That's correct, when I taped the split hose up the knocking disappeared and although I have not yet been able to replace it the engine is still silent

Many thanks for the information. I had a knock on idle, which I traced to a split hose. Didn't know what the part was called to be able to order a replacement.

Hello all. I need some help identifying a hose that has split under the engine cover of my Karoq. It's the one conected to the black box with the white square sticker on it. What is it for please? Thanks.
