It'll be really easy to tell if it's closed in cold weather...you'll have exhaust coming from only one side on startup. Pretty easy to put the fuse back in and start over.

My car has been running flawlessly and it always makes me happy hitting remote start and walking up to the car!
I understand it is pretty easy to check and reset but my point is it is not a 'set and forget it' kind of mod. One should keep checking if the flap has closed every time to avoid possible issues as mentioned in the x3 post.

Just a friendly warning to others who might have missed possible issue with this mod.
Ok, just know it's not an apples-to-apples comparison with the G01. While both are done via a fuse pull, on the G05 you actually have to be at WOT driving vs. the other triggered after warm up and done at idle.

It was pretty hard to get the valve opened and I'd expect it will never return to back normal position. If that did happen, my only risk is slightly more exhaust back pressure, but that can be fixed by simply opening the trunk, pulling the panel and plugging one fuse back in (oh my!).

Man, this forum is getting really lame. We may as well be talking about Sienna minivans...
Please don't get me wrong. I want to try this as well and I'd like to thank you for initiating the post.

You did acknowledge that there is a risk. I'm just stating the fact the possible issue in the x3 forum that I found buried in later post. I figured it is something that interested enthusiast would be good to know.
