Keep The BMW G20 Exhaust Valve Always Open | Free Mod | 2019 BMW 330i | 2020 M340i | 3 Series
HTML-код
- Опубликовано: 20 окт 2024
- I have been wanting to do this mod for the past year, finally I did it and documented the process. It takes a few minutes to figure out how to pull it but it is fairly easy. Make sure you put the car in sport mode and let it heat up, once you hear the valve make the sound that it has opened and the car is idling quietly, it should be ready. You can then pull the wire from the controller to keep the valve open at all times. This increases the startup sound greatly and allows for more backfires at low RPMs. You can do this on any BMW G20 Series from the 2019 330i, 2020 330i, 2020 M340i and most likely the 2021 models too once they drop. Keeping this open is the easiest, cheapest, free mod that you can do on a BMW G Series, 3-Series.

I think you also need to seal the female plug.
The packing tape car mod 😱
Does doing this have any sort of negative side effect? Does it provide any benefits? Sorry I dont rly understand what this does
Pretty sure there are no negatives. Deosnt void warranty either cuz its easily removable and manufacture deosnt care. This will only make the car sound better. The valve opens in sport mode(basically a flap to make it louder) with this it will stay fully open. From the manufacturer the valves open more in sport but close slightly at lower rpms and this just keeps it open
@@Emiliotattedmethank yu bruh yu a life love ong 😂😂😂
Can you throw in a small video with you driving in different modes when it is like this? Just to see how it sounds
Inside & outside the car? I’d like to get that done soon
Yeah ! Both inside and out, but mostly I think you can't hear it much on the inside. Can't wait to try it out
TheLostDigit yes please I would love to here it
Dope tip bro, can we get a better exhaust clip?
just remove the connection rod and put it back upside down with tention so the engine part moves freely and the valve is locked in open position
By plugging the male plug back upside down into female connector, will it get short circuit?
hey just wondering i just did this on my car and is it safe to do this or will water or whatever damage anything?
If youre in europe, this will throw an engine light. We have PPFs (petrol particulate filters) here and to do a regen the valve needs to be closed. USA is all good as you dont have PPFs.
gfusion that’s really good to know. Thanks! Is that why some EU models don’t pop or sound the same?
No i had 3 german G20. none of them had check engine light after mod.
I've done this on a uk 2022 M340i. No CEL. Much better sound
Hi great vid, definitely giving this hack a go. Do you need to keep the engine running in sports mode when you disconnect?
After disconnect it remains open in all modes.
Yeah, i did it in the 340i. Kept in sport plus, disconnected clip, then inverted the clip and pushed it back in (more secure this way imo) valve stays open
@@turdseyeview4763 thank you bro so excited to try this with my x5 50i
@@sammyshadi7621 sweet car dude, gonna sound soooo beastly :D
@@turdseyeview4763 inverted as in plugged it in upside down?
Oh snap it worked! any side effects or none to worry about ?
any side effects you noticed??
Im interested too
No real issues, they are closed to warm up the engine faster, but take a look at the E92 M3 Exhaust, no valves at all. One pipe is open at all times anyways all this does is add more sound.
Just did it on 19 330i, which has nice stock burbles, and it sounds so much nicer. I don’t know why the valves close when in drive, as I noticed that they open in sport mode when in park, neutral, or reverse, but close as soon as I put the car into drive.
I would assume that it would be better for them to stay open, as the car is able to exhaust easier as it has both the left and right pipes to let the gasses out of now.
If you’re debating on doing it, I’d say why not, you can always reconnect she harness.
have you noticed any issues with the car since doing it?
So the check engine light wont turn on if you unplug it?
this is an amazing tip but has the car turn on a check engine light ?
No it didn’t get one
Does the car has to be on or off ?
am new to this can some explain why your doing this whats the purpose behind this and will this affect the car in any way
Thanks for the life hack!
Unplugging that valve barley did anything and it also didn’t sound as loud in the cabin with sport mode on.
Very Cool! Do you know if there is a way to code in the pops/burbles in the EU 330i? They dont come with pops cuz of regulations, so what to do?
Keep up the good work man :)
An ECU tune would do it, but that’s not something I’d do to a new car.
Steven Shilish have you found a way to get the pops and burbles back? I’ve driven an EU 330i test car who did have the pops, but my own EU 330i unfortunately doesn’t have those ...
@@NS222 No, have not got my car yet but I heard that only US versions get them, which is really sad for us in the EU..
Steven Shilish congratulations with your new car! It’s a pity yes, Maybe I should look into exhaust modification to make my car a bit more louder ...
Mine is a UK car and it does pop
the tape is going to melt and you will not be able to take it off
I tried many times to unclip it but I couldn’t. Can you help?
Need help unclipping too
Is this also possible with the 330e ?
Code it with bimmercode and you will have the option to open and close by idrive settings
Is keeping the valve open better for the car or not?
