I ended up going with Remus. I will try and see which actuators and cable they use if they're OEM

Please do. If they are the M/MPE actuators then that gives us hope. If they are the non-M then it confirms my findings and we'll have to get them together with the Y cable.

how do you constantly have the flaps open? I'm getting so bored of having to keep doing the button in the boot before start up. If you're able to please advise the steps for constantly having the flaps open it would be most appreciated! cheers

Unplugged the main harness (the big plug) from the BT controller in the trunk while the flaps were open. Takes 30 seconds, no crawling under the car.

thanks for the quick response, forgive me if I'm being a bit stupid here but which plug is it I need to take out in the below pics? Only recently got the car so don't want to go and break anything pulling out cables pretending I know what I'm doing

The big grey plug that has the bundle of 4-5 black cables going into it.

Yeah, no problems, codes, or lights. Other than getting power from the battery the system is completely standalone so it can't throw any codes/lights.

The only problem is that the cold start up now is just too loud

As experiment, I tested mr_lab_rat's easy hack: simply unplugged the big grey plug (featuring black cables) in the boot when the MPE butterfly valves in pipes #1 and #4 are in 'open' position. And effectively, the valves remain permanently in 'open' position (thus also after engine shutdown) as long as the plug is not plugged back in. Explanation is obvious: as power to operate the valves is cut off, the valves go into some state hibernation keeping their last position before the power cut-off.

So as a follow up, my local BMW dealer diagnosed and agree flaps were closing on there own. Internal parts are not serviceable so they have ordered a new exhaust from Germany...

Hi, to explain how Remus does it, they provide a duplicate valve controller, you remove the one from your stock exhaust and use their provided Y cable to control both actuators via the stock software/drive modes.

I dont know if it's their own Y cable or a BMW item. I can open the box before I go to get the install done and see if I can get info on the cable. TBH someone who has the know how could whip one up and sell to MPE owners. I cannot see this not working if the fix is simply splitting the signal to both actuators (stock, replacing the MPE ones)

My guess would be that they use the non M actuators (like the stock M2 exhaust) and in that case they can use the OEM BMW Y cable.
If you can get the part number fro the actuators that would be great.

From Remus's website it seems like it's a second of the stock that they provide. I work all weekend so I can't open the box but I'll try to do it by the time it's installed next week or while it's getting installed.

MPE not working

The remote switch is not opening or closing the valves in my MPE. I read somewhere that this is a Bluetooth remote. The dealer replaced the entire iDrive "head unit" and I suspect that as the cause of the problem. Right now, they are clueless as what to do, and I have the car scheduled to go back in April.

Does anyone know how to initialize or "learn" the remote? Even if it is only something that the dealer can do, if I had some instructions for them, I'm sure they would appreciate it. And I sure would!

Thanks,
Michael

MPE has nothing to do with the headunit that's their first issue.
it's an independent system.
I don't have the instructions for attempting to re-sync it, usually they just replace the button itself or the exhaust.

Thx @MrOhnoez. Is the "bluetooth" information correct? Just wondering.

OK, now I've read the entire thread and I see that it is BT and that it is a common failure point. I wonder if I should first check the fuse, just in case it's as simple as that. Anyone know which fuse it is?

Taking it to the dealer for them to keep it for two days and say "we don't know what's wrong" is not my idea of fun.

I'll also replace the battery as well, just in case it's too weak.

It gets discouraging, having a new car with so many issues.

For anyone still following this thread, or someone who stumbles across it later and was curious about my issue:

The dealer looked at the car yesterday and reported that I had a "loose ground" for the MPE. I asked, "could it have anything to do with my last service?" and they replied, "probably". I do believe that they charge the battery before loading new software, and they probably disconnect it from the car first.

I have stock valve on my Dinan free flow res delete exhaust. The flap is actuating that I can tell but there is zero difference in sound at idle or up to 3k rpm. Does that sound normal? At WOT it is quieter. Shouldn’t I hear some difference at idle?
