Foult P1945 appears during DPF burnout process. Radiator Fan (5Q0959455BJ ) was replaced on a new one. Radiator Fan tests are OK results by VCDS. Relay (4H0951253A) was replaced on a new one. The fan harness has been checked and shows no signs of damage. i don't know about correct resistance for harness (should be check too). ECU's still shows foult P1945 (during DPF burnout process). ECU software is 9500 version should be higher? Does anyone have an idea where to look for the cause of the problem?

On screen First value is the for sensor G62 50deg - sensor on engine. Second value for sensor G83 is the cooler radiator outlet one - 88 deg which is calculated by ECU when car has only G62 sensor.

Hi Do you have more information: - The coolant temperature on the dashboard rises above 90°C - by how much (maximum temperature)? - The G83 temperature sensor is stuck at 88°C. Maybe the car hasn't this sensor?
