Hi all, whilst I was fiddling about about removing the air temp sensor & a few other bits to clean I managed to snap the little pipe that's to the left of the attached image
I've glued it back together & used gaffer tape to reinforce it but I'd rather replace it now I know it's been bodged.
Does anyone know what it does? (my car drives fine incidentally) I was hoping to source a replacement for the weekend when I'm joining the blanked EGR valve club!
Thanks in advance for any advice offered.
