* If during the course of replacing the EPROM you find an aftermarket EPROM in the original DME:
a) Contact the customer and advise them that BMW recommends that such an EPROM be removed and replaced by a BMW-approved EPROM and software.
b) If the customer insists on keeping the non-approved EPROM installed, advise them that this may cause nonconformance with environmental emission laws and regulations, plus it may affect the warranty coverage of their vehicle.

a) Abort the Service Action.
b) On the repair order note that the customer insisted on keeping the aftermarket EPROM installed and does not wish to have the Service Action performed.
