Did anyone get any fault codes or error notifications when pulling any of the fuses?

What is the concern about the voice recognition?

: I have the same question...

Maybe someone thought that when ASD is off, the car computer may not recognize us any more since our voice is now less throaty?

Seems fine; I tested some commands and they worked as expected.

I'm thrilled to lose the piped-in noise. The actual mechanical voice is sufficient for me. As others have said, the stereo doesn't have to compete, and sounds better as a bonus.

Back in post #74, Supersebbo said:
"Looking at the diagrams, the only remaining concern I have it that if you pull the fuse on the HK system it may leave the ASD analogue inputs to the HK amp floating, which might cause buzz/interference. That said, fuse pulling will be better than disconnecting the cable because the ASD module will at least stay connected to the common vehicle ground voltage.

Installed the ASD harness on our HK system yesterday - a definite improvement for us even without music. Would also agree with others' comments about music sounding much better as well.

For those still unsure about installation (and who don't wish to code it off or remove the fuse), here are additional step-by-step photos to complement TX3M's excellent initial images. These show the slot the ASD side tab slides in- and out- of on the blind side not visible in most pictures, the 8mm wrench size needed for the ASD nut, how a towel made supporting the heavier amp easier, use of a socket to hold the 8mm nut when replacing (I kept dropping it), and a tie to hold the plug union tight against the frame. Thanks again for the thread, TX3M.

Thanks to the many great tips in this thread, I pulled fuse 218 and disconnected the ASD on my 2018 m40i (HK option). No issues have cropped up since doing so on 2/2/19. Pulling the fuse made a substantial difference in cabin sound level - it's much quieter in the cabin with ASD disconnected...almost too quiet. So far, I've been driving in Comfort mode, I haven't sampled the sound level in Sport modes. I wish the ASD level was a setting where the level could be set from zero to max. There are times when I might enjoy the faux engine sounds, but if it's either on or off, I think I'll likely stay with ASD off.

So just to be clear as I have not received my car yet I did order an M40I with the HK stereo. I have nothing to code with but plan to in the future. I did not like the fake engine sound on the road test.

So does the jumper accomplish the same thing as pulling the fuse or does the jumper kill the fake sound and improve the sound quality of the radio system?

I am not opposed to buying the jumper but if it is the same as pulling the fuse then why buy the jumper?

Thank you,

Brian

Hi Brian.
For cars equipped with the HK system - you just need to remove the fuse.
For cars equipped with standard audio system - you need the adaptor harness.

I pulled the fuse as well and would agree that the cabin is pretty quiet now. I did however also pull the fuse to keep both exhausts open at all times so that did help bring some of the real noise back into the cabin as does driving in sport mode.

Which fuse do you pull to to keep both exhausts open at all times? Does it affect anything else?

Fuse 203 is for the exhaust flap. Take a look at this thread:

There is a difference between pulling the fuse and using the bypass harness (according to the posts in this thread):
- If you pull the fuse, it might result in an ASD fault code (we're waiting for someone who has pulled the fuse to report back after their next trip to the dealer), which may prevent the dealer from being able to perform software updates. You might have to put the fuse back in before visiting the dealer to avoid any issues (not a big deal, but worth mentioning)
- If you install the bypass harness: According to the Technic website, "The "ASD module is still operational and visible to the dealer computer so all OEM car software updates can be performed without ASD errors".

Someone please correct me if I'm wrong.

I have the ASD module disconnected on my HK equipped vehicle which has worked just fine. For convenience, I am purchasing the bypass harness just so I don't have to re-connect the ASD module (or put a fuse back in) every time I go to the dealer.

That is what I was trying to understand. If pulling the fuse causes a fault code and the jumper harness does not then the jumper may make more sense in the long run?

[chicagofan00]

I pulled the fuse and have not gotten any fault codes indicated on the dash or in iDrive. If there has been a fault code generated it was a silent one.

Hi,
The point that I was making was more that if you don’t have the HK system - you must use the harness - as the fuse option will not work.
With the HK system - the simplest and cheapest option is to remove a fuse that takes a few seconds.
I can live with putting the fuse for this and the exhaust flap back, before every service - if required.
I am going to leave them out for my first service, out of interest - and am going to discuss this with the service manager to see firstly whether their diagnostic systems will pick up any faults and if so - whether this will cause any problems.
I will tell him that the fuses are in the glovebox and that they are welcome to replace them, if required.
Once I have all the correct information from BMW service - I can then make an informed judgement as whether to buy bypass harnesses, live with fuse in and out each service or just remove and forget!
Cheers
Steve

Thanks Steve, please let us know how your next visit with the dealer goes!

Hi Steve, do you need to turn the car off before pulling this fuse? Or any another specific steps other than a simple pull? Many thanks. V

Hi,
I did - but apparently you don’t need to.
The fuse box is hidden behind a cloth cover.
You need to remove two plastic clips on the right hand edge of the cover to reveal the fuse box..
The centre pin of the clips needs to be pulled out - before pulling the whole thing out of the hole in the bodywork. This is the most fiddly part of the job - as well as replacing the clips - after you have removed the fuse.
There is a fuse puller clipped to the front of the fuse box.

Don’t do what I did - I took out the two clips, revealed the fuse box, unclipped the fuse puller, removed the fuse, replaced the cloth cover and re-fitted clips.
Then discovered that I had the fuse and fuse puller in my hand!
I could not be bothered to remove and refit cloth, to put puller back on the fuse box - so I just put the fuse and puller in the glovebox!
Cheers
Steve
