All Functions of the Overhead Control Panel Not Functioning
If you receive customer reports in the above model vehicles regarding all functions of the overhead control panel (interior illumination, rain/light sensor,
Vario Roof) not functioning, this may be due to a software error in the overhead control panel (OCP) with Q level Q1. The condition may be corrected
after the CAN bus goes to sleep, however this condition may reoccur at some later time. If only the first version spare part number is available (A171
820 14 01 or A171 820 15 01), replace the OCP only with a level Q2 part, refer to WIS document AR82.20-P-1000V. If the newer version spare part
number is available (A171 820 20 01 or A171 820 21 01), any Q level is okay.
