Active Valve Control Module Review and Impressions.

[speeddemon69]

So after getting tired of dealing with the switching modes every time i start up the car, I started looking for an OEM like solution, enter Alex from europrice and Micheal from ASR. Both helped me quite well but after thinking it through i ended up paying a little more for the OEM solution. Alex@europrice placed the order from Germany and i got it really quick within 4-5 days.

Install was pretty straight forward and took me 45min to get done due to me not finding my trim tools and working in tight spaces and not wanting to break anything. I would post a DIY but it’s so easy that it’s not really needed as long as you follow the video or pdf. I will point out some of the difficult stuff in the video.

hopefully this helps and i was fighting a cold in the video so i seemed kinda "down" lol. for german video enable english subtitles to understand, I think one of them does not have that option.

I am in agreement with Speeddemon69...I have this AVC and can confirm the install is simple, straightforward and to me, well worth the price as well.

Thanks for the vid review...

What’s the purpose of this thing? Keep the valves open all the time?

Thats what I thought a majority of folks would want it for...

However, for me I wanted to be able to use the gear ratio in Sport mode (regardless of Dynamic vs Comfort) without opening the valves. So for instance, I am with the wife, and maybe I'd like a more spirited drive in Sport mode but dont want the RS3 growling all the time or picking up the kids at daycare/school and keeping it quiet on the pickup. I can flip the valves closed, use in Sport mode and enjoy the benefits of the that drive mode without being as obnoxious.

But yeah, for most, I'd assume it's a more functional piece to keep those valves open all the time....

speeddemon69, thanks for posting this! I can see that you can keep the valve fully open or fully closed by hitting the traction control button 2x. But how do you set it to operate in "normal" OE mode, where the valves would open/closed as if the module was never installed? Is it even possible to operate in OE mode?

XMetal. Per the AVC Website (which isnt very robust with instructions), I believe the OEM version is setting the Mode to AUTO. In Auto, the valves function as they would OEM.

I wonder if this would work on my stock, non performance exhaust...?

Remote way easier in everyway. IMHO.

The auto mode allows the car to control the valves in the manner it sees fit. You can either set the mode with the Drive Select button to go to full Automatic mode or using the Individual setting set the Engine Sound to Auto so you can then set other options in Drive Select as you see fit.

The drive select modes with the AVC installed are:

- Dynamic - Valves are Fully Open at All RPM
- Automatic - Standard Factory Valve Behavior
- Comfort - Valves Remain Closed until 5000rpm
- ESP Double Tap - Immediate Closing or Opening of Valves
- Startup - Valves Revert to Last Setting Used on Shutdown

The AVC makes the valves behave in a common sense manner so you have the ability to tune the exhaust sound easily. As mentioned below your post you can have the car in Sport and close the valves fully if you prefer or with a quick double tap of the ESP button open them up and when done with wanting the loudness to double tap the ESP and close the valves again.

You also get the added benefit of the mode you selected at shut-off to be on when you start the car again.

Oh and obviously no key additional fob that must be keep handy every time you want to change exhaust modes, Drive Select button and ESP button are all you need

Controller Package | S3, RS3 Exhaust Valve

It's really easy to install, works in a sensible manner, no additional parts as it's all factory button/MMI controlled.

If anyone has any questions don't hesitate to ask or PM/email: [email protected]

Cheers!

Yes, I use one on our S5 Sportback project with the factory exhaust since it's a daily driver. Use the Individual drive select mode to set everything dynamic except the suspension which is a tad harsh and it's the perfect amount of exhaust noise, good burble and pops/bangs on throttle let-off but not obnoxiously loud. Want to make it stealthy for a second or rolling in late I just tap the ESP button twice.

Cheers,

ASR controller has this as a switchable option on/off/oem, so you can operate thru MMI as per usual and not only in Auto. All to their own for these products just do your research and find one that suites you the best. Personally i like having an ancillary button for activation aside from double taping ESC, and has a service mode of disabling the unit all together.

If your car is equipped with auto start/stop the AVC unit can be disabled as well. You can always buy that separate OEM panel with the start/stop button like ASR sells too and wire it to make it work with the AVC module, even though it will make it even more expensive than it already is. Although my module is within easy access if i have a need to disconnect it, but with the MMI integration it makes it easy to choose how you want the valves to work for
each drive mode.

Your setup has way too many steps, almost a pita.
Guess I'm just too old and lazy.

