i would suggest you go to your trunk with a size 8/10 spanner, remove the 2 nuts that hold the bracket to the MULF and take out the module. take a good photo of the label of the MULF model number and cross check it on realoem. there is no reason why a MULF needs a TCU to work properly since each can exist on it's own for bluetooth functions.
