As a BMW owner, I like the quiet "click" when I remotely lock my car. I was surprised at the horn beep on my new 500E. I called customer service, and they said there was currently no option to turn it off. Since adding this feature would not hurt anyone who likes the horn beep, I'm hoping we can get some support for this option on the 500E forum. Please chime in softly... My next door neighbors would appreciate silent locking when I arrive late at night!
(And don't we like it that our electric car is quiet?!)
