67 62... Notes on initializing power window unit in front door

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
• If necessary, after an open circuit, 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

Initialization  is performed on the power window switch of the relevant door.

Requirements for correct initialization: 

• Terminal "R" activated
• Doors and windows closed
• Sufficient battery voltage; connect charger if necessary

Initialization  comprises:

• Erasure of initialization
• Reinitialization

Erasure of initialization: 

• Open door window glass fully
• Actuate power window switch in "Open" position (second switch position) and hold down for between 15 and 20 seconds

This clears initialization of the power window. Anti-trapping protection and one-touch control (toll) function are inactive.

Check whether one-touch control (toll) function is inactive, otherwise repeat procedure.

Reinitialization: 

• Close door window completely
• After upper end position is reached, interrupt actuation of power window switch and then hold switch again for approx. 1 second in "Close" position (second switch position)
• Open door window glass fully
• After upper end position is reached, interrupt actuation of power window switch and then hold switch again for approx. 1 second in "Open" position (second switch position)
• Close door window completely
• After upper end position is reached, interrupt actuation of power window switch and then hold switch again for approx. 1 second in "Close" position (second switch position)

This completes initialization.
