    Not sure if the TDI has one or two sensors? Also if it has two which is bad? Upstream or down stream?
    Dealer wants $400+ to replace. I can and want to do this myself.

    That's the code for #1 so I'd refer to the parts diagram to double check.

    You could follow the plug, unplug, see if additional code pops up.

    VAG use 5 Exhaust Gas Temperature (EGT) Sensors. These have been talked about before if you search?

    Exhaust Gas Temperature (EGT) Sensor 1 (G235)
    Exhaust Gas Temperature (EGT) Sensor 2 (G236)
    Exhaust Gas Temperature (EGT) Sensor 3 (G495)
    Exhaust Gas Temperature (EGT) Sensor 4 (G648)
    Exhaust Gas Temperature (EGT) Sensor 5

    If you fit a new sensor I think you will need access to VAG-COM\VCDS to calibrate.

    VAG Error Code: 16928/001348

    EOBD II Error Code: P0544

    Fault Location:
    Exhaust Gas Temperature (EGT) Sensor 1 (G235), Bank 1 - Circuit Malfunction

    Possible Solutions:
    Check/Replace all faulty Wiring/Connector(s).
    Read Measuring Value Blocks (MVB).
