Important information The retrofit kit is for use within the BMW dealership organisation only. In addition to the basic kit the control element required by the customer must be ordered separately. The wiring harness supplied with the installation kit is only to be fitted if there is no white/green cable on the 6-pin plug X764 (on the auxiliary heater). If the wiring harness is required, the installation time required will increase to approx. 4.5 hours. On cars without a high on-board computer or on-board monitor the auxiliary heating system can only be operated using the remote control, the Thermo Call or the time switch. Do not kink or damage the cables during the installation work since otherwise they may cause faults that can later only be identified by extensive additional work. The costs incurred as a result of this will not be reimbursed by BMW. If the specified PIN chambers are occupied, bridges, double crimps or twin-lead terminals must be used. After the installation work the retrofit auxiliary heating system must be coded using DIS or MoDiC via the Retrofit path. Target group The target group for these installation instructions is specialist personnel trained on BMW cars with specialist knowledge of vehicle electrical systems. Work: All servicing, repair and installation work on BMW cars is completed at your own risk. All work is to be carried out using current BMW - Repair manuals - Circuit diagrams in a rational order using the prescribed tools (special tools) and observing current health and safety regulations. Information on operation Operating the auxiliary heating system places a strain on the car s battery. To avoid starting problems and to stabilise the car s electrical system we recommend that you drive the car adequately in the period when you use the auxiliary heating system so that the battery remains well charged. Recommendation: 3 minutes auxiliary heating system use = 3 minutes driving time.! Danger of poisoning! The auxiliary heating system must not be operated in enclosed areas such as garages or workshops (not even using the time switch or remote control). The auxiliary heating system must be switched off at filling stations and/or filling points to eliminate the risk of explosions.
