Good evening started to change the water pump that has failed on my 2015 audi s4 got a replacement pump and now i have removed the old one you can see in the pictures that there is what looks like a small vacuum pipe on the original and not on the replacement, can anyone shed some light on this please?
Do i have the wrong pump and or is it all good?
Thanks in advance!
