P0471 - Exhaust (EGR) Gas Temperature Sensor 1 (G450)

Hello everyone,

I received the following error log yesterday, apparently even before starting up:

001137 - Exhaust Gas (G450) - Pressure Sensor 1
P0471 - 000 - Implausible signal
Environmental conditions:
Error Status: 01110000
Error Priority: 0
Error Frequency: 1
Time: 0

Environmental conditions:
RPM: 0 /min
Speed: 0.0 km/h
(no unit): 40.80
(no unit): 0.00
Air mass: 5.69 g/s
Temperature: 270.0°C
Temperature: 27.9°

I drove 30km with the error, without any subjective limitations.
I've deleted the error and, after turning the ignition off and on again, it's gone for now.

Today, I started the engine twice again, and the error message didn't reappear.
Question: Would the error occur immediately again, or would it only reappear after a certain amount of driving time?

Best regards, Azrael

Der Sensor wird benutzt zur Berechnung des Rußeintrags im DPF. Aifaik gibt es eine geänderte Ausführung, da diese Sensoren sehr oft versagen.

Ich würde ihn erneuern und erkundigen ob ein Softwareupdate zur Verfügung steht.
