Thread: Front windows "One Touch Down"

Here's the official operation mode from the manual, they are all the same, that 0.4 second thing is the gist of it

One touch mode automatically lowers the window to its fully open position, without the need for the window switch tobe kept pressed for the duration of the window travel. One touch mode is initialised if the window switch is pressed
for a period of less than 0.4 ± 0.2 second. One touch mode continues to lower the window until the BCU detects:
l A stall condition exists (window has reached bottom of travel).
l Window switch is repressed in either direction for more than 0.4 ± 0.2 second.
l The BCU has operated the motor for a period greater than 10 ± 0.2 seconds.
