When UVS control module (N52) circuit 15 signals "ON" and the Vario roof is not in the locked position.
Flashing tight when switch is actuated:
Flashing frequency = 1 Hz:
-
When driving (V > 5 km) and when Vario roof is not closed.
-
In the event of interruption or non-actuation of the Vario roof procedure due to absence of input values or incorrect values
Flashing light when switch is not actuated:
