Yes, the E70 does have the Parked Car Ventilation option.

Page 110 of the owners manual covers it. This allows you to purge the air in the car twice a day at times you select.

Start Menu > Climate > Parked Car Operation > Automatic Ventilation > Parked Car Ventilation

I remember buying my 2001 X5 3.0 and learning it was only included in the 4.4 model. I was so ticked!! It would be nice to vent out that hot air in the summer before you get in the car after work.
