If you read what I'm asking, I don't want to deactivate, just lower the default time from 60 seconds to 5 seconds for example as I have in all my bmw F series ... But in mini I was not able to get it, to park in the garage very annoying.
Minis don't feature the whole functionality of the bimmers.
Just like you can't adjust the parking mirror, there might be no option to decrease the beep time of the seat belt warner.
As I said, I only know the option to deactivate it.
Since its no topic for me, I didn't dig in further.
Maybe the option is just not visible with bimmercode and you can only access it with esys.
