaptation, and your only option is "Volume of structure-borne noise actuator" which you can adjust from 0-100. Set it at 0 and never think about it again.

Oops, I looked back. Soundaktor was too much after the res delete. Stock, it might sound better with flaps open and Soundaktor on. I might set it back to 50%, it does add a nice harmonic to the res delete exhaust tone.

I've disconnected the flaps when open, and done a res delete too.
Now that this coding is known I might reconnect them and keep open with OBD11.
What do you mean with "soundaktor was too much with res delete?" I've never changed it after removing the res.

I get error 31 when trying long coding, the module is not protected by sfd, is an access code required?

What do you mean with "soundaktor was too much with res delete?" I've never changed it after removing the res. I just meant that there was too much “vroom-vroom” with BOTH Soundaktor on AND res delete, especially with all 4 pipes always open. At first I thought the res delete with valves/flaps open at all times sounded fine without help from the Soundaktor. In the end I turned Soundaktor back on and left the valves/flaps at their default setting. That way it’s quieter in comfort mode (res delete makes it louder than stock, obv) and louder in dynamic mode. In other words, imo, either do a res delete and leave everything else as-is, OR keep the resonator but open the valves/flaps at all times. This allows you to still have the quieter option (comfort mode) for when you need to drive great-grandma to the store. |

Otherwise get that little kit to waterproof the contacts down there. Advantage of doing it through software: you can easily disable it once in a while to let the flaps flap so they don’t get stuck open or closed. Is that something that happens? I don’t want to find out. |

Thank you for you reply, yes I've tried it with opened hood, my idea was to long coding then reattach the flaps connectors.
Maybe I need to reattach them and then try the coding.
I've used a "fake male" connector to make them waterproof when disconnected.

I had the function not available msg on my obd11 app trying the long coding for this, almost all the apps worked no probs, SFD auto unlocked, bonnet was open etc.

Same here. Error 31 (function not available) when only ignition is on and error 22 (Function cancelled., marginal conditions have not been met) with started engine. Did something got changed there? I'm trying this with an Audi S3 from Q4/2022.

Jop, die Codierung ist quark. Geht nicht. Weder bei Audi, noch bei Cupra, noch bei Golf.
EN: Yep, the coding is junk. Does not work. Neither for Audi, nor for Cupra, nor for Golf.

That sucks.
Hopefully someone can give some update if this feature will be included anytime soon.Bought it for this sole purpose so if it doesn’t work it’s pretty much useless.
Even paid for Pro version

don’t hold your breath, this like start stop is part of the emissions targets mechanisms and is now no longer able to be manipulated via the OBD port. I ended up getting the spring removed and the valve tack welded open. reversible in 20 mins by an exhaust specialist.

You can just unplug the servos once they are open. Exhaust valves are then open permanently.
However, on my S3 (2021) that did result in the Soundaktor being on maximum volume in all driving modes (which I didn't want, so I plugged them back in).

Looks like I’ll just go to a tuning shop and have it reprogrammed.
I know you can just unplug them but I would like to get it don’t properly and see how much sound changes before I go for aftermarket exhaust.

honestly not that much. i had it down after a resonator delete and i couldn’t tell any difference. The PPF on the 8Y really restricts any sound

I know you can just unplug them but I would like to get it don’t properly and see how much sound changes before I go for aftermarket exhaust. You should definetely just unplug them first to get to know what it will be like. The difference isn't really noticeable when you are sitting in the car. From the outside the sound is more dull with the flaps opened permanently. You can get even a little crackling sound when reving in neutral or parking. But overall it is not really louder when you are driving. |

This coding solution is not working anymore, was stopped in 2018 by VAG

I have a 2023 S3 and did the long coding. My car has the resonator delete too. Yes you notice it's a tad louder at low RPMS, but in my case, I lost the pops and bangs on the downshifts (sweet spots is 3k and above). I reverted back to default which byte 2 checked! (unchecked is opening the valve).

I can't write the coding, I always get an error.
I also have a res delete too, but didn't lost pop & bangs on downshift.
Going to mount milltek catted downpipe anyway..
