Yeah, I just did this Friday. These are the instructions I pulled and translated from German. I also found a factory ground bolt right next the the speaker cover, kind of behind the carpet.

There are two cables plugged in together where it points out the connector. You unplug those, it's the same lever style plug that's on the kitt, and then plug each end of the factory cable into the corresponding ends of the module cables. After that, secure them however you want (I used zip ties).

Then, find the grounding bolt to the right of the connector, and to the left of the speaker cover. Unscrew the bolt and secure the ground to it.

Next up is the 10A fuse, take it out, plug it into the modules fuse adapter, and plug that adapter into the slot that you pulled the 10A from.

Start it up, verify with the remote that it's working, and button her up.

So what's the verdict on how us here in the US can get it without overpaying? Maybe we can get Ronac to figure this one out and make one

Sent you a PM on how to bypass the US shipping restriction.

Thanks for the translation. But do you know what the buttons on the the remote do? Their are 2 separate remotes. One has lock and unlock and the other has numbers 1 to 3. When I toggle between 2 and 3 I hear a difference and number 1 does nothing. I thought this was suppose to keep the valve wide open all the time. When I switch between comfort and sport plus there is the usual difference in sound as comfort sounds like normal comfort. What settings on the remote do you use to keep the valve wide open upon starting the car which is in comfort mode by default. Thanks in advance for your advice.

Both remotes have 3 buttons, they do the same things but are labeled slightly different.

This should make it easier to visualize:

Very cool. Thank you!

badbenzz

Thank you so much

DriveAMG

Holy 💩!!! Wow is it loud when it’s on!!! So happy I was able to get this! It’s a huge difference even with sport plus... if you are on the ledge, get it. Install took exactly 5 min.

Hey guys, anybody knows if this module will fit a 2019 e450?

DriveAMG

I don’t think the e450 has one.

Tima I

ok, thank you.

Mind sending me a PM as well?

Interesting, a representative from Renntech said they do have it for e450. I am intrigued

DriveAMG

Renntech does list the e450 as using the same module. Not sure why. Up here e450 has a twin turbo v6 and no sport exhaust.

Has anyone tried this version from Active Sound? I think I would prefer to use the stock exhaust button rather than have a separate fob. Also it is much cheaper than Renntech. Is the only downside not having the valves open upon startup.

I don't know anyone who has tried it yet, but that is the gist of it, but the valves being opened on startup is the main reason a lot of folks buy it. It really does make a major difference. The other benefit to the remote controlled version, from ASR, is that they force the valves to never close, meaning you can use that feature to also keep you safe from the dreaded stuck valve flap issue and the limp mode it induces. But I would not pay the Renntech prices personally. It's more work to get the module direct from ASR, but you'll save a few hundred bucks.

Shoot me a PM if you'd like to know the steps to do that.

OC AMG

Thanks for the reply. Good to know about the stuck valve issue. For me I usually like the quieter start in the morning for my neighbor's sake but when I get down the street I open the valves for good. So I guess I would still be using the valves regardless of which system I go with. At least with ASR I would only need to do it once a day for the morning cold start.

Anyway, I sent you a PM. Thanks

For the same issue, I went with Cete's Active Valve Control. It opens the exhaust valves completely when you push the exhaust button on the car. No fob and no reduced sound at idle. The flaps are fully opened or closed. Cold starts now sound much better. https://www.active-sound.eu/en/merce...-valve-control

If you get it and want the installation guide, pm me.

Orcbolg

But you have to push the button, right? So it doesn't work on startup, just after the car is started? That's the main reason I decided against that one, as I wanted the car to roar to life, especially when out and about.

BucsFan

I push start and turn the drive mode to Individual as it's starting. It works just fine.

Anyone ordered this thing in the last month or two?

I ordered some sneakers from Europe and they've been stuck in US customs for weeks. vendor is saying there's a huge backup due to Covid-19. Debating whether to wait or just pay Renntech.

Orcbolg

Sounds annoying, and it's more expensive than the asr module, but at least there are options.

BucsFan

Since the car defaults to comfort mode, I always switch it anyway. It is annoying that AMG doesn't remember the dynamic select setting I was in when I turned the car off. But since it doesn't, changing from C to I is exactly what I do on every start up (even before installing this module), so this isn't any more annoying than what I did before. In fact, starting that engine and opening the exhaust valves is always great.

hey can you send me a PM on how to bypass the AST shipping restrictions? I live in Canada and the ASR rep told me they can’t ship it.
