Does the gear lever have to be in M/S?

As soon as I open the door the gear lever automatically resets back to the right.

Will check the connection to see if the plug is mated fully
No, it doesn't mate, and the shifter will return itself to centre when you're in 'P' mate like you said....
Flap should still open in sport/sport plus when in park

Just been for a spirited drive and it still won't open. Checked as soon as I pulled up and it was still closed.

Left it in sport parked up for another 5 or so minutes and still closed!

The connector is definitely mated fully so I'm unsure what's going on!

Odd. Could be coding/software bud? I'm still running 03/2019.48 🤷🏻

I'm on 11/2019 and I was adamant the car was quieter after the update, maybe this is why?

Will do some more experimenting but maybe interesting as a few others have complained their cars have got quieter on the same update. Could be unrelated but would make sense!

Unplugged mine then I plugged it back in I swear the burbles are quieter now. Could be psychological. Anyone know if the valve defaults back to normal operation if I just plug black in or is there an order of operations I need to follow similar to unplugging?

Plugging it back should be enough?

I still can't get the right hand valve to open in park whilst in Sport. Even after a good 15 minute drive in sport it won't open in park.

Can anybody who runs 11/2019 confirm if their valve will open in park?

Sorry for bringing up an old thread
Just wondering, does the exhaust flap remain closed when cold start the car? If I go sport mode, then hit the start button, does the flap suppose to open?
Ideally, I just want a louder cold start but comfort mode to stay quiet like stock.
