Hi all,

I’ve recently got an Audi A3 1.4 TFSI 8PA (2010) and I’ve chucked the OBDII sensor in there and it gives me the engine code P0470 and it mentions something in relation to the ‘exhaust pressure sensor’ not working properly/something to do with the air pressure reading not aligning.

I was wondering whether anyone knows where I can find this sensor - I’ve been looking for ages and the closest thing I can find that matches is the MAP sensor? Can anyone confirm that this is the right thing?

My car went into limp mode a few days ago and it reset when i restarted the car so hopefully its nothing too major and can be fixed from this sensor.

Thanks
