  1. This description of replacing a knock sensor provides no detail or explanations. It is too vague. Having replaced a knock sensor on the X type, I would not rely on this post. There are much better posts on the internet with photos and details

    1. I just tried doing just that and spent hours looking through all the videos after doing a search for x-type shock sensor replacement and didn't find one I found everything else trouble is utube uses every word in the search so all kinds of Jaguars show up and all kinds of repairs but NO X-Type shock sensor repair

  2. Hello what were your symptoms of your failing Knock Sensor thank you. .

  3. I saw another post to replace the shock sensor on a X-Type complete with description pictures trouble is I cannot find it now I sure would like to find it again, also how do you get the vacuum lines unclipped I have tried pressing down on the part closest to the manifold with a probe looks like a solid ring, but it dont move is there a special tool?
