Rear Electronic Module (REM), Replacing

Rear Electronic Module (REM)

Preparations

CAUTION: New software can only be ordered after the control module has been installed in the car. VADIS/VIDA reads off the new control module identity which is required to order the correct software.

Always check that the control module and control module box connectors do not have bent or damaged terminals or socket/sleeves. This may have been the cause of the fault.
