P0471 Exhaust Pressure Sensor 1 (G450)

Hello everyone,

Yesterday, I received the following error message, apparently even before starting the engine:

001137 - Exhaust gas pressure sensor 1 (G450)
P0471 - 000 - Implausible signal.
Environmental conditions:
Error status: 01110000
Error priority: 0.
Error frequency: 1.
Time: 0.

Environmental conditions:
Speed: 0 RPM.
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 message, and I didn't experience any subjective limitations or issues.
I deleted the error, and after turning the ignition off and on again, it's gone for now.

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

Best regards,
Azrael.

The sensor is used to calculate the amount of soot entering the DPF. As far as I know, there is a modified version available, as these sensors often fail.

I would renew it and check if a software update is available.

Okay, I'm ready. Please provide the German text you want me to translate.
