Default exhaust flap wont stay open? - 11-19-2020, 07:06 AM

2021 supra
firmware 17 w bluetooth

I know how to control it but if during a couple days of driving as i switch between sport and comfort the flap will follow comfort button and be closed.

I assumed, and i may be 100% wrong, that when you select flap open on JB4 it would stay open until you chose to close through JB4?

Yup. In my G20 330i, it stays open in all modes. Only when I remove the JB4 does it revert back to stock settings.

What firmware version? Not had any reports of issues. We've added a full time "closed" setting to some versions (right blinker). Does your version have that setting?

Thanks Terry,
It has acted fine the last couple of days. Only thing i can think is that when I upgraded to v. 17 it reset.

I know i have to update to v 18 asap

With both arrows flashing DME runs the flaps and will open/close depending on temperature and its internal algorithm.

Understood.

I am not changing the status of the flap and it should be staying open until I effect a change. Like i said, not a biggie but worth noting.
