Default Problem Exhaust Flap - 05-02-2019, 10:54 PM

Hi, i have the problem that the Exhaust Flap every 10-15sec open and closed alone. I have the last EWG Soft. My car is a bmw 435i from 03/15. There must be an error in the JB4 or the jb4 doesnt work right with the bmw performance exhaust. If anybody has a tip for me let me know please. I tried an older firmware it is the same.

Does the bmw PE even have an exhaust flap?

I have the same issue on my newer 2016 435i MPPK w PE. I had to reset to OEM to stop the constant and annoying opening and closing flap.

Is that the electric motor drive noise I have been hearing while I sit at idle every minute or so?
I have been wondering what that is. I have AWE Exhaust, so the drive mechanism is just mounted but not connected to any actual flap.

Default Same issue on custom exhaust - 01-02-2020, 10:28 PM

I am hearing the same thing on a custom made exhaust. I cut the flap module off my stock exhaust and put it on the new unit. It has the same affect. Every minute or so while I park the flap opens and closes.

Any solution for this????
