p0237

Hi 2019 transporter 150hp diesel dsg I get the eml light when starting the engine after it has been sitting for some while. Normally it will not light if it's just a short stop. I read the fault code P0237 via VCDS. I have tried replacing both map and maf sensor. Also tried wiggeling(?)...

Hi guys I have the fault code as listed below and have changed the sensor but still have the fault code showing after reset. I have no loss of power or any other problems apart from the waring lights. would anybody have an idea of what to try next, Thanks.