Did you drive the car in sports mode to open the valve? Mine is the X6 and told that its valve only opens in high speed…
Hey buddy. I just ordered a 330 without m performance package. I just wonder if they sound the same.
I have mines w m performance and when I put it on sport it’s amazing. I think there is a clear difference but you can straight pipe your car.
aywa l sayedd. Waiting for your next upload (upload more wla)
Is this valve system in only M versions? Sportline or luxury line have that?
Stupid question, but do you only need to do this for one side? I'm about to try this tomorrow on my M Sport. Just coded in sport plus today which was a nice addition as well! Thanks!
joe morgan how did you code sport plus? Is that new on BimmerCode? The 330 has only one valve yes.
Super easy. I bought an obd reader for $60 on Amazon and took me five minutes.
joe morgan thanks, I’ll try it out. I have a few things coded but this wasn’t available a few months ago!
@@binarycars yeah it was recently added and it's a nice to have!
joe morgan man... it said my adapter was not supported for the body domain controller, I have the V Gate WiFi. Which one did you use that supported this controller?
You can also start on Sport mode and avoid all that. If you leave like that, protect the contacts on the valve as well!
fegari g sport doesn’t stay open when in idle and drive, this sounds the best overall. I might go back to normal though, we’ll see.
@@binarycars
What u mean it doesn’t stay open when in Drive mode?
@@MrSilk07the valves constantly close and open depending on speed and rpm’s. So even if it does open in sport while starting as soon as you start to reach road speeds valve may close fully or partially depending on a lot of factors.
At least in my M340i in Sport plus: In idle, the flaps are open, as soon as you start driving, the flaps close and stay closed until 80 km/h. They only open up under load in the higher RPMs when everything is stock.
Any one knows the part number from the connector ? The one that you are covering ? I need to replace it , coz the connectors got bad , seal is brokent... :((
Do you really think this primitive tape will protect the plug from moisture ???
Secondly, what will happen to the unprotected pins in the black box, mounted to the exhaust when they become wet ???
Peter Hrd corrosion most likely, but I’m just protecting what’s connected to the cars electronics. The valve pins are now not connected to anything.
Well wouldn’t it close if you turn the engine off?
Hey do you think this would work on a 2022 430i, I just got my muffler removed and noticed that the there's a valve. It doesn't blow out from that one tip (obviously cause of the valve), so do you think i could do this too and make the car a bit louder?
Probably, it should help it breathe better
Did you get it to work? My car wont open the valve if its just idling at sport mode
Hello, thank for the video
Do you have any update on this? How is it going so far? Have you had any issues? Does it sound amazing when you drive?
All good so far! Sounds great
TheLostDigit, I’m going to try this soon hopefully. I’m scared since my car is a lease, I don’t want to cause any issues
Len Espi lol mine too 😆😆 it’s easy to push back in worst case
@@binarycars Hey after 2 years have you got any issues?
I don’t have the car anymore sorry!
Have you had any problems with this? I’m worried about my car going into limp mode
This will probably give you an error message but it won't trigger limp mode.
Do you know if this will void warranty?
If I’m going this the engine light come up ?
Got a 2021 m340i and I can’t seem to remove the clip by any means bruh
so its just basiclly sports mode all the time or does it do anything else?
It may make your mileage worse too 😀
Hello can you please tell me how you opened the valve? After 30 seconds i dont understand that part how you opened it?
When the engine is warm and it’s in sport mode, it opens by itself
It makes the car backfire? How does an exhaust valve opening cause excess fuel to be burnt in the exhaust...... it makes no sense. I’m pretty sure it’s just reverberation from ignition retardation above certain revs like most modern sports cars.
NL3044 it doesn’t make it backfire, it allows for more air to exit
Why you didn't do the same thing on m340i 2021 to have more pops ?
I did, didn’t help
@@binarycars so this method won't help with getting more pops with the 21'?
@@seanw9425more burble but no more pops. Pops are really a dme/ecu thing as they require overrun (fuel continuing to be injected into the cylinder even with no throttle. No throttle = no oxygen. No oxygen = no fire. No fire = fuel is dumped into the exhaust.) The pop is the unburnt fuel igniting when it hits the hot exhaust
The diesel ones won't do that right?
You used scotch tape??
any tips to unpluging it becaue it is very hard to do it
There’s a clip you have to push as you pull
on my430i you can select the sport exhaust sound as permanent in the cars settings is this the same/
Wrong method. You just need to do the coding to control the valve from the head unit
beast
Do you get check engine lights?
Does this cause a check engine light?
No but it will put your car in that limo mode telling you to call emergency services. Just code it out.
same thing on the 320i ?
I have a question so if i do this i won't get any codes or lights in the dash right?
I'm wondering the same thing
@@Bmwfanboy16 u wont. tested on my G20 LCI.
