    Fault code is for the lambda sensor wiring.  I assume the garages have just been replacing the sensor instead of checking the wiring?  Best bet would be to get an auto electrician to check the wiring.

    Check all the wiring "carefully" and look for damage to the wires and/or corrosion of the connectors. When the lambda sensor was replaced did you use a genuine Ford part ?

    Has the circuit to the lambda heater circuit been checked with a multimeter ? If yes has it also been load tested? Use something like a 21W lamp to ensure that the circuit is able to supply current.

    Are you using FORScan to read all the Ford specific codes
