what adaptor are you using? i'm using OBDLink MX+ with BimmerLink and can't hear it opening or closing at all. Also when i hit "Open" it goes right back to "Auto"...
Same adaptor. Try what homerrr suggests — in the meantime I'll check my settings to see if they match his suggestion.
yeah lmk your settings when you get a chance. thanks

My settings are similar to homerrr:

Type: electric
Timeout: no
Slave present: Automatic

Definitely seems to work.

Just done mine using BimmerLink with the above settings. I could open and close the valve with the engine off. Pulled the fuse and now to live with it a bit and see how it is

Would be nice to have some way to manually control the value without needing to connect the ODB adaptor and use my iPhone which is a pain.

Are there any downsides to leaving the ODB adaptor connected all the time? I notice it’s able to draw power through the port when the car is shut down. I wouldn’t want to have it draining the battery when the car isn’t in use or does the port power down at some point after the car is locked?

I've had it plugged in for weeks (due to laziness) while I'm using the car "normally", no problems noted.

So to keep the flap open, it has to be done each time the car starts using the adapter and the iPhone app? No way to open it using Bimmerlink and then pulling the fuse to keep it open at all times with the adapter removed and not having to do the entire process each time?

Yes you can do that. Open with BimmerLink and pull the fuse. I didn't do that but I know it's possible.

So is it fuse 203, 223 or what fuse is it exactly on the 40i?

Damn $32 for the bimmerlink app? Wtf

Also if I do open it using the bimmerlink app, how do I test the difference in sound between open and close? Also is the difference only in the sport mode or comfort also? Lastly do I have to keep the car engine running while using bimmerlink or put the car in diagnostic mode?

I haven't pulled the fuse but I know you can do it that way, maybe someone that has pulled the fuse can jump in and mention the correct fuse.
Not sure if there was a difference in flap changing ability between sport and other modes, but you can hear and feel (hand in front of right side pipe) the difference when opening and closing the flap with the engine running, no need for diagnostic mode. Once the fuse is pulled it'll be open in all modes for sure.
$32 for the app and some for the adaptor, if you don't already have it. To be honest I bought the app to play with the valve and haven't used it since. Flap is still in auto.
There is a way to make it happen without bimmerlink, it's on the forum too somewhere, it's going to require you sitting in the trunk, ready to pull the fuse while someone is driving under circumstances that'll open the valve (sport mode over a certain speed and/or a certain RPM). Worth $32 to not have to do that....

I’ve used BimmerLink to open the flap then pulled the F203 fuse. Once the flap is opened and the fuse removed I can confirm it remains that way until you put the fuse back in and put the flap to auto again. The fuse card seems to indicate F203 also supplies a circuit which looks like the rear wiper from the picture on the card but my rear wiper works fine with 203 out. Not sure what else might be effected by having the fuse pulled.

Yes I agree that $32 is worth it. What does Auto mode do on the flap? Buying it now.

Just so that I don't screw anything up can you send a picture of where exactly this fuse is and how do I get access to it in the trunk? Anything I should be aware of or cautious of before, while and after doing this fuse pull?

As discussed and answered many many times on this forum, flap cannot be coded (or at least no one has ever indicated any such capability to date). As such, BimmerCode is not useful for dealing with the flap.

However, BimmerLink app (completely separate app from the same developer as BimmerCode) can be used to control the flap after starting the engine. That, in turn, can allow permanently opening the flap by either fuse removal or flap solenoid cable disconnection with flap in open position in either case. There are also mechanical means to permanently open the flap that don't involve software, fuses, or cables. It is also possible to open the flap by driving and then pull the fuse during the drive.

Hi guys, I did this with my son pulling the fuse while driving in sport+ M2 and having RPM go above 4 at about 40mph. Super easy. I'm not quite sure it worked though. I would download bimmerlink, however I dont see it in the android Play store US. Is there a way to see the flaps open? Someone mentioned you can feel the air/heat coming from the right exhaust. Is that true? Would the air/heat come out of both exhausts?

Thanks yall

BimmerLink is IOS only. https://www.bimmerpost.com/forums/sh...php?p=25620783

I don't have a good sense of how to determine that the flap has opened up at speed except to listen for it, but if stationary, you can easily see it by shining a light into the right hand exhaust pipe. You can also hear it if under app control. You can also see the solenoid move if you're under the car. And yes, you can feel exhaust flow when open and much reduced when closed. And yes, if conditions are such that you would see steam, you can see it as well.

Anyone notice , after removing the valve and leave it open , regardless comfort or sport the entire car drones really bad
Even the front row at 1600-2000 rpm , especially cruising on the highway the drone is really really loud, almost as if itís been straight piped

It's not too bad. Yesterday I was backed up to wall and the drone was bad....normally it's a pleasant aggressive sound.

Later this week the BMS intake and Dinan piggy goes on....we'll see how the sound adjusts at that point.
