ผมเข้า N โดยวิธีนีครับ
From the F30 manual page 296:
Automatic transmission:
1. Release the parking brake, refer to page 63.
2. Drive into the car wash.
3. Depress the brake pedal as needed.
4. Engage transmission position N.
5. Switch the engine off. In this way, the ignition
remains switched on, and a Check-Control
message is displayed. Transmission position P with the
ignition off.
When the ignition is switched off, position P
is engaged automatically. When in an automatic
car wash, for example, ensure that the
ignition is not switched off accidentally.
The vehicle cannot be locked from the outside
when in transmission position N.
A signal is sounded.
