Regarding the 428 question:

The link below shows a 328 exhaust, which should be the same as a 428. A flap actuator is on the parts list.

Can someone enlighten me on how to do this golf tee mod on my F30 328i? Is it the same for both 335 and 328? Or in other word, can I just use the OP post as a guide for this mode?

Thanks!

Finally got a chance to read the whole thread! I decided to go with unplugging the black thing instead of doing the prying springs. I'm just wondering if anyone experience a lost of low-end torque? I read some other threads and quite some people complain about lost of low-end torque.

Thanks in advance!

i may have gotten this the wrong way?
when i start the car(cold car), its loud as hell, but only smoke and warm air coming out of 1 pipe. after half a minute, i hear the exhaust valve opening, and smoke/heat starts to come out of the second pipe. does it just open halfway beacuse im idling? pretty confused about this, cause i have thought about doing that mod also.

There is a thread on this forum that points it out. It's an electric actuator which makes it a little trickier than the old golf tee mod.

If you drive in sport mode, it bypasses this anyways (so it's pointless to do in this case).

So, you're saying for 340i , the golf tee mod is not necessary ?
{Provided you drive in sport +}

So, if I'm in sport +, the exhaust flap is always open?

I searched a lot and couldn't find any how to for f30 golf tee mod.
This thread has a how to for e92 only.

I turned on the car, left it running on sport mode while I coded the dimming sensitivity on the mirrors, got out of the car and noticed the flap opened, then I proceeded to unplugged the connector, wrapped it around with electrical tape to prevent crap get into it. I will post back my feedback about it.

My understanding is in sport or sport+ the flap is open. In Economy over a certain RPM (number eludes me right now) it opens as well.

The thread I saw involved removing the motor from the valve, and wiring the flap open.

It's pretty simple to do. Just start the car and wait around 40-45 seconds until you hear the valve open then just go underneath the left exhaust tip and pinch the clip on the connector to unplug it (hold your breath so you don't inhale the exhaust lol). After that I'll just wrap up both ends with some electrical tape.

I did it when I first got the car but it ended up being too loud on cold starts with a resonator delete so I put it back.

I started up my car , put in sport +, and waited a minute , then went to check the left exhaust (looking from behind the car) and noticed there was a black circle flap that closed this left pipe.

The right was open.


So, I drove around in sport+ 2-3 mins , then checked again, still flap closed.

Then I drove 12 mins in heavy sport+ mode, some highway, then checked -- still flap is closed!

Wtf - am I missing something ?

I figured (unless you unplug the canflap) it was based on engine load whether it was open or closed.

You you just unplug the connector of the valve while the car is OFF it will leave it open.

A lot cleaner and easier then rigging wire.
I think unplugging the connector will cause a code stored

Tried the wire method and the plug method. Theyíre the same thing.

HOWEVER with the unplug, the valve simply got stuck at the halfway mark (half open/closed) and when I plugged it back in, it didnít move anymore. Didnít thrown any codes with many visits to the dealer. (By the way I had the plugs completely secured with electrical tape on both the connector and the valve actuator).

So with that said, I manually opened the valve and wired it as in this guide in under 10 minutes. Removing the spring allows you to independently move the valve. Even if you wanted to reinstall the spring, you just need to realign the valve to the actuator.

Have you been to reinstall the spring ? My spring was broken so I bought a replacement with the intention of installing it. Except the valve and the actuator slots are now misaligned in both complete open or close position that its not possible to reinstall the spring ? Looks like there may be a special setting that put the motor side in "INSTALL SPRING MODE" as right now it goes like an extra 1/8" of an turn misaligning with the valve side.

No its the exact same. Whether you're 8AT OR 6MT doesn't matter.

At start: Remains closed for about 11/2 - 2 minutes then opens.

Eco Pro: well, I can't say I ever really use Eco mode but I find it behaves similar to Comfort except the flap is closed at low RPM.

Comfort: flap is open halfway at low RPM, opens fully at (correct me if I'm wrong) 3,000 RPM.

Sport/Sport+: Flap is open throughout the RPM range and at idle.

Yes I ended up reinstalling the spring after my tune and DP. Currently, the valve is functioning normally.

I had to move the valve manually to line up with the actuator. You pretty much won't be able to move the actuator. If you sit the spring in the groove for the valve and then rotate it until it aligns, it should work. If it doesn't, try flipping the spring.

With a little patience it will sit eventually. Just make sure it's not sitting outside the groove, if the actuator moves the spring and it's not in the groove, the spring will fall off.

Thumbs up

I managed to build a prototype circuit board coupled with a remote to open and close at will the exhaust flap.

Press the first button it will open the flap ie. manual mode
Press the second button, it will revert to the automatic engine mode

Will post a video soon.

Or you could just simply buy the CGP VSC1 which has been out for years...

I have this on my 435 - has a remote but also able to program OPEN/CLOSED to (1) of the programmable buttons on your rearview mirror

You can get it configured either way - OFF (default)=Factory Settings/ON=OPEN or OFF (default)=OPEN/ON=Factory Settings

Takes about 10min to install & doesn't need to be plugged in to your OBD Port like some others - PnP inline between car harness & valve right at the muffler. Unit mounts to existing muffler bracket bolt

...It might be less expensive and better value to buy Carly for BMW (Android or Apple iPhones) and their adapter.
