Further to that. This symbol only happens when the ignition is switched of after parking. The handbrake is manual and is applied and works. It is an smg box and is in neutral when this symbol comes on it sings and the N symbol below it flashes.A symbol pops up on my 2004 645ci.
Best way to describe it is a side view of the car and above it is an arrow pointing towards both ends of the car. I can't find it in the manual or searching online for warning lights.
Any help appreciated.
