54 0 ... Notes on panorama glass roof (initialization/normalization/learning of characteristic curve)

WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Initialization comprises:

Normalization
Learning characteristic curve

The mechanical end positions are recorded and stored during normalization.

The characteristic curve is learnt immediately after normalization.

When the characteristic curve is learnt, the mechanical closing forces of the panorama glass roof are recorded and stored for correct operation of the anti-trapping mechanism.

NOTE: Then carry out an initialization:

if the panorama glass roof has been mechanically moved by means of the emergency actuator
in the event of malfunctions, e.g. no one-touch function, no opening or no comfort function possible
after disengagement of the drive unit
after work is carried out on the mechanism of the panorama glass roof
after the control unit has been replaced

WARNING: There is no anti-trapping protection during initialization.

NOTE: Starting situation in accordance with following description:

Panorama glass sunroof closed
Floating roofliner completely open

Normalization:

Press and hold the switch in the "Lift" direction
In the event of delayed starting or sudden stopping of the panorama glass roof, continue pressing the switch in the "Lift" direction

After reaching the lift end position (A), keep the switch pressed for approx. 15 seconds further

Normalization is completed when the panorama glass roof in lift end position (A) presses again briefly in the direction of position (B).

Learning characteristic curve:

E53/E61/E83 only:

The curve is learnt manually in the following steps:

After normalization, keep switch pressed in "Lift" direction.
The panorama glass roof stops for 5 seconds in the final raise position after normalization.
Floating roofliner closes completely.
Floating roofliner opens completely.
The panorama glass roof then moves into the "Closed" position (learning of the "Closing from raising" curve)
The panorama glass roof then moves into the "Open" end position and immediately back into the "Closed" position (learning of the "Closing" curve).
Floating roofliner closes completely.
Release switch.

E63 only:

The curve is learnt manually in the following steps:

After normalization, keep switch pressed in "Lift" direction.
The panorama glass roof stops for 5 seconds in the final raise position after normalization.
Floating roofliner closes completely.
Floating roofliner opens completely.
The panorama glass roof then moves into the "Closed" position (learning of the "Closing from raising" curve)
Floating roofliner closes completely.
Release switch.

NOTE:

The entire operation lasts approx. 75 seconds
Learning of the curve is terminated when the switch is released
If the switch is released in the meantime, the entire procedure must be repeated
On completion of successful initialization, the corresponding messages in the check control and the control display go out
Carry out function check (tip function, anti-trapping protection and, if necessary, comfort function)
