Hey I was wondering if anyone can help me,

Our skoda vrs 1.8 20vt AUQ is acting like it's running out of fuel we've put fuel in Incase the gauge was broken, still running like it Fault read it code P0238 is showing manifold pressure / boost sensor (G31) signal too high. The warmer the car gets the worse it gets it's not in limp mode has anyone come across this before not 100% convinced it's the sensor thinking more of the fuel pump

Any help would be great thanks

Is less likely that a fuel pump will give such simptoms.

Just replace the sensor

Temp sensor? If the ecu is getting a bad signal from the temp sensor the fuelling might be off?
