1. Cable routing

In order to avoid disturbances, precisely adhere to the prescribed cable routing paths in the vehicle! Under no circumstances use so-called „Scotchlock quick-action connectors“ since they can trigger disturbances in the vehicle’s electrical system!

Take particular care when installing cables in the vehicle to ensure they are not kinked or damaged otherwise faults may arise which are then difficult to localise. The costs incurred will not be reimbursed by BMW.

2. Equipment installation

Before starting work, check the specified installation position!

Only use BMW-approved parts for installation!
