try with the valve off the exhaust but plugged in and open and close it with bimmerlink. Does it work? If so it’s the valve sticking or the spring in the wrong position. Might feel some resistance when it’s installed on the exhaust letting the ecu know which makes it stop opening and closing to not cause further damage to the flap actuator.I'm at wits end trying to figure out how to get my exhaust valve to work. It stopped working (stays open) once i installed the Ark catback. I need to figure this out because the exhaust is pretty loud, and i'm sure my neighbours don't appreciate those 5:30am cold starts
The fact that it stopped working once i swapped out the exhaust would indicate that it's a mechanical issue. But that doesn't seem to be the case actually. We've checked the whole mechanism and it seems to be fine.
Used bimmerlink to open and close the valve. It would close for a second before opening back up. Spring issue? No, because when i tried doing the same thing when the car was off, the valve stayed closed. So it seems to be software related. I have a BM3 multimap on, and i even changed the exhaust flap setting to stay closed in sport mode. Nothing

Really appreciate the suggestion man. I'll give it a shot. Fingers crossed!try with the valve off the exhaust but plugged in and open and close it with bimmerlink. Does it work?

you install the lines yet? how much different is it from stock brake feel? also love those rotors!Got these Paragon rotors on. 3.9lbs lighter per corner sounds nice

And these Spiegler lines i picked up from CSG

Yeah i've installed them along with the rotors....and so it's hard to isolate the impact of the lines alone. I can speak to the whole braking "experience" now that i have rotors, really good pads (endless mx72 plus), lines and a master cylinder brace. The braking overall feels much better. None of that makes my stop faster obv, but consistency and (quite importantly for me) feel is massively improved. Almost no sponginess/sloppiness. It's hard to know how spongy the OEM setup is until you change it. Considering the low cost of entry for lines and the master cylinder brace, i'd advise everyone to do them anyway.you install the lines yet? how much different is it from stock brake feel? also love those rotors!
The lines make like no difference in feel. The OEM lines are already metal weave with rubber outer layer.you install the lines yet? how much different is it from stock brake feel? also love those rotors!
Man I want one of those Wagner manifolds someday. What cheaper? Sorry I missed that. Bryan’s gonna scold me ?Cheaper than an aftermarket one
