Unplugged exhaust valve issue.

[Micronaught]

So playing around after I installed my Milltek secondary cat bypass pipes , I again unplugged my two exhaust valves , sounds great but I found the next morning after a drive to work the unplugged doors had closed. Now I wonder if they need a powered signal to maintain an open condition as I am 100% sure i unplugged them in the "open"condition, both . Anyone have anything similar?

Heard that trick doesn't work on the facelift RS3 like it did on the pre facelift RS3/S3/R.

I believe the valves need an electric signal to remain in the open position. Simply unplugging them will default the valves in the closed position. Somebody correct me if I’m wrong.

Question, any codes from unplugging the valves?

Seems likely , I guess I’ll have to get one of those hokey remote control fobs all the VW guys love. 😜

Can you use the rear foglight power? Then you'd have a switch too...

Unplugging the valves on te Rs3 makes power loss. I have seen a tuner doing a stock software run before tuning and loosing around 20 crank hp. When they noticed the owner had unplugged the valves they repluged them and did another dyno run with 20hp more.

I tried it for about two weeks, they stayed open the whole time (maybe it takes longer?). I just plugged them back in today as we are expecting lots of rain here in VA and don't trust the open plugs getting wet even while covered in tape. The car sounded good but when you're not moving you really notice a deep bass frequency that's not pleasant until you start moving again. As far as power loss goes it's unnoticeable, still fast enough.

Interesting point. I did notice power loss when I unplugged mine as well. But this was mainly at city driving speeds.

On the pfl rs3, the valves switch to full open at 3800rpm.

ASR has a flap controller for this, MTM also i believe carry one as well. ASR controller opens and closes the flaps 100% and also gives you the option of going back to OEM function. There's also a dash piece option were you can use a button on the multiswitch button panel for activation if you don't want to use a remote. I've had this controller on around a month, no issues with power loss as it seems to be a bit smoother. Might be a solution for some of you looking at this mod.

Do you have links to the ASR and MTM controllers? Thanks.

I'd email Michael, he's the owner and speaks english. Replies are quick and he can answer any questions in detail for you. There's a you tube vid that shows operation of dash but its in german and will need to translate. The last mode start is a great option no more switching through the MMI. Everything about the sound is increased, but there is some drone when flaps are open only for a small specific rpm, then no issues. This for me is a great mod and am happy with the exhaust, as i thought id be looking at a cat back as soon as they would be out.

I just noticed this product as its new might be what some are looking for the error codes.

Thank you - very much appreciated

Thank you - very much appreciated

Glad to help.

There would be no power loss with valves open so they clearly must have been closed to lose power.

[defau1t]

The "valves open losing power" issue was a debate topic on r8 v10s for several years. sounds like another car, another debate, ugh. I don't know who to believe, but seeing both sides on the r8 forums arguing made me more confused

There might be a differance in the europe/US models. Here is the youtube video of the tuner. It's in german.

Yep indeed, if you pull out the valves then the engine gets some error codes. Because of these codes the engine gets less power at a higher speed. The matter is to use a certain system to circumvent these error codes via the adapters you See in the above links.

In this video he speaks clearly about the less power with the valves pulled out...

[ostjj]

Yes, the peak hp loss is 20hp buth at the some points on the curve its up to 70hp

Think you are wrong..
He clearly says that with the valves pulled out at 6000 rpm the engine performs less -70hp and -80 NM.
On the curve you can see it too ...
The thin line is in normal mode with the valves pulled out..
and the thick line is in dynamic mode with valves in.
Of course the valves are open in dynamic mode, but here the engine does not get any error.
And that's what it's all about now

I believe your correct, error code is what the issue. There's more than likely a set of parallel contacts over the valve contact with a limit switch and status switch in series. If said condition is met open valves etc at certain rpms, if no reduce system output. More or less its putting the system in a limp mode as theirs no status on a certain contact within the system requirements. probably a normally closed held open valve contact with said limiting contacts.
