    Unhappy Help! No ENET communication with vehicle after repairs

    Vehicle: 2017 BMW 440i

    Background information:
    Client approached me with a no start issue. Codes in DME indicated EWS timeout. Scanned with ISTA and found lack of communication with modules on PT-CAN. After a bit of diagnosis, discovered there was a break somewhere between the KOMBI and FEM as the resistance was reading 120 instead of 60. Bridged the wires below which resolved the issue in regard to resistance and PT-CAN. All repairs were performed with the battery disconnected. Car was able to start successfully.

    Issue:
    Now, I'm unable to scan the car via ENET. OBD port has power and ground. When plugging in an MHD black wifi adapter, it creates the wifi network therefore indicating it has power and ground. The same adapter was being used prior to the repair to scan the car and it worked with no problem. The adapter was tested on another vehicle and it connected successfully. I was hoping it was just a coincidence but unfortunately I tried with an ENET cable and the issue persists. The computer does not detect anything on the ethernet port and the MHD adapter doesn't show a connection with the vehicle has been initiated (there's a green LED that lights up when connected). The OBD port pins 6 and 14 read 60 ohms indicating the terminating resistor is good but that doesn't matter for ENET. The OBD port pins all have continuity to the FEM for the ENET connections.
    I tried undoing the repair for the PT-CAN and communication over ENET was not restored. I tried unplugging the headunit (it's the only module that uses ENET) and communication was not restored. We have tried disconnecting and reconnecting the battery multiple times to no avail. The car functions fine (engine runs and drives, cluster works, HVAC works, etc).

    A replacement FEM is on the way but hoping to see if there's anything else I can check. All modules communicate fine over D-CAN.
