Technically, it doesn't ever amplify engine noise -- ASD augments the engine sound with artificially generated harmonic content to "fill in" the spectrum in a way that the engineers wanted.

It never stops unless you have it disabled.

What's the best method to remove ASD? Code it out or use the adapter harness?

Happy with the harness. I only hear real sounds from my M.

The best bet is the harness if you want get the most improvement -- the ASD module is a power amp in series with the stereo amplifier which distorts all audio. If you don't want to remove the trunk liner and/or don't like DIY work then coding is lower effort but doesn't improve audio performance just eliminates ASD.

I'd recommend the harness.

Guys anyone wants to do a groupbuy and get them shipped to Europe?

I definitely need this for my car. When the radio is off, I hear a slight noise on the speakers and I think - after reading all here - it might well be the ASD playing up.

Anyone here who noticed it?

Holy crap!

He must have run out of connectors. That sucks for everyone still living with the ridiculously obnoxious ASD in these cars. Faced with a weeks long wait I'd probably code to tie me over if I didn't already have the harness.

Yup that is the one! The guy discussing the upgrades to the HK system also mentioned it is there. Definitely going for the cable soon, and then in the winter upgrade the speaker system.

Bypassed the ASD. I consider it a definite provement. In routine driving the ASD was too much. The engine still sounds great. I have nothing against artificial sound in theory, but it started to sound like white noise and was giving me a headache. The instructions provided are totally accurate. I try to avoid do it your self projects but found this one necessary. I was able to install the harness without too much trouble.

Pointers I can provide: 1. When removing the grey casing from the wiring in the car withe the pic/awl remember there are two separate pieces inside. First release one side and then the other. 2. When plugging in the harness to the ASD initially the black lever should be all the way up. Once it is plugged in it will slide down a bit and then you can slide it all the way down and lock it in place.

Thanks for the info. It is a great car and now even better.

Anyone here who had his ASD bypass harness shipped to Europe? I tried to order it at Technic PNP, but they do not allow shipments to Europe.

Ask a friendly member to forward it for you, I'm sure you'll have no problems finding one and it won't cost much w/ USPS

Getting mine sent to my hotel when i'm next in the USA.

why not just code it off for free instead of buying a bypass harness?

Apparently the quality of your stereo system is degraded somewhat with just coding method. If you want the best sound possible, you want to remove it.

I thougt that in sport and sport + the exhaust of the M2 also got louder (flaps inside) then in comfort. Is this only ASD that makes the sound level change between comfort, sport, sport +?

I thought the flap only opens under hard acceleration even in Sport/Sport+? I could be wrong. I disconnected the valve on mine to hold it open.
