Open exhaust flap mod..please help

nwills · 01-16-2013, 12:05 PM

So I tried to do what is explained in many places on this forum and described as being a 5 minute easy modification.

The problem is that my flaps are closed by default. When the car is in the garage the flaps are closed so if I remove the rubber tube that is attached the flaps are closed regardless and stay that way!

I pushed on the flaps with a screwdriver and they almost felt spring loaded?

If I zip tie the rubber tube and go for a drive will the flaps open and stay that way after?

That's a no go for me!

My flaps are closed by default. When I turn on the engine they don't close since they already are.

I removed the tube and closed it off. Went for a drive in Sport+ mode and when I returned, parked the car and turned off the engine...the flaps were still closed!!

I believe the same result can be achieved simply by unplugging the actuator electrically.

I have done this before quite easily in my old E92 335i without any error codes or noticeable side effects for years. Here's a post on how it was done on an E92:

Anyone know whether we can do the same for the F12/13 650i?
