But I would like to use remote features, possibly by typing in the donor vin to connected drive when registering the system But would like the car to more or less function like before |

Likewise, you need the TCB part number to determine how old the TCB is as 3G is planned to Sunset in UK in 2020 which might make your unit a boat anchor after all this. And how do you know that the TCB of the donor car isn't already registered to the previous owners with BMW? These are things you MUST know before possibly wasting time installing something that otherwise will never work as you intend it to. |

As you cannot swap your eSIM from your current TCB as it was stolen, you would essentially swap (or actually install in your case) the TCB unit WITH A CAN filter and register it to car. Do not attempt to change the TCB donor VIN. You could then see if it works. Having never done a TCB retrofit, if it doesn't, you might need to also install a CAN filter on the HU and then code your HU VIN to match the donor TCB VIN. This would most likely require new FSC codes as well. By putting CAN filters on the HU and TCB, You have isolated the donors VIN from yours. At this point, your M140 should appear as the donor's X1 to BMW. |
