In the event that an M1.x control module needs to be replaced or recoded the process can be accessed through Progman with CIP 15.0 or higher.

To perform the procedure from CIP the Model series must be selected.

Then select the body (E32, E36 ...)

NOTE: For vehicles produced with the M42B19 engine (M1.7.2 Engine Control Module) a replacement EPROM was made available for vehicles produced 1/94-12/95 to address a service issue. Since the control module for this engine requires a variant code in order to assign the correct operating data to the program a variant code must still be assigned to the module upon installing the EPROM.
