I wish I do, the upgrade to HK I feel reasonable, but all the in stock X3 either don't have HK or it have HK plus way too many other package that I don't want.

So I end up got the one without HK.

Since you have the stock stereo, your only options are to install the Technic bypass harness or code ASD off. Read through the thread for details.

Thanks

Just order the harnes
Hope is not too difficult to install

Sorry if it's a silly question but does the M40d have ASD ?

The bypass harness is very easy to install. See Max Well's post near the top of page 5.

According to this post below, yes it does.

However.

It really ADDS to the car in the M40D. Absolutely love the subtle V8 rumble, really faint in Comfort and still subtle but more of it in Sport. Perfect, well done BMW! I'm guessing this thread exists a as the M40i version is trying a little too hard like the F8Xs. Damn.

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.

So the plug on the ADS amp cannot be unplug unless the ADS amp is removed?

The ASD module does not have to be removed to access the plug, it just makes it much easier to disconnect the plug. There is only one bolt holding the black bracket that the ASD module is attached to. Just remove that bolt and the bracket comes right off so you can rotate the ASD module to easily access the plug. This will all make sense once you are in there.

Sirs
I am a new owner of a X3 M40i, who hates the ASD / Fake noise on its basic stereo system. As I believe that just pulling the Fuses 218 and 203 does not work for my system, can you point me towards how to code the noise off please?

Thank you

Just got the harness today. Will see if I can find time to do it tomorrow.
Cross my finger I won't screw up.

winecracker · 04-16-2019, 11:03 PM

Today, I pulled the 218 fuse on my '19 X4 M40i and am so happy with the quiet. Takes nothing away from the driveability of the car......maybe even makes it better because I can hear my music much more clearly.

lo_cheng · 04-17-2019, 10:55 AM

Just done the harness install this morning between meetings. WOW. it was easy.
All I need is just remove the amp. No need to remove the ADS amp, don't even need screw driver.
There are enough room to just use finger to press the tab and remove the connector. Took 15min in total.

Done a test drive. the differ is DAY AND NIGHT!!
The car is MUCH more enjoyable without the fake sound.

Also, I notice music get much wider sound stage.

I really don't understand why BMW do this in the first place.
Or at least they just make it can be disable in iDrive. If it can be coded off, it can be done in iDrive.

The car is much more enjoyable now.

Thanks TX3M and Max Well!!!

I have a F26 X4 M40i with HK. The fuse panel diagram in the rear right side of the car only shows fuses up to 204. Is there another panel back there?

calintexas · 07-17-2019, 04:15 PM

What have people been doing when installing the Technic PNP ASD bypass harness (disconnecting the battery or not)? If the battery is being disconnected, what has to be done when it is re-connected? Are any settings lost, or does an anti-theft code have to be interred?

To your questions above - Disconnect battery? - No
Any settings lost? - Not that I am aware
Does anti-theft code have to be entered? - No

It was completely painless, though I did manage to cut by had somehow. Nothing serious : )

I did not disconnect the battery. I turned the engine off, left the car alone for a few minutes (until the screen above the head unit turned off), then opened the trunk and proceeded with the cover panel and amp removal. It was all completely straightforward. I have not experienced any adverse consequences from not disconnecting the battery.

2nd that. You absolutely do not need to disconnect the battery. Also, you can manually turn the vehicle off with a long press of the volume button.

I pulled the 218 fuse on my HK X3 M40i PPF car a couple of days ago. I have to say I was shocked at how much fake exhaust noise is pumped through the speakers. The car is so quiet now its unbelievable.

I'll be making the mod to the rear box next to see what this is like and then maybe BM3

calintexas · 07-21-2019, 02:47 PM

DD694, gugin. TX3M; Thanks for the responses to my question. I couldn't find that anyone had said what they did previously. Not worrying about the battery cables makes the job a lot simpler.

SteveX3M40i · 07-22-2019, 07:34 AM

Hi,
Just got our M40i back from the dealer (after having some bodywork repairs)
It sounded louder than before it went in - just discovered that somebody had put a new fuse 218 in!
Just going to remove it now - to make things a bit quieter in the cabin.
Cheers
Steve
