Exhaust Flap code ?

PaoloV · 10-28-2022, 03:15 AM

Good morning everyone. Someone tried to code this . I'm trying to figure out if one of the three combinations opens the exhaust flap

It is possible that no one has tried

I've heard that you have to drive around for 25 minutes in sport mode and it will only work to flip it when its already open. you cant open it just lock the state.

Ok . thanks for the information

Np man, I've heard of people pulling the fuse while open in sport as well

Not sure if this works for all models but could be an option:

Search the forums. There are a few different ways to accomplish this.

Pull the fuse
BimmerLink coding

It is not possible to do it with BimmerLink. All that does is temporarily open the flap while it is running. Once you shut down and and restart the flap will be closed. People use BimmerLink to open the flap and then either pull the fuse or disconnect the wire. It is not possible to do it with coding as far as I have seen.

Sorry for the confusion.

You are correct, BimmerLink only allows opening and closing while the app is running. Once the app is closed/disconnected the vehicle computer takes back control of the flap. So if you wanted it open all the time you would use BimmerLink to open it then pull the fuse or disconnect the cable running to the exhaust itself.

Thank you. I know all these possibilities. I use BimmerLink when I want to have the drain open. My thought is that if using BimmerLink the download opens , it means that it acts on some encoding parameter , I wanted to find the code and use it with BU. It seems that the codes above in the screen are three different possibilities to act on the discharge , but I'm new to encodings for this reason I was looking for help. Another way perhaps could be to modify FA by adding Msport exhaust and try .

Do what you want, but consider these three things:
- opening the flap constantly will make the idle sound louder
- opening the flap will mean the turbo will take longer to spool up, so less power off the line, i.e., a slight delay. It is normally only opened when there's enough exhaust gas velocity to fully spin the turbos and lets the engine breath better at higher RPM.
- opening the flap will slow the engine warmup, decreasing efficiency until warmed up.
