Hi,
I recently bought a 2nd hand BMW 525 TDS Touring (E39) and everyday I discover some new features in this nice car.
This morning I noticed that, if I go keeping the air conditioning active, when I stop the car and switch it off, the small ventilation fan keeps working for long time.
To better understand the problem, I made a test stopping and closing the car with myself inside and I could notice that the small fan keeps working for at least 10 min.
Now I have not clear if this is a defect (which I should fix soon to not loose the battery charge) or it's a normal behaviour (maybe there is timer longer than 10 min).
Any idea on this ?
Thanks. Alberto
