no limp mode no loss in power, just extra noise.I did this to my last car which was an RS3 and again had zero issues. It will throw a code because it is unplugged but does not cause any issues.
Test it out, it will take you 5 minutes to do and whats the worse that can happen, you get a code and you plug them back in.
Just following up on this thread. Has anyone installed and tested the ASR module? For me, it seems too good to be true and I can’t quite hear the differences in the video provided by the manufacturer.

Yes.
Several users including myself have purchased and use the product and I have yet to hear of someone who wasn’t happy with the purchase.
Yes it works exactly as it says on a facelift providing you order the correct one.
it’s a great little gadget mostly allowing you run the car as loud as the stock performance exhaust will go all the time, especially in comfort mode. I just leave it on all the time by default unless it’s after midnight.
what I would say is although it works well it doesn’t make a huge difference to volume even low down in the rpm, quite simply because the facelift is muted outside anyway.
for me it’s a tool to keep the exhaust on the loudest it will go all the time when flicking from sports plus back to comfort whereas otherwise by default the car would go into quiet and I find it annoying to hit the exhaust button every time I’m in comfort mode. In sports + or race I feel I’m trying to convince myself it makes a huge difference in overall volume.
defo a good purchase for the price.
Not sure if everyone is clear on this yet, but it has been stated multiple times.
Whether you are in comfort, sport, sport+, race, PE on, or PE off, the flaps are usually not completely open.
When you reach a certain RPM, they open (although I’m not sure if it is just partially or completely).
What the ASR module and similar products do, is they connect to the valves directly from a fuse in the trunk, and they bypass this logic.
It allows you to use the handheld controller to completely open or close the valves.
Regardless of which drive mode you like, there 1000% is an audible difference between 0-about 3000 RPM.
Above 3000 or so, one would be correct in saying there is no difference, because I believe that is around where the valves would normally open up without the ASR.
The times when I hear the difference most are driving around parking lots and when I start moving from a stop. And that difference is undeniable, I’m sure anyone with a facelift would agree that at low speeds the car is nearly silent.
I can 100% state with absolute certainty that in a facelift model (May 2019 build) it works, and low down it keeps the valves open all the time (again it does exactly what it says on the tin) but I dispute how audible this actually is with the windows open from the position of a driver. I will make a video on the next fine day I can but I doubt anyone will be able to tell on a video on a 2019 so it’s largely pointless.
I’d say it’s maybe 5-10% louder at low rpm (1-3000) regardless of drive mode but obviously since sport plus actively turns the exhaust on it makes less of a difference there. Therefore most noticeable in comfort mode as the flaps are never fully open even in ‘exhaust on’ mode.
From what I’ve heard the valves are already a lot more open all the time with the facelift compared to a pre facelift with the exhaust on and so the ASR module makes less of a difference relatively speaking in the new car compared to the previous one.
anyone buying this to keep valves open all the time will love it but anyone looking to make the car much louder will be disappointed I think.
And yeah facelift is disappointingly silent with exhaust off.
👍

I'm SUPER HAPPY with the end result after installing the Active Valve Control from Active-Sound.eu yesterday. Now I finally hear the potential in this car, it has a deep tone and is much louder during low RPMs. I can no longer cruise unnoticed on the streets apparently (if flaps are open). Another thing I need to mention is also how quiet and comfortable the car is when the flaps are 100% closed. Videos are coming, just need a tool that lets me blur my license plate. Any advise on software I should use?
Yes, I paid a higher price for my unit. Yes, I needed to "hardwire" and cut cables in my trunk - but it's worth it with the security features this module has. Even if my flaps are closed 100%, they will be forced open at high RPMs. The installation took about 20 mins.
I'm still waiting for my MB dealer to get back to me in order to get the latest software to get some loud crackles. I can't wait.
Please make sure the unit you are mounting has the same features, in order to not cause damage if you end up driving hard with the flaps closed.
EDIT: The perks (and reason it's more expensive than competitors) of the Active Sound version is that the exhaust button in my car still works, and it has the security feature mentioned above.
Could you kindly describe how you used the included splicers to connect the CAN BUS wires?
Hi . Today I installed the asr module and I don't know if I did the cable installation well. I took a photo because I wasn't sure if I did it right. If anyone can tell me if it's right or wrong, I appreciate it

Looks as it should. The connectors are male/female and you cant really accidentally swap them. Also, no other connector in that areas of the same type. I just wrapped them and made sure the module and cables don't rattle or can move.
well, it seems fine. It works very well . What I did not do is disconnect the battery from the power . I have read and this is badly done I know. But it seems that nothing happens or I hope it does not affect. I have not yet gone out with the vehicle.

no worries, nobody disconnects the battery for that. Not sure if its even hot when car is off...don't think so.
okay . not the car had 4 days without starting so good. I was a little worried but thanks for confirming. I try to upload a video but it seems complicated )
So I current have the ASR installed on the 2017 C63S Coupe with an Eisenmann Exhaust. My 2020 arrived early next week. Will my module work with my 2020 or so I have to buy a new one? The exhaust should fit without a problem.

Just caught wind of this thread today and went to check out ASR. The module is $627 now!! Is anyone selling theirs for a more reasonable price?
I see a $274 USD price on ASR's website. However, I was curious about shipped price to US and got an error "No shipping service available for this delivery address!". So it seems perhaps they've stopped shipping to the US.
I'm considering the Renntech instead. It is much more expensive, but I do prefer a name I know (and that my MB dealer sells and installs) vs the random ASR company.

ASR and Renntech is the same. As often pointed out - Renntech has the sole distributor agreement with them for the US - same module but ASR is not allowed to sell direct in US and instead Rentech sells them as EVM.

Ah, perhaps I did see that elsewhere on the forum. So that explains the error message when I tried to order directly from ASR and ship to the US. I just finished reading through this entire thread and know a ton of people got the ASR unit. None of those were US people?

I think there was a time when ASR sold them anyway to US customers but last time I talked to them they got into trouble and had to stop (I assume Renntech was not happy). If you have someone somewhere else like Canada or EU they can order for you .... or just fork over the extra dollars. Sometimes you can also find them on market place or maybe e-bay.

Got it, thanks. My dealer has the Renntech branded one in stock, but they only sell parts if they do the install and they want $175 (1 hour labor) for the install...

yeah....takes all but 5 minutes (and the longest part is getting the trunk floor liner and netting out of the way). Renntech also quoted me an hour.... you can buy from Renntech direct online and save the $175.