This is worked on g22 too🎉
It works, thanks for the life hack
With 330e doesnt work.
Hey my check engine just came on with code “ exhaust valve plausibility timing” would this be one of the problems??
Does it throw a check engine light? If not any obd2 errors?
Johnny Meza nothing at all. Done the same to my car and no problems
@@germancollection_br hey man still no problems?
@@sammyshadi7621 Nothing. I have sold the car in February, drove over 7000 Miles (11000 Km) and no issues at all. When I sold it just plugged the cable back in and it worked again just fine
Do you have the engine light on after unpluging in the dash?
No
I’m confused though why you need this......... in sport plus mode the valve is always open anyway? So what is the need?
startup sound
can i do this on a 2020 330i? or did they remove the burbles on the 2020 model
Did you ever figure it out? What have you done so far in terms of an exhaust system?
@@JustinAlston2 which year do you have
@@axl6670 @2020
Wait, so the valves automatically open after 30 seconds idle??? Please reply asap if you can!!
only in sport mode
@@Nosity Test drove an M340 and was wondering why it was so quiet very good to know that valves open up on their own after just a couple seconds!
I done the the same. Hyundai i30N. And lose time when i change a gear to another, when i run. So its has disadvantages,
does this work for the 320d?
순정배기 항시 열어놓는 방법있나요? 배기 듣고 싶을때마다 스포츠모드 누르는거 귀찮네요
Doese it show any dtc on idrive?
Why is the exhaust valve present in the first place?
Most likely noise control, it could also be used for other efficiency reasons. If you’re always driving sport it probably doesn’t matter much and will start up louder when open
I just coded it into iDrive so I have an option to open and close them as I want
Do you have an howto or cheat sheet?
@@Venigo I watched a video on RUclips but I can't seem to find it right now. It a little more advanced of a code but the steps are out there
@@buda7326 ive checked it in idrive. But for the 330e, this option is already available :)
@@Venigo What? We can force to open the valves all the time in the 330e? I will do mine tomorrow I think but I’m not sure yet
Did you have to lift the car to get underneath it
No, I get on my back
Can you do an update? Any codes? I just did mine but want to know
Updating usually wipes the coding
Wtf! I unplugged mine and it closed the valves, why?
Lmaoo
once the valve opens, you can turn the car off and it remains open?
Yes, after unplugging it
Thank you! Will it throw an a CEL?
Amessad so far no
It’s been nine months is there any warning lights
Does bmw 330i base model have that too
It should yes
For some reason mine closes
Just a quick note to anyone who tries to do this on the g20 330e, it’s not going to work 🙁
What’s the difference?
Will Raven the car is calibrated differently don’t there’s no burbles and the valve is closed for much longer at lower RPM to reduce noise whilst driving in cities. I bet with a remap this could be fixed or just physically disconnecting the valve from the solenoid in the exhaust.
londonas2 The valves in my 330e are half open now and connector is unplugged. Was like that when I bought it at BMW!!!!🤷🏼♂️ Going to try get valve completely open snd then unplug
Will Raven ooh lucky man, I’ve drove mine for about 3k Miles now and every time I check whether the valve is open, it’s shut unfortunately. I’ve read a lot of forums online as well and it seems people are having the same issue as well. Also, there seems to be a difference between 2019 models and 2020 models for some reason so maybe calibration changed at that point 🤷♂️
londonas2 I have a 2020 model, I guess since I bought it nee this year in march. I went to a garage to check the connector and he told me it is already unplugged. Strange you should get a new car in OEM condition normally. Maybe they where experiencing at BMW I don’t know. Sound is still not amazing with a 45 degree open valve but I don’t know how it sounds with connector plugged in
Does it show up on the car as an error etc??
Didn’t for me
100% doing this
Tape. Packing tape...smh
Those it throw a check engine light
Haven’t had one yet, maybe the G20 doesn’t care like the F30?
Is this possible on a 320i? I considering buying one but it sounds boring now.
And what is the difference with the 330i since they have the same engine?
Vyper they are tuned very differently but seem to have minor physical differences. 181hp vs 255hp.
@@binarycars So its just a software tune? Then I could chiptune a 320i to a 330i?
Vyper not necessarily, the engines are both b48 but there may be differences as their product codes differ, you’d have to check for what people have been able to do safely without hurting the engine
I believe 330 has twin turbos
TheDaddyredd twin scrolls but single turbo
Wat exact color is this called
Mineral grey metallic
Can you do this with a 2021 330i!?
I don’t see why not, as long as the valve opens when in sport mode you can unplug it
Do NOT do this. It will put your car in limp mode after some time. Just code it to stay open.
Did it for two years without issue
Hahaha, go change the sport exhaust better
318i ?
330i
@@binarycars y’a pas sur la 318i ça ?
Hi,
do you think the 530e G30 also has these valves?
Yes it does, my 2022 530e has them on the right side
