Is there any way to "force" it open. I called my dealer and they said everything is fine w your car it'll open when it wants to and that's the problem it never wants to.

So the dealer can activate the valve and put it in to what's called "installation position" this will move it to 90% open. Then it can be unplugged. Not sure if they will do that as it's completely up to the tech.
Like at my dealer I worked for, some techs wouldn't touch a car with mods or anything. Me, I went to work to make money and I didn't give a flying fuck what was done to the car.

My car is base and I have done nothing but that damnnnn valve never wants to open. So I might talk to them when my service is due, but is there any way to force it open like push it or turn that clip thing.

It will break, many have tried this and all have failed.

Afternoon, I have a 70 reg 235i and my car seems to pop a little bit sometimes on start up but then nothing when I rev it regardless of what driving mode I’m in

I’ve heard all the pre 2020 reg car and they all pop and bang as standard when at a standstill

Is this to do with the introduction of the opf filters or has it been coded through the ecu because I was wondering if removing the opf filter along with the back box would restore some of the popping

Cheers

You need a burble tune for them to be audible while driving.

I’m not too fussed on it while driving I was more referring to while being stationary

Then yeah, you'll hear it more as you free up and open up your exhaust

[Tombrunskill]

Has anyone tried or had a pop and bang map done to their car? Intrigued to see if it’s possible or safe to do so with the cat and opf filter

Uhm... What I've figured is that for the exhaustvalves to open your cars "engine sound" option has to be set to (not sure about the translation) "Drivemode dependent". Then when in sport and the car warmed up, the exhastvalves open.

Depend exactly when in 2020 it was produced. Post June 2020 ECUs are totally locked, on a company Finland is accessing them atm.
