Window Problem

Post by Z4 Forum AMW » Sat Jul 07, 2007 10:35 pm

I have just been on holiday for 2 weeks only to come back to find my 2003 Z4 completely dead with a flat battery - I have charged it up and got the car going again but I think the windows no longer drop and the go back up that small amount to get a good seal with the roof........

Does anyone know how I can sort this out - I have seen some instructions for cars from 04/04 but what about those prior???

Help before it rains......

The Official Reset Proceedure

--------------------------------------------------------------------------------

Courtesy of a BMW tech on another forum, ...with thanks.


Initialization is performed on the power window switch of the relevant door.
Requirements for correct initialization:
• Initialization with engine running
• Convertible top, doors and windows closed

Initialization comprises:
• Erasure of initialization
• Reinitialization

An initialization must be performed:
• In the event of malfunctions, e.g. no one-touch control function, no opening or if available no comfort function is possible
• After the power window drive has been replaced
• After work is carried out on the power window mechanism
• After a power supply interruption, e.g. disconnection of the battery or disconnection of the power supply to the door
• After the door window glass has been removed and installed or replaced
• After adjustment work on the door window glass
• After adjustment work on the convertible top
• After replacement of seals

Erasure of initialization:
• Open door window glass fully
• Operate power window switch in "Open" position four times within 10 seconds

This erases initialization of the power window, anti-trapping protection and toll function are inactive.
Check whether one-touch control (toll) function is inactive, otherwise repeat procedure.

Reinitialization:
Avoid a break between the two steps!
• Open door window glass fully
• Operate and hold power window switch in "Close" position (second switch stage)
• Once the upper end position has been reached, hold power window switch in "Close" position for approx. 2 seconds longer
• Open door window glass fully
• Operate and hold power window switch in "Close" position (second switch stage)
• Once the upper end position has been reached, hold power window switch in "Close" position for approx. 2 seconds longer
