on this ecu i have one dtc unerasable : P0544 Sensor 1 for exhaust temp bank 1

i change original G235 egt (before turbo) with new G235 but the dtc is always present.

i test glow plug and wiring and everything is fine...i need disconnect G235 and erase dtc and recovery, can anyone delete G235 from ecu managment?

Hello did you find a solution for this, I have a 1.6 and a 2.0 Vw passat with this problem, found there isn't 5 volt coming out of the ecu but only 4. When I disconnect the sensor g235 the car doesn't even set a fault code, only when you drive it sets the code once in a while.
Maybe someone who has had this problem before.

i check all wire from plug to sensor and i found one wire interrupted...i solder this and problem solved.
