F80 Active Sound Design (ASD) now switched off thankfully

Post by adie » 29 Jan 2016, 05:24

After coming from an F30 335i the interior cabin noise in my M3 became very annoying and fake due to the synthesized engine sound. I didn't mind the noise at first on B roads / country lanes but on the motorway it was far too intrusive and unnecessary. The ASD module is located in the boot and plugs into the HK amplifier so i've now pulled the plug on it. I can now enjoy the natural engine and exhaust noises... which are great :)

I can't imagine what the engineers at BMW were thinking of when they thought that ASD would be a good idea... reminds me of something we would have done in the 70's to our MKII Ford Escorts!

With all the functions on the i-Drive why on earth didn't they provide an option to turn it off?... or at least adjust the volume.

Anyone else turned their ASD off... or perhaps some like it?

Does seem odd to to include any function to reduce or eliminate ASD - although in my brief forays with equipped cars I never felt the need (but didn't do long motorway drives). Apparently you can simply remove the connector from the unit to stop it.............which I assume(and it's only an assumption!) means it'd be easyenough to install a concealed switch in the cabin?

Yes, i removed the connector, a bit fiddly to reach but the result justified the scratched hands.

I had the same thought about installing a switch but it's a multi-connector with about a dozen wires coming out of it so not straight forward unless anyone has identified which wire/wires could be routed to a switch.

My only concern at this is point is whether i should re-connect it when the car goes in for it's service, presumably any software update will check the existence of the module... but hopefully i may be wrong on this... do you know a friendly technician at Elms Bedford you could ask the next time you visit the dealership?

I've never met a Tech - they're always behind a perspex screen!
However......

Excellent!... thanks Neal, i'll post my question there. Didn't realise that Elms had Talking Techs!

I'll post their response on the forum.
