hi im having problems with my mk2 superb 1.6tdi error code p0238 turbo boost sensor circuit a I have replaced the sensor on the intercooler pipe and its fine until we have cold weather if the air temp drops below 4c the car will go back into limp showing the same error code glow light flashing and the skiddy car symbol in the top of the speed clock not the abs symbol but a bigger Samish type of symbol ??? any ideas why when its cold weather is there 2 boost sensors ?? any help please  

Which sensor did you change, G31?

 

It was the 1 on the bottom intercooler pipe
