Active sound module
I am a quite new owner of the C63S and I love it. But, I doesn't have the sound I expect from an AMG. Even though my car is equipped with the performance exhaust it doesn't give me enough AMG feeling. Hence, I started researching and found this video:
It basically tells you the exact version of software for both the engine itself, and the gearbox. Great I thought!
But, after extensive calling to authorised dealerships around Sweden (where I live and the car is registered) they told me this software version cannot be fitted in my car due to EU regulations & the fact that they can't "choose which software that goes in my car and gearbox" and/or "retro-fit old software" into it. Major bummer.
After this, I went on to do research with different non-Mercedes-authorised tuning companies. No luck here either.
I finally then found the Active Valve Control stuff, that according to this video (already posted above, I know) from the seller CAN MAKE IT SOUND BETTER:
I've emailed the guys now, expecting an email back Tuesday next week or I'm giving them a call. I really, really hope this will give me what I want. Is there anyone on this thread successfully mounted a mod that ensures 100% open valves on all RPM's?
Thanks in advance guys!

The adapter would then allow us to put the unit in the trunk, and only have that function?
And by the way, if I buy it and it doesn't come with English instructions I'd be more than happy to make a short video.

install is very easy,,,complete plug and play.
I know you guys are waiting for GB but a lot of time that takes a few weeks or more to go through. I think the ASR is worth the money I would just buy it outright.
here is video I used to help install

My ASR is mounted in the trunk.
I cannot buy a piggy-back unit that goes in the engine room as I'd be in trouble when I do my yearly inspection. At least that's a no-go for me in Sweden, and I'm guessing it's the same for any and all EU citizens.
That only leaves the Active Valve Control option for me.

==================
Hello,
I am interested in your product:
https://dbautoveredelung.de/epages/1...roducts/AKSUEM
I have a C205 C63s Coupe (2017) and would like to know where is the install location? (inside trunk?)
Also, is it 100% plug and play or does it need to be hardwired into the Canbus?
Would you be so kind to sent me your installation instructions for this unit?
Thank you very much,
==================
Hello
The flap control is connected directly to the exhaust engine. This is not connected in the trunk.
Disconnect the cable from the exhaust engine and plug in the flap control
Best regards
Mit freundlichen Grüßen
How does it sound with this module and is it worth the cost?
thanks in advance

After a lot of back and forth, I'm placing my order today with Active-Sound. I don't want a piggyback in the engine room in a premium car. It's expensive, but hopefully it'll be worth it. Review in this thread can be expected from me!