Thanks but i'm happy with my decision and wouldn't go another way, AVC doesn't have a true OEM setting option just a modified MMI Auto setting and with ASR you can program it to start in whatever mode you desire. Service mode is simply holding down the button for 5 seconds rather than pulling apart side panels in the middle of winter depending on where you live, I'm getting old and don't like double tapping things unless im at the range with my firearms.Personally im not a fan of plastic units when there's a more robust housing available. Glad you like it just not my cup of tea.

ASR i was looking at is also plastic, i mean it goes in the interior lol don’t need a tank in my fuse box but i guess you prefer metal and thats cool. Also you got some slack to install the AVC somewhere where it’s easier to reach for the winter.

If you have the same start/stop button that ASR provides or live somewhere where it’s standard than you can also hold the button for 5 sec with the AVC unit to disable it.

I like the ASR too don’t get me wrong just i chose this one as i can control it in the MMI. I was going to get the ASR with the control panel but just wanted to try this one as not many had it. Trying to get the panel to

Speaking of fire arms, that’s something i prefer to be metal lol no glocks for me.

Once the AVC is installed it takes less than a second in 1 step, not even 2 steps, to change exhaust modes with the factory Drive Select button or the ESP button.

The point of the AVC is to make the valves behave in a more simplistic manner.

- Dynamic - Valves are Fully Open at All RPM
- Automatic - Standard Factory Valve Behavior
- Comfort - Valves Remain Closed until 5000rpm
- ESP Double Tap - Immediate Closing or Opening of Valves
- Startup - Valves Revert to Last Setting Used on Shutdown

The video made by the OP is to merely show of the AVC works with the MMI in your individual settings and there's zero need to even go into the MMI to change the valve behavior. Let's make this simple and I can demonstrate how many steps are needed to control the valves.

Changing the valves from closed to open or vice versa:

Step 1. Double tap ESP Button

Changing valve behavior with the Drive Select button:

Step 1. Tap Drive Select Button to Set to Desired Drive Select Mode

It couldn't actually be any easier. Literally one step and no need to use a separate key fob to have on hand, in a cup holder, rattling around, to lose or drop, to look down and find while driving, just use the buttons put in the car by Audi that are right in your view. Hopefully this helps with any confusion or misinformation, literally 1 step with a factory button for each function of the AVC.

Cheers!

[Optimus812]

Both units seem to have similar features except the AVC has integration with MMI. I went with ASR just because it was cheaper. Can't go wrong either way..

yes your correct ASR RX2 is a plastic one me being a tradesmen rather everything be metal so I grabbed the RX2 as i mentioned before just my preference. Im not here to bash the AVC unit im sure its a solid piece. Just as i always do is try to inform others on another product and it's up to them to decide which product suites them best as there are some differences between the two. Yes i agree with you on the firearms.


Yes Alex we get it on how the AVC unit works thanks. Technically there's 2 actions involved in activation on the ESC button so that would be a two step process. I'm pointing out the differences for others to make an informed decision not only one controller out there.

I am also just giving people correct information, repeatedly yes. Unfortunately it appears some people do not actually understand how the AVC unit works or they are purposely being daft or actually they are perhaps...

Hopefully my last post will make it 100% clear, despite repeated posts in multiple threads with incorrect information, that the AVC is completely hidden when installed, has no button on it and only takes 1 step to change exhaust valve settings with factory buttons. I hope I don't have to post yet again.

I understand your frustration I have no beef with the AVC or you that's not what im getting at. To bad people don't thoroughly read things.... but me being an anal bastard ESC activation technically is a two step process and two actions are required for modulation Cheers fella..... I'm pretty sure you should just copy and paste it on a word document and paste it when needed might save you some grief.

[Wkraus]

Do both pipes sound equal? I have my valves coded always open in dynamic with Custom Code tune and always both closed in comfort. But I still have less volume from the right side. Is this the same using this part? Thanks!

[TZilla]

More like one step with two actions (tap, tap)

LOL well played sir, glad some still have some humour on this forum. yah true depends how you look at it, as i said im anal about things.

Europrice is the official North American distributor for CETE items. You can find both the standard and programmable modules here:

A3, S3, RS3 8V | '17+ Electrical Parts

If you have any questions don't hesitate to let me know.

I just installed the Cete AVC in my RS5.
Main reason for me was to quickly switch from open to closed flaps and to have them closed when starting the car early in the morning, which would be nice and I only need it sometimes.

So far I’m happy with the quick switch by double pressing the ESC button and being able to have a nice sound even when in Comfort mode.

I parked in my garage in comfort with flaps closed but the next morning, the startup did not seem to be quieter than originally.
I also noticed that the exhaust burps when letting off the gas still only happen at about 2200 rpms, not below even with the flaps open.

Anyone else notice this too and would have any recommendations about a quieter startup in the morning?

Thanks
